National Survey Of Familty Growth, Cycle 4 (1988)DSN: CC37.NSFG88 ABSTRACT Introduction The National Survey of Family Growth (NSFG), Cycle IV, was conducted in January through August of 1988 by Westat, Inc., under contract to the National Center for Health Statistics (NCHS). In-person interviews were conducted with 8450 women 15- 44 years of age, of all marital statuses. The data from the NSFG are used by the National Center for Health Statistics as the basis for a series of reports on fertility, family formation, contraception, and related issues (see page 7). In addition, agencies that support the NSFG use the data for their own research programs. To make the data more widely available, a standardized micro-data tape has been prepared for distribution. This tape documentation manual contains a detailed description of the data tape. The tape consists of the original data for the respondent and interval files, and a set of "recodes." The respondent file includes a wide range of background characteristics, cohabitation and marital histories, and measures of fertility, use of contraception, fecundity, birth expectations, and use of family planning services. The interval file contains detailed pregnancy histories. Recodes are new variables that combine the code categories of one or more original variables in ways that should simplify analysis. Suggestions for Users The following is a summary of the basic information required to use the NSFG Cycle IV Public Use Tape. See specified sections for more details. Organization of data (see page 8). The data have been divided into two files. The Respondent file contains one record for each woman in the survey and the Interval file contains one record for each closed pregnancy interval (completed pregnancy). That is, in the Respondent file the unit of analysis is the woman, and in the Interval file the unit of analysis is the pregnancy interval. The Respondent file contains the following questionnaire items: all of Section A; questions B1-B10 and B47-B58 in Section B; questions C1-C11, C26-C49, and the method calendar in Section C; all of Section D; all of Section E; all of Section F; the self- administered questionnaire. The Interval file contains the following questionnaire items: questions B11-B46 in Section B; questions C12-C25 in Section C. Combining Respondent and Interval files. To combine data from the Respondent and Interval files, use a computer program that can process files with records of two or more types. The record type is located in Tape Location 6-7 in both the Respondent and Interval files. A code of 0 indicates a respondent record and codes of 1-13 indicate an interval record. Weights (see page 23). Analysts should use the weights provided. The final weight is located in Tape Location 2568-2574 in the Respondent file, and in Tape Location 366-372 in the Interval file. Recodes (see pages 50 and 62, and Appendix 1). Many items have been recoded to make them more useful for the analyst. Before using the original data item, the analyst may wish to check whether a recode exists. Missing data have been imputed for recodes. Dates (see page 14). All dates reported in the survey have been converted to century months. Standard errors (see page 22 and Appendix 6). Standard errors which take into account the complex sample design of the NSFG have been estimated for Cycle IV using the balanced repeated replication technique. A short-cut method for estimating the standard errors of statistics is provided (see Appendix 6). If the analyst prefers to make his or her own estimates, however, 100 replicate weights appear on the public use tape in Tape Location 2754-3553 of both the Respondent and Interval files.

Publications from the National Survey of Family Growth, Cycle IV The National Center for Health Statistics has planned reports from the NSFG, Cycle IV, on the following topics: contraceptive use; use of services for family planning and infertility; number, timing, and wantedness of births; fecundity impairments including infertility; cohabitation, marriage, and divorce; sexual activity and the risk of sexually transmitted diseases; and sample design, weighting, imputation, and variance estimation.

The Respondent file contains one record for each woman in the survey and includes most of the information from the interview. The Interval file contains one record for each closed pregnancy interval, and contains information about the characteristics of each pregnancy and any contraceptive methods used during that interval. That is, in the Respondent file, the woman is the unit of analysis and in the Interval file, the pregnancy interval is the unit of analysis. The Respondent file contains the following questionnaire items: all of Section A; questions B1-B10 and B47-B58 in Section B; questions C1-C11, C26-C49, and the method calendar in Section C; all of Section D; all of Section E; all of Section F. The Interval file contains the following questionnaire items: questions B11-B46 in Section B; questions C12-C25 in Section C. Data Preparation Using specifications prepared by the NSFG staff, the data were edited manually in the field and in the home office of Westat, Inc., the fieldwork contractor. Westat also conducted computer edits for acceptable codes and internal consistency of the data. Missing and inconsistent data items were resolved through data retrieval in the early stages of editing, and by examination of related items in the questionnaire in the later stages. As far as possible, inconsistencies in the data were resolved on a case- by-case basis, based on related data. If inconsistencies could not be resolved, the case was assigned as missing for original data items (see page 11). Missing values were imputed and flagged for any recodes based on those original data items (see page 12). Because of the complex skip patterns in the questionnaire, sometimes one group of women would be asked a question in one part of the questionnaire and another group of women would be asked the identical question in a different part of the questionnaire. When preparing the data tape, the answers to these questions were combined into a single data item. The question number given in the tape documentation reflects both of the original question numbers (for instance, D25_32). All combined questions have been noted in the tape documentation. During the course of coding the data, new code categories were sometimes added if a substantial number of respondents gave an answer that did not appear in the original questionnaire. All added categories have been noted in the tape documentation. An added category should be analyzed with caution because it is quite possible that other respondents would have chosen that answer had it been offered to them. For example, question A26 asks women who were not living with both parents at age 14 whether that was "because one or both of them had `died, they were divorced, or for some other reason" (TL 142). Some interviewers wrote a marginal note in the questionnaire that the respondent's parents were separated. A new category, "they were separated," has been added, but it is likely that some respondents whose parents were separated simply answered "some other reason." Inapplicable Questions Not all questions were applicable to all respondents. If a question was not applicable, the interviewer skipped to the next applicable question. With certain exceptions noted in the tape documentation, inapplicable questions are coded as blanks. Some computer programs read a blank as a nonnumeric character, but others read it as a zero. Analysts should take care to distinguish between blanks and zeroes in programs used with these data. The meaning of statistics based on responses to a question will depend, of course, on who was asked the question and who was not. Because of the rather complex skip patterns used in the interview, it is often not apparent who was asked a particular question. In the documentation, however, the description of the inapplicable (blank) code category for a question includes a precise listing of women who were not asked the question. In addition to consulting that list, it is recommended that the sequence of questionnaire items containing an item of interest be examined carefully to determine the implications of skip patterns for interpreting responses. The documentation for the recodes also provides brief descriptions of inapplicable categories. However, we recommend that the analyst examine the more complete definitions of' the inapplicable categories contained in the specifications for the variable or variables on which the recode is based. Missing Data Data are sometimes missing for an item because the respondent would not or could not answer the question, or because the interviewer did not ask the question. For basic data items, a refusal was coded "7" or "97," a "don't know" was coded "8" or "98", and a "not ascertained" (missing data because of interviewer error or for other reasons) was coded "9" or "99." Imputation For the majority of the recodes, values were imputed for cases with missing values. All imputed variables were flagged. Recodes are listed in the Respondent and Interval file Indexes (see pages 50 and 62), along with the tape locations of the imputation flags. The purpose of the imputation was to allow NCHS to produce internally consistent national estimates in its pre-planned Advance Data and Series 23 reports. We recommend that tape users use the imputed variables for most analyses. Results using these variables should be identical to results in NCHS reports using final (not preliminary) data. The following summary briefly describes the imputation procedure used in the NSFG, Cycle IV. The summary was taken from a forthcoming report from the National Center for Health Statistics, National Survey of Family Growth. Cycle IV: Sample design. weighting, imputation. and variance estimation. More complete information on the imputation procedure used in Cycle IV can be found in that report. The report will not be published before fall 1990. See page 7 for information on how to obtain a copy. The variables requiring imputation were grouped into 32 modules. Each module was imputed with a procedure known as hot-deck imputation. Within a module, the hot-deck procedure sorted the file so that similar women were close to each other. Each woman's answers to the questions in the module were then examined in turn. Whenever a woman had missing values for one or more of the variables, she was given the values for the previous woman with complete values (i. e., the previous woman's answers were copied to her record). Only the missing variables were changed; any complete (valid) values she had reported were left alone. The modules were imputed serially in separate computer runs so that each module was not imputed until the prior module was forced to be complete. The file was sorted~ by different variables for each module. In general, the frequency of missing values in Cycle IV was quite low. Missing values were imputed for 192 variables in Cycle IV. Of these, 133 had less than 1 percent missing data (fewer ban 85 cases), 22 had I to 2 percent missing (85 to 169 cases), 16 had 2 to 5 percent missing, and 5 had 10 to Il percent missing. No imputed variable had more than II percent of cases imputed. The 16 variables with 5 to 10 percent missing data were all measures of use of family planning services, including age at first family planning visit, month of first visit, 5 measures of specific services received at the most recent visit, and 5 measures of ways that the most recent visit was paid for. The five variables with 10 to II percent missing data were: education of the respondent's mother (EDUCMOM); month and year of first cohabitation or marriage (UNION1); type and outcome of first union (UNTYPE); duration of first union (UNIONINT); and the ratio of family income to the poverty level (POVERTY). All imputed data have been flagged on the public use tape so that researchers may do their own imputations if they wish. Date Codes During the interview, dates of events were asked either as the year alone, as month and year, or as day, month, and year. For this tape, month and year were converted to "century months" by multiplying the year by 12 and adding the number of the month, where January = I, February = 2, and so on. For instance, the century month code for February 1959 is (59 x 12) + 2 = 710. The century month form is convenient for computing an interval between dates. (Note: all century months codes occupy a five column field.) The century month codes from 301 through 1064 are shown in the array below with the years from 1925 through 1988 on the vertical axis and the months on the horizontal axis. The code for a given month and year can be found by reading across the line for the appropriate year to the column headed by the appropriate month. Dates that were refused or not ascertained are coded 99999. In a limited number of instances, 99595 or 99696 are used to indicate a response other than a date. For example, in question C-26, concerning the dates of periods when the respondent was not having intercourse, respondents who did not have intercourse after the first time are coded 99595, and respondents who reported no periods during which they were not having intercourse are coded 99696. All such cases are clearly indicated in the documentation For cases in which the year was given but the month was not, the first digit of the code is a 9 to indicate that the date is an estimate. The remaining four digits are equal to the century month corresponding to the month of June in the year given. Sometimes respondents were able to recall the season when an event occurred, but not the precise month. If a year and a season were given, the month was imputed as follows: spring was coded as April, summer was coded as July, fall was coded as October, and winter was usually coded as January.1 For cases in which dates were imputed from a season, the dates are not flagged. --------------------------------------------------------------------- 1 Winter was coded as December if coding it as January would have produced a date that was inconsistent with other data. For instance, if a respondent gave the date of an event as "Winter 1980," and other relevant information suggested that the event took place late in 1980 rather than early in 1980, the date was coded as December.

See Appendix 3 for a copy of the occupational classification system. Data Quality Considerable effort has been directed toward cleaning the data, and producing a consistent data tape. Inconsistencies may remain. Evaluation of selected data items has identified a few items for which a specific problem has been identified or which are of questionable quality and should be analyzed with caution. These include, in the respondent file, the date the respondent last attended regular school, pregnancies ending in induced abortion, date of first sexual intercourse, and date and age when the respondent used any method of contraception for the first time, and in the interval file, the date the pregnancy ended, the duration of the pregnancy, and the date the pregnancy began. Date the respondent last attended regular school. TL 95-99. If the respondent was still attending school at the time of the interview, the interviewer was supposed to code this item 99696. Some interviewers entered the date of the interview instead. Thus, the code 99696 will not identify all respondents who are still attending school. Pregnancies ending in induced abortion. TL 163-164. As in the past in surveys of this kind, abortions were under-reported by NSFG respondents. The number of induced abortions in 1981-85, (the most recent 5-year period for which comparable data are available), represents about 41 percent of the number reported for that period by the Alan Guttmacher Institute (AGI), and about 49 percent of the number reported for that period by the Centers for Disease Control (CDC). Under-reporting is more severe among non-white women than white women. The AGI and CDC data come from providers of abortions services, including public and private hospitals, clinics, and private physicians. The reporting of abortions may be less complete in Cycle IV than in Cycle III. For Cycle III, the number of abortions reported in the NSFG for the five years before the survey was 47 percent of the number reported by AGI, compared with 41 percent for 1981-85 for Cycle IV. With due allowance for sampling variability, estimates of numbers of live births, miscarriages, and stillbirths correspond fairly well to information from other data sources. It appears that rather than misreporting pregnancy outcomes, the majority of the abortion under-reporting is the result of women not reporting at all pregnancies that ended in abortions. Date of first sexual intercourse, TL 338-342. and date of first sexual intercourse after first menstrual period. TL 383-387. Date of first sexual intercourse and date of first sexual intercourse after first menstrual period were determined by asking the respondent for the date (C-6 or C-9), for her age at the time (C-7 or C-l0), and whether it was before or after that birthday (C-8 or C-11) (to be sure that she wasn't rounding her age to her next birthday). For a great many respondents, these three pieces of information were inconsistent. The following decision rules were used to force the three items to be consistent: 1. Check: (a) the date of first conception (either coded directly in C-18, or calculated as the date the first pregnancy ended (B-l4) minus the duration of pregnancy (B-15); and (b) the earlier of the date of first marriage or first cohabitation (F- 15, F-17, F-19, F-21, F-28, F-31). 2. If any of these are inconsistent with (i.e. earlier than) the reported date or age at first intercourse, but not both, keep the consistent entry and edit the inconsistent entry or entries to be consistent with it. (In editing dates to agree with ages, keep month or season and change year.) 3. If the earliest date (from 1 above) is inconsistent with (i.e. earlier than) both age and date, change C-6, C-7, and C-8 (or C-9, C-10, and C-11) to missing (9) for later imputation. 4. If C-6, C-7 and C-8 (or C-9, C-10, and C-11) are inconsistent with each other and it is not possible to tell which is correct and which is incorrect--for example, if the dates of marriage, cohabitation, and pregnancy are blank, or are after both the reported age and date of first intercourse: (a) if C-6 and C-7 (or C-9 and C-10) are in agreement, edit C-8 (C11) to agree. For example, if the date in C-6 suggests that R was 20, and the age in C-7 says that she was 20, but C-8 says that it was "before" her 20th birthday, change C-8 to "after." (b) if C-6 (C-9) does not agree with either C-7 (C10) alone or C-7 as modified by C-8 (C-11), then adjust the date to agree with the age. For example, if the age calculated from C-6 is 20, and C-7 is 21, and C-8 is "after," then change the date in C-6 to agree with 21. The coders were told that if they thought that these rules would cause them to code C-6 to C-8 (C-9 to C11) incorrectly, they were to refer the case to NCHS. Date and age when the respondent used any method of contraception for the first time. TL 542-546 (date) and TL 547-548 (age). These two items have a great deal of missing data. It appears that many respondents misunderstood these two questions. In many cases the respondent gave an answer that was inconsistent with other information she had given, so her answer was recoded to missing. Date the pregnancy ended. TL 21-25; duration of the pregnancy. TL 28-29; and date the pregnancy began. TL 289-293. Logically, the date a pregnancy began plus the duration of the pregnancy should equal the date the pregnancy ended. For many respondents, this relationship does not hold among the the three variables. These variables have not been forced to be consistent. The date the pregnancy ended and the duration of pregnancy were assumed to be the more accurately reported items, and so these two variables were used to create related recodes. Omitted Items Reproductive health is one of the broad areas of inquiry addressed by the National Survey of Family Growth. In 1988, with the growing concern over the spread of HIV infection, the need for more detailed, population-based data on sexual behaviors affecting the epidemiology of sexually transmitted diseases and HIV infection became compelling. The NSFG expanded its inquiry in these areas, recognizing also the benefits this expansion would bring to other critical areas of analysis of the NSFG data. This step also greatly increased the sensitivity of the survey with respect to any possible disclosures of the information relating to individual survey respondents. Keenly aware of its responsibilities to protect the confidentiality of the personal data which respondents have voluntarily entrusted to it, the National Center for Health Statistics has deemed it necessary and prudent to withhold certain items collected in Cycle IV of the NSFG from public use data tapes that are made generally available for research and training uses. The items withheld are noted on the tape documentation. They include data on number of sexual partners, self-perceived risk of contracting an STD or HIV infection, having contracted or received treatment for such an infection, frequency of sexual intercourse, changes in sexual behavior to avoid infections, and use of illicit drugs during one's most recent pregnancy. The inclusion of these highly personal data would create a heightened probability of mischievous or inadvertent disclosure. While these items will not be made generally available on micro- data tapes, the National Center for Health Statistics wishes to promote the scientific purposes for which the data were collected. To this end, the Center could make the data available to researchers for specified scientific analyses, under special arrangements that assure confidentiality and protection of the data commensurable with that provided by the Center itself. Sample Design, Estimation Procedures, and Variance Estimation The following summary briefly describes the sample design, weighting, and variance estimation for the NSFG, Cycle IV. The summary was taken from a forthcoming report from the National Center for Health Statistics, National Survey of Family Growth. Cycle IV: Sample design, weighting, imputation, and variance estimation. More complete information on the imputation procedure used in Cycle IV can be found in that report. The report will not be published before fall 1990. See page 7 for information on how to obtain a copy. Sample design. The 8450 women interviewed for the NSFG, Cycle IV, were drawn from households in which someone had been interviewed for another NCHS survey, the National Health Interview Survey, or NHIS, between October of 1985, and March of 1987. If the woman selected for the NSFG had moved since the NHIS interview, she was followed, or tracked, to her new address, and interviewed there. Different numbers of women were available in the NHIS in 1985, 1986, and 1987, so the sampling procedure differed somewhat in each of these years. The NSFG sampling plan was designed to (1) select more black women than would have fallen into the sample by chance, in order to increase the reliability of the data for black women; and (2) increase the reliability of the data for nonblack women by reducing the variations in the sampling rates for nonblack women. The NSFG sampled only one woman per household, even if more than one eligible woman lived there. The NSFG selected households in the following way: for the entire period (December 1985-March 1987), all NHIS sample households containing one or more eligible black women but no non-black women were selected; some other sample households were selected as described in the report. A simple random sample of women 15-44 in the U.S. would mean that every woman 15-44 would have the same chance of being selected for the sample--regardless of where she lived or what her characteristics were. The NSFG sample is not a simple random sample for two reasons: (1) only some areas were selected to be in the sample, while other areas were not; and (2) within areas included in the sample, women were sampled at different rates. For example, black women were sampled for the NSFG at a higher rate than other women, so that reliable statistics could be produced for black women. As a result, interviews were completed with 2771 black women and 5679 women of other races. Certain other women (described in the report) were also sampled at higher rates. Therefore the NSFG data must be weighted, and estimates of sampling errors should be made using the techniques discussed below. The response rate to the NHIS, on which the NSFG was based, was 96 percent. Of the sampled women selected from responding NHIS households for the NSFG, the simple response rate to the NSFG was 80 percent. However this simple response rate does not take into account the subsampling for nonresponse (described in the report) which was a part of the intensive followup--the last stage of interviewing. NCHS prefers to take this subsampling into account when calculating the response rates. When this is taken into account, the response rate to the NSFG was 82 percent of the women in the NHIS. Thus, the total response rate is 96 percent times 82 percent, or about 79 percent. Weighting.--The NSFG is intended to produce national estimates of the number, as well as the percentage, of women with certain characteristics--such as the number using the pill, the number infertile, or the number who used family planning services in the last year. In order to produce these national estimates, each woman interviewed was given a sampling weight, which is the number of women in the population that she represents. The weights were made in 4 main steps: the first is the baseweight, which is the reciprocal of the probability that the woman was selected for the sample. For example, if the probability that a certain woman was selected was 1 out of 6000, her baseweight would be 6000. The second stage of weighting was trimming; cases with very large weights were reduced to a maximum value. The third stage of weighting was an adjustment for nonresponse. Certain categories of women were less likely than others to be found at home and interviewed, so adjustment for nonresponse attempts to correct for this. The fourth stage is called post- stratification; this is adjusting the NSFG totals to a known number of women by age, race, marital status, and parity (the number of live births the woman has had) obtained from the U.S. Bureau of the Census. The preliminary weights as well as the final post-stratified weight appear on the Public Use Tape in TL 2540-2574 in the Respondent file and TL 338-372 in the Interval file. Variance estimation.--Variance is a measure of how much a statistic (such as a percent or an average) can vary in different samples. In a simple random sample, the probability that a person will be selected for the sample is the same for all persons in the population. However, the NSFC- (and the NHIS, on which the NSFG was based) was not based on a simple random sample; the probabilities of selection varied by area, by race and by other variables. Therefore, variance estimates in many standard computer packages and many statistics textbooks will be too small when applied to the NSFG. We recommend that researchers use the weights, variance formulas, and variance estimation techniques described here to estimate sampling errors for the NSFG. NSFG variances were estimated using a technique called Balanced Repeated Replication. This procedure estimates the standard error for survey estimates (such as percentages or numbers) using parts of the whole sample. In the NSFG, tables were designed using a number of dependent and independent variables. Sampling errors were calculated for the weighted numbers in these tables. The ratios of the variance to the square of the weighted number were plotted against the inverse of the weighted number, and a weighted least-squares line was fit to those points. The intercept and slope for these lines are given in Appendix 6; they can be used to estimate the standard errors of percentages and weighted numbers from the NSFG. If researchers wish to estimate variances for other statistics, such as averages or regression coefficients, they can use balanced repeated replication, as described in the detailed report from which this summary was taken. The 100 replicate weights necessary for such estimates appear in TL 2754-3553 of both the Respondent and Interval files.KEY TO DOCUMENTATION The following sections document the contents of the Respondent and the Interval files. The first part of each section consists of an index listing the questionnaire items and the recedes along with the tape location for each item. The list of recodes also shows the tape location of the imputation flag for that recode, and a mnemonic variable label. The second part of each section is the documentation of the tape contents. The documentation of the tape contents is adapted from the documentation of the original data file supplied by Westat, Inc., the fieldwork contractor. The data were originally keypunched in a record and column format, and the record and column numbers have been retained in the documentation; the original record number is shown in the upper right-hand corner of each page, and the original column numbers are shown in parentheses underneath the tape location. For each item, the documentation includes the question name or number, the text of the question, the numerical categories into which responses were coded, and detailed category descriptions. The documentation also shows the numbers of respondents in each response category, separately for black women, white women, other women, and women of all races combined. These marginal distributions are raw unweighted counts of sample women or pregnancy intervals; they are not estimates of numbers or distributions for the population represented by the sample. To make such estimates, sample cases must be weighted. The unweighted marginal distributions are provided only as a guide to the analyst, who often wants to know in advance if the number of cases in a particular category is large enough to sustain a particular type of analysis.RECORD LAYOUT Respondent File Index - Questionnaire Items by Tape Location Tape Locations 1-23 Respondent file index List of questionnaire items by tape location TAPE

specifications used to create the recoded variables. Each specification describes how the original data items were combined to create the recodes. The original data items are usually referred to by the original record/column location (e.g 2/17-18), rather than by their tape location on the Public Use Tape. During data processing, the data were keypunched on 33 records with a maximum of 120 columns per record. The original record number appears in this Tape Documentation in the upper right-hand corner of each page and the original column number(s) appear in parent underneath the tape location. Unless otherwise specified, age variables are calculated as the century month of the event minus the century month of birth, divided by 12. Four column age variables have an implied demical after the second column. If an analyst prefers to use age in completed years, the first two columns of the variable should be used. The four column age variable should be used for computing mean ages. Two-column age variables refer to age in completed years. Sometimes a number of related variables (such as ever-use of specific contraceptive methods) are created in exactly the same way, so their specifications differ only in the tape location from which the original data were taken. To avoid repetition, the specifications for one variable in the group is included, followed by a list of the other variables in the group. Recode specifications appear in the same order the variables appear on the Public Use Tape.

If the respondent has had a live birth and has never been formally married (VAR976 coded blank), the birth occurred before marriage, so FMARBABY = 888. VAR415 "Int Btwn 1st Live Birth & 2nd Live Birth/Interview Date" VAR415 "Interval between first live birth and second live birth or interview date" (BABY12) If the respondent has never had a live birth (o4/87-88 coded 00), then there is no interval from first ot second live birth, so BABY12=BLANK. If the respondent had at least two pregnancies ending in live birth (04/87-88 coded 02-20), then the interval between the first and second live birth is the century month of the second pregnancy ending in live birth (BABY2MO, defined similarly as BABY1MO) minus the century month of the first pregnancy ending in live birth (BABY1MO, see recode 410). If the respondent has had only one pregnancy ending in live birth (04/87-88 coded 01), then the interval is the century month of interview (03/25-30) minus the century month of the first pregnancy ending in live birth (BABY1MO).

If R has had 1 or nore pregnancies (05/85-86 coded 01 to 25), and is ever formally married (VAR976 ne blank), then calculate FMAR1CON as the date of conception of first pregnancy (which must be calculated as described below), minus the date of first formal narriage (VAR976). To calculate the date of first conception, use interval file data for the first pregnancy (06/13-l4 = 01): If there is a date of conception in 10/89-92 (i.e. the date of conception is not missing or estimated), use it. If not: date of conception=date pregnancy ended (06/23-28) minus duration of pregnancy in months (PRGLNGHT). If the interval is a negative number, the first conception occurred before marriage and FMAR1CON is coded 995. If the respondent is ever-married (VAR76 ne blank), but has never haen pregnant (05/85-86 eq 00), then FMAR1CON eq the interview date (03/25-30) minus the date of her first marriage (VAR976).

VAR112 "Method Used at Last Intercourse, If Any" (LASTBC) VAR112 "Method Used at Last Intercourse, if any" (LASTBC) If R has never had intercourse since first period (17/56 coded 2), then LASTBC-BLANK. If R has never used a method (11/129 coded 2), then LASTBC=995. If R did not use a method at last intercourse (12/65 coded 2), then LASTBC=996. If 12/64=3 (no intercourse after first time), then the code for LASTBC = code for SEX1MTHD. If R did use a method at last intercourse (12/64 coded 1 or12/65 coded 1), then: if R's method was female sterilization (12/64 coded 1) then LASTBC=010. if R's method was reported in C-45 (12/66-68), use the code in 12/66-68. Convert combination codes to single method codes in the same way as shown in VAR110. VAR115 "First Method Ever Used" (METHOD1) VAR115 "First method ever used" (METHOD1) If R has never used a method(11/129 coded 2), or never had intercourse since first period (17/56=2), then mathod1 is inapplicable, or BLANK. If R has used 2 or more methods(12/50 coded 2), then her first method ever used is the method in C-41 (12/52-54). If R has used only 1 method (12/50 coded 1), then the only method ever used is the first method ever used (either in 12/18-49 or in 12/74-89; OR take the only code "1" in VAR120 to VAR148). Convert combination methods to single method codes as in VAR110 (SEX1MTHD). VAR118 "Month & Yr R Used 1st Method for 1st Time" (DATEUSE1) VAR118 "Month and Year R used first method for the first time" (DATEUSE1) NOTE: This will be a 5-column field. The first column is "9" if the month is estimated from 12/57, the age, or age range, and zero otherwise. Convert seasons to months. If R has never had intercourse since first period (17/56 coded 2), or has never used a method (11/129 coded 2), then DATEUSE1=blank. If R has used a method, and if she used her first method at her first intercourse (12/57=1), then use the date in DATEUSE1 = DATEUSE1 (VAR540). If used her first mehtod within a month of her first intercourse (12/57=2), use the data 12/58-61; if no date is given in 12/58-61, use the date in DATESEX1. If she used her first method one or more months after first intercourse (12/57=3-6), and her month and year of first use are not missing (12/58-61 NE 9797, 9898, or 9999), then use the date in 12/58-61. If R did not report a month and year in 12/58-61, but did report an interval after first intercourse, (12/57=3-6), then: DATESEX1 (VAR540) plus the midpoint of the interval is the estimated date of first use. The midpoints of the intervals are estimated by: 1-3 months after intercourse = 2 months 4-6 months after intercourse = 5 months 7-12 months after intercourse = 10 months More than 12 months after intercourse = 18 months If R has used a method (11/129=1 or 11/127=2), and she gave a time interval after first intercourse when she used her first method (12,57=2-6) but the month and year of first method use is before the date of first intercourse (DATEUSE1 Less than DATESEX1), then DATEUSE1 is estimated using the midpoint of the time interval in 12/57. If R has used a method (ANTMTHD=1) and C-43=3-6 (TL541), but the month and year of first method use is before or the same as the date of first intercourse (DATEUSE1 LE DATESEX1), then change DATEUSE1 to DATESEX1 plus the midpoint of the interval reported in C-43, TL541 (For example, if C-43=3, then DATEUSET1 = DATESEX1 + 2 months, if C-43=4, then DATEUSE1= DATESEX1 + 5 months, etc.) If data are missing, code DATEUSE1 = 9999 and impute. VAR120 "Ever Used Pill" (PILL) VAR120 "Ever used pill" (PILL) If the respondent has never had intercourse or never had intercourse since first period (17/56=2), then ever-use is inapplicable, so PILL=blank. If the respondent has ever used the pill for a month or more(12/81 coded 1) or at all(12/32-33=08) or if it was her first method ever (12/52-54=008, or 046-058, or 846-858) she has ever used the pill, so PILL=1. If the respondent has never used the pill(12/81 coded 2 AND 12/32-33 coded 00 or blank AND 12/52-54 NOT coded 008 or 046-058 or 846-858) then PILL=2. If R never had intercourse after the first time (12/64 coded 3), or either never used a method (11/129 coded 2), or did not use the pill (12/32-33 coded blank or 00), then PILL = 2.

VAR122 "Ever Used Condom Without Foam" (CONDOM4) VAR122 "Ever used condom without foam" (CONDOM4) If the respondent has never had intercourse or never had intercourse since first period, (17/56=2), then ever-use is inapplicable, so CONDCOM4=blank. If R has used the condom (without foam) for a month or more (12/74=1), or at all (12/18-19=01), or if condom alone was her first method ever (12/52-54=001, 092-100, 892-900), then she has ever used the condom, so CONDOM4=1. If the R has never used the condom (12/74=2 AND 12/18-19=00 or blank AND 12/52-54 NE 001, 092-100, or 892-900) then CONDOM4=2. If R never had intercourse after the first time (12/64 coded 3) or never used a method (11/129 coded 2), or did not use condom (12/18-19=00 or blank), then CONDOM4=2. VAR123 "Ever Used Condom and Foam Together" (CONFOAM) VAR123 "Ever used condom and foam together" (CONFOAM) If R has never had intercourse or never had intercourse since first period (17/56=2), then ever-use is inapplicable, so CONFOAM = blank. If R has used condom and foam together (12/75=1 or 12/20-21=02), or if condom and foam was her first method ever (12/52-54=002, 082-091, 882-891), then she has ever used condom and foam together, so CONFOAM=1.

(2) If R has ever had intercourse (SEXEVER=1): (a)and if C-10 (09/121-122) is not blank or missing, use the age in 09/121-122, and go to step 3. (b)and if C-10 (09/121-122) is blank, and if C-7 (09/108-109) is not blank or missing, use the age in 09/108-109, and go to step 3. (3) If 09/113=2 (or 09/126=2), use the age as shown. If 09/113=1 (or 09/126=1), subtract 1 year from the age. (4) If R's age is missing (09/121-122=97,98,or 99, or 09/121-122= blank and 09/108-109=97,98, or 99), and if R reports an age range in 09/123-125 or 09/110-112, use the procedure in step 5 of VAR540. VAR304 "Want or Intend Another Birth" (WANTKID1) VAR304 "Want or intend another birth" (WANTKID1) Categories should be tested in the order listed here. If the respondent (or husband) is surgica1ly sterile (15/19=1), use 16/79; If the respondent's periods have not started yet (16/102=1), use 17/24; If the respondent is nonsurgically sterile for other reasons (D-14=01=03 or 05-07), use 16/107; If the respondent intends to have a sterilization operation or abortion for health reasons (17/18=1 or 17/20=1 or 17/21=1), use 17/22; Otherwise use 17/37 if R is currently pregnant, and 17/24 if R is not currently pregnant. If A would NOT like to have another child even thongh it is unlikely or impossible that she can (16/79 or 16/107 or 17/22=2), WANTKID1=1. If R does NOT intend to have another child or disagrees with husband about it (17/24 or 17/37=2 or 3), then WANTKID1=2. If R would like to have a child or another child even though it is unlikely or impossible that she can (16/79 or 16/107 or 17/22=1), then WANTKID1=3. If R intends to have a baby or another baby (17/24 or 17/37=1), then WANTKID1=4. If R says she doesn't know if she wants to have a child or that it is up to God (16/79 or 16/107 or 17/22=8 or 17/24 or 17/37=8), then WANTKID1=5. If 16/79 or 16/107 or 17/22 or 17/24 or 17/37=7 or 9, then code WANTKID1 = 9 and inpute. If any item = 7 or 9, then code WANTKID1 = 9 and impute. Code categories: 1 = No, would not like 2 = No, does not intend 3 = Yes, would like 4 = Yes, intends 5 = Yes (DK, up to God) The percent wanting nore = 3-5/1-5. VAR305 "Collapsed WANTKID" (WANTKID2) VAR305 "Collapsed WANTKID" (WANTKID2) If WANTKID1=1 or 2, the R does NOT want a baby or another baby, so WANTKID2=1. If WANTKID1=3, 4, or 5, the R DOES want a baby or another baby, so WANTKID2=2. Missing data: if WANTKID1=9, then code WANTKID2 = 9 and impute. 4VAR309 "Number of Months Infertile" (INFERT) VAR309 "Number of months infertile" (INFERT) NOTE: This value is used to create variable 310. If the respodent is not currently married or not infertile (INFERT not equal to 2 or 9), then NINFERT=blank. If the respondent is currently married or cohabiting and infertile (INFERT coded 2), then NINFERT is the number of months that the couple has been infertile--that is, the number of months they have been continuously married, have not used any contraception, and did not become pregnant. Thus, NINFERT is calculated, for infertile respondents only, by taking the difference, in months, between: current marriage or cohabitation and interview, last method use and interview, and last pregnancy termination and interview. The smallest of these values will be the number of months infertile. The range will be 12 to 360. If 16/84=1 or 16/85=1, subtract date of sterility in D-15 (16/103-106) from the date of interview (R-7) to obtain the number of months infertile. Note: Do not count periods of cohabitation before formal marriage, if R cohabited and then married. VAR310 "Infertility Status" (INFERT) VAR310 "Infertility status" (INFERT) (1) If the respondent is never married or formerly married, (03/36=3-6) then infertility is not applicable, so INFERT=BLANK. (2) If the respondent or her husband/partner is surgically sterile (15/19 coded 1), then the couple is surgically sterile, so INFERT=1. (3) If R reports that she and/or her husband/partner are sterile for nonsurgical reasons (16/84 or 16/85 or 16/87 coded 2), or she has never had a menstrual period (16/94-95=04), then the couple is infertile, so INFERT=2. (4) If R is currently pregnant (05/91=1), then she is fecund, so INFERT=3. (5) If the respondent has used a method in the open interval (11/67 coded 1), and if she is still using it (11/77 or 11/90 or 11/103 or 11/116=1 or 11/78-81=9696 or 11/91-94=9696 or 11/104-107=9696), then R is fecund, so INFERT=3. (6) If, during the 12 months or more of continuous marriage the couple did not have a pregnancy and used no contraception, they are classified as infertile. (Respondents classified as infertile will have a number of months infertile, from 12 months to 360. The number of months will be stored in VAR309, NINFERT). That is, (a)If R has been in her current marriage or union for 12 months or more (R-7 minus F-15 or F-28 GE 12 or F-29 GT 11), continue with step 6b. (b)If the case has not yet been classified (R is not pregnant, surgically sterile, or currently using, and has been married or cohabiting, at least 12 months), determine which of the following 4 groups R is in: (1)If R is never pregnant (05/85-86=00), and never used a method (since first intercourse; 11/67=2), then R is infertile, so INFERT=2. (2)If R is never pregnant (05/85-86=00) and ever used a method since first intercourse (11/67=1): If R's date of interview MINUS the date of her last contraceptive use is 12 months or more (R-7 MINUS the last stop use date in 11/117-120, 11/104-107, 11/91-94, or 11/78-81 GE 12 months), then R is infertile, so INFERT=2. (3) If R is ever pregnant (05/85-86=01-30) and ever used a method since last pregnancy (11/67=2): If R's date of interview MINUS the ending date of her last pregnancy is 12 months or more (06/80=1 AND (R-7 MINUS B-14 GE 12)), then R is infertile, so INFERT=2. (4) If R is ever pregnant (05/85-86=01-30) and ever used a method since last pregnancy (11/67=1): (aa) If R~s date of interview MINUS the ending date of her last pregnancy is 12 months or more ((06/80=1 AND (R-7 MINUS B-14 GE 12)), then continue with step 4bb. (bb) If R's date of interview MINUS the date of her last contraceptive use is 12 months or more (R-7 MINUS the last stop use date in 11/117-120, 11/104-107, 11/91-94, or 11/78-81 is GE 12 months), then R is infertile, INFERT=2. (7) If missing data made a case bypass these tests, then: (a) If R is currently married (03/36 coded 1 or 2) and is not surgically sterile (15/19=2 or blank), and is currently using a nonsurgica1 method (CONSTAT = 03-16 or the method calendar for the month of interview shows a method use code other than sterilization (001-010, 012, 013, 015, 016, 046-136, 846-936), or a current pregnancy (300), then R is fecund, INFERT=3. (b) If R is living with a partner (03/36=2) and the date she began living together is missing (23/96-99=9999) and the length of living together is missing (23/100-102=997, 998, or 999) and her ability to have children is unknown (16/84 or 16/85= 8 or 9) and her method calendar does not show contraceptive use (METHCAL=0000,9999, or 5000), then code R as fecund, INFERT=3. If there is too much missing data to classify the respondent, code INFERT = 9. The case will be examined by NCHS staff and imputed if necessary. (8) All other cases are fecund, INFERT=3 NOTE: These specs include informally married, or cohabiting, women (03/36=2) as married. To maintain comparability with cycle 3 (1982) results, INFORMALLY MARRIED (COHABITING) WOMEN MUST BE EXCLUDED. SEE SPECS FOR VAR309 (NINFERT). VAR320 "Type of Sterilization Operation" (STRLOPER) VAR320 "Type of sterilization operation" (STRLOPER) If the respondent or her current husband/partner has not been surgically sterilized (15/19 coded 2 or blank, then STRLOPER=5, not surgically sterilized. If there is only one operation coded (15/23 coded 1 or 15/53 coded 2 or 15/83 coded 3 or 16/18 coded 4 or 16/48 coded 5 only), then: If Tubal ligation (15/53 coded 2), STRLOPER=1. If Hysterectomy (15/83 coded 3), STRLOPER=2. If Vasectomy (16/18 coded 4), STRLOPER=3 If Other or unknown type (15/23 coded 1 or 16/48 coded 5) or (15/19 coded 1 and 15/23 or 15/53 or 15/83 or 16/18 or 16/48 coded 7,8, or 9), then STRLOPER=4. If there are two or more operations coded in D-2 then: If there is a male operation (16/18 coded 4) AND a female operation (15/23=1 or 15/53=2 or 15/83=3 or 16/48=5) coded, then use the female operation if the reasons (D-5 and D-6) are known; if the reasons for one operation are known and the reasons for the other operation are missing, use the operation for which the reasons are known. If there are 2 female operations or 2 male operations, then classify the respondent according to the earlier operation (compare the dates in D-3) if both dates are known. If the date of one operation is missing and the date of the other operation is known, classify R using the operation for which the date is known. VAR360 "Fecundity Status" VAR360 "Fecundity status" If it is impossible for the respondent or her current husband or partner to have a (nother) baby because of a sterilizing operation that was done for contraceptive reasons: If the number of operations coded in D-2 is one, AND If 15/19 is coded 1 AND one of the following: (first mention in D-5 NE 80-89 and NE 96,97,98, or 99 AND D-6=96) or D-6=01-07 and D-6 NE 08; or D-6=01-07 and D-6=08 and first mention in D-5 NE 80-89) then she is contraceptively sterile, so FECUND=1. If the woman or couple have had more than one sterilizing operation (coded in D-2): if one is a female and the other is a male operation, classify using the female operation if the reasons (D-5) and D-6) for both operations are known; if the reasons for one are known, and the reasons for the other are missing, use the operation for which the reasons are known. if both are female, or both are male, classify using the earlier operation if both dates are known; if one date is missing and the other date is not missing, use the operation for which the date is known. If it is impossible for the respondent or her current husband to have a (nother) baby because of a sterilizing operation that was done for noncontraceptive reasons (15/19 is coded 1 AND first mention in D-5=80-89 or 96 AND D-6=96; or D-6=08 or 96 ONLY, or D-6=08 and 01-07, and first mention in D-5=80=89), then she is surgical1y sterile for noncontraceptive reasons, so FECUND=2. If 15/19=1 AND D-6=97,98, or 99 for the only operation, or for the operation which should be used to classify the case: and if D-2=2 or 4, then FECUND=1 and if D-2=1,3, or 5, then FECUND=2. If it is impossible for the respondent to have a(nother) baby for reasons other than surgical sterilization (16/84=2 or 16/85=2 or 16/87=2), then she is nonsurgically sterile, so FECUND=3. If she reports that it is difficult for her, and/or her current husband, to conceive or deliver a(nother) baby (16/108 coded 1), or a medical doctor advised her never to become pregnant (again) and said it would be dangerous for her and/or the baby and she will have an operation to be sure she won't become pregnant (17/18 coded 1), or her husband or partner will have an operation (17/20 coded 1), or if she becomes pregnant (again) she will have the pregnancy ended (17/21 coded 1), then she is subfecund, so FECUND = 4. If the respondent has used a method in the open interval (11/67 coded 1), and she is still using it (11/77 or 11/90 or 11/103 or 11/116 coded 1 or 11/78-81=9696 or 11/91-94=9696 or 11/98-101=9696), then R is fecund, so FECUND = 6. If, during the 36 months or more of continuous marriage or cohabitation the couple did not have a pregnancy and used no contraception, she is classified as having a long interval. That is: (a) If the interval between the date of interview and the date of the current marriage or cohabitation is 36 months or more** (R-7 minus F-15 or F-28 GE 36), continue with step 7b. (b) If the case has not yet been classified, determine which of the following 4 groups R is in: (1) Never pregnant (05/85-86=00), and never used a method since first intercourse (11/67=2), then R has a long interval (FECUND=5). (2) Never pregnant (05/85-86=00) and ever used a method since first intercourse (11/67=1): If R's date of interview MINUS the date of her last contraceptive use is 36 months or more (R-7 MINUS the last stop use date in 11/117-120, 11/104-107, 11/91-94, or 11/78-81 GE 36 months-- choose the location by finding 11/76, 11/89, 11/102, or 11/115=2), then R has a long interval, so FECUND=5. (3) Ever pregnant (05/85-86=01-30) and never used a method since last pregnancy (11/67=2): **(R-7 minus F-15) GE 36; or (R-7 minus F-28) GE 36 If R's date of interview MINUS the ending date of her last pregnancy is 36 months or more (06/80=1 AND (R-7 MINUS B-14 GE 36)), then R is infertile, so FECUND=5. Otherwise, R is fecund (FECUND=6). (4) Ever pregnant (05/85-86=01-30) and ever used a method since last pregnancy (11/67=1): (aa) If R's date of interview MINUS the date of her last pregnancy is 36 months or more ((06/80=1 AND (28/47-52 MINUS 06/23-28 IF 06/80=1)), then continue with step 7b4bb. (bb) If R's date of interview MINUS the date of her last contraceptive use is 36 months or more (R-7 MINUS the last stop use date in 11/117-120, 11/104-107, 1l/91-94 or 11/78-81 is GE 36 months), then R has a long interval, so FECUND=5. If R is not surgically sterile (15/19 coded 2 or blank), and is currently using a nonsurgical method of contraception (CONSTAT = 03-17 OR the method calendar for the month of interview shows a method use code other than sterilization, or a current pregnancy or nonitercourse ((0010-0100, 0120, 0130, 0150, 0160, 0460-1360, 3000, 5000, 8460=9360)), then R is fecund, so FECUND=6. If D-1=2, D-11 NE 2, D-13 NE 2, AND D-17 NE 1, then R is Fecund (code 6), even if there is missing data on D-19,21,22, or 23. If R has never been pregnant, never been married, and D-13-8 or 9 or D-17=8 or 9, and Method Calendar=9's, then R is fecund (code 6). If R is not married (03/36=3-6) and not havimg intercourse or never had intercourse (CONSTAT=31 or 30), AND 16/84 or 16/85 or 16/87, or 16/108=8, then FECUND=6. 3 cases: If ability to have children is not ascertained and R is married or cohabiting (D-11 and D-12=9), and CONSTAT=31 (nonuser, no sex in last 3 months), code FECUND=6 (fecund). If R still has not been assigned a code, then the case is assigned a value after looking at a printout of the entire case. If there was no useful information, then code FECUND = 9 and impute. VAR380 "Nonintercourse in the Last 12 Months" (NOSEX12) VAR380 "Nonintercourse in the last 12 months" (NOSEX12) If R never had intercourse, or never had intercourse since first menstrual period (17/56 coded 2), then NOSEX12=96. If R had intercourse only once (11/18-21=9595), then the number of months of nonintercourse is the date of interview (28/47-52) MINUS DATESEX1 (range=0-12) If R has had no periods of nonintercourse (11/18-21=9696) then NOSEX12=00. If R is never pregnant, use 11/18-41. If R is ever pregnant, use 11/43-66 for the open interval and 10/20-43 for each of the closed intervals ending in the last 12 months. If any of the months of nonintercourse (10/20-43 OR 11/18-41 OR 11/43-66) fall within the last 12 months -- that is, the date of the interview (28/47-52) MINUS the ending date of the period of nonintercourse, is less than or equal to 12 months, then NOSEX12 is the NUMBER OF MONTHS within the last 12 months, that the respondent did not have intercourse at all. Code categories: 96 = Never had intercourse 0-12 = Number of months of nonintercourse VAR382 "Nonintercourse in the Last 36 Months" (NOSEX36) VAR382 "Nonintercourse in the last 36 months" (NOSEX36) Repeat specifications for VAR80, but use the last 36 months, rather than the last 12 months. Code categories: 96 = Never had intercourse 00-36 = Nusber of months of nonintercourse 4VAR385 "Duration of Current Period of Nonintercourse" (NOSEXDUR) VAR385 "Duration of the current period of nonintercourse (NOSEXDUR) If R has never had intercourse or never had intercourse since first period (17/56 coded 2), then NOSEXDUR = blank. If R had no intercourse after the first time (11/18-21 coded 9595), then NOSEXDUR = the date of interview (14/122-125) minus the date of first intercourse (VAR540). If R is currently having intercourse (11/68 coded 2; or 10/19 and 11/42 coded 2 or blank and 11/18-19 coded 96, or the ending date of the last period of nonintercourse in 10/20-43, 11/18-41, or 11/43-66 is less than the date of interview), then NOSEXDUR=996. For all other R's (11/68 coded 1), the beginning and ending dates of the current period of nonintercourse are in the last non-blank entry 11/18-41, 11/43-66, or 10/20-43. NOSEXDUR = the date of interview (14/22-25) minus the start date for the last non-blank entry 11/18-41, 11/43-66, or 10/20-43. VAR420 "Central Number of Additional Births Expected" (ADDEXP) VAR420 "Central number of additional births expected" (ADDEXP) If R is not currently pregnant (05/91 coded 2): If R does not intend to have more children (17/24 coded 2), or the questions are inapplicable (17/24 coded blank), then R's additional number expected is zero, so ADDEXP=000. If 17/24=3 or 8 and 17/28-29=00 and 17/30-31=blank, then ADDEXP=000. If R intends more (17/24 coded 1), and she gives an intended numher in D-26, then ADDEXP = 10 times the number in 17/25-26. If R did not give an intended number (17/24 coded 3 or 8 or 17/25-26 coded 98), but did give a largest and smallest number (17/28-29 and 17/30-31 NE 97,98, or 99), then ADDEXP is the average of the largest and smallest number expected; i.e., 10 times ((17/28-29) + (17/30-31) /2). If 17/28-29 or 17/30-31 = 97,93, or 99, then code ADDEXP = 999 and impute. If R is currently pregnant (05/91 coded 1), add 1 child (times 10) to her additional number expected, and use 17/37-44 to find ADDEXP: If R does not intend to have more children after her current pregnancy (17/37 coded 2), then ADDEXP = 010. If 17/37=3 or 8, and 17/41-42=00, and 17/42-43=blank, then ADDEXP=010. If R intends more after her current pregnancy (17/37 coded 1), then ADDEXP = (10) times ((17/38-39) + (1)). If R did not give an intended number (17/37 coded 3 or 8 or 17/38-39 coded 98) but did give a largest and smallest, then ADDEXP = the average of the largest and smallest number expected, plus one for the current pregnancy, so ADDEXP = 10 times ((17/41-42)+(17/43-44) / 2) +1). If the largest or smallest number expected is not known (17/41-42 or 17/43-44 coded 97,98,99), then code ADDEXP = 999 and impute. If R gave a range in D-33 (17/38-39 coded 96), then ADDEXP is the average of the range, plus 1 for the current pregnancy, times 10: ADDEXP = 10 times ((17/69-70) + (17/71-72) / 2) + 1. If D-28 (largest) is a number, but D-29 (smallest) is 97, 98, or 99, use (largest) minus (1 child) = smallest, to compute ADDEXP: ((17/28-29) - 1) * 10 = ADDEXP. If R reported a range in D-26 (17/25-26 coded 96), then ADDEXP is the average of the range: ADDEXP = 10 tines (17/57-58 + 17/59-60 / 2). VAR985 "Intentions for Additional Births" (INTENT) VAR985 "Intentions for additional births" (INTENT) NOTE: For currently pregnant women INTEN refers to intentions after the current pregnancy. If 17/24 or 17/37 is coded 7 or 9, then code INTENT = 9 and impute. If the respondent is sterile, or subfecund and intends an operation or abortion if she does become pregnant again (17/24 coded blank AND 17/23 coded 2 or blank)*, OR if R says that she does not intend to have a(nother) baby (17/24 ooded 2 or 17/37 coded 2), then she does not intend to have a(nother) baby, so INTENT=2. If R says she intends to have a(nother) baby (17/24 or 17/37 coded 1), then she does intend (more) children, so INTENT=1. If R said that she didn't know, it was to God, etc. (17/24 coded 8 or 17/37 coded 8), then her intent is unclear, so INTENT=3. If she and her husband disagree (17/24 or 17/37 coded 3), then they disagree, so INTENT=4. * (This test may also be written: 15/19 coded 1 or 16/84 coded 2 or 17/18 coded 1 or 17/20=1 or 17/21=1). VAR205 "Serv Used at 1st Family Plan Visit: New Method" (FP1MTHD VAR205 "Services used at the first family planning visit: got a new method" (FP1MTHD) If the respondent was 25 years of age or older at interview, or never had a family planning visit, or she never had intercourse (19/88-89 coded blank or 17/56 coded 2), or if the respondent received a pregnancy test only at first visit (20/44 coded 1), and reported no second visit for family planning services (20/45- 48 coded 9696), then services used at first visit is not applicable, code blank.

VAR940 "Poverty Level Income" (POVERTY) VAR940 "Poverty level income" (POVERTY) Poverty level income is the respondent's family income divided by the official poverty threshold for a family the size of her family, expressed as a percent. If the value is 998 or greater, set = 998. For this recode an exact family income is estimated by the midpoint of the reported range of family income (27/59-60) as follows: 01=2000, 02=3750, 03=5500, 04=6500, 05=7500, 06=8500, 07=9500, 08=10500, 09=11500, 10=12500, 11=14000, 12=16000, 13=18500, 14=22500, 15=30000, 16=42500, 17=55000. If the respondent is either person 01 or is related to Person 01 (02/56 coded 1, 2, 3, 4, 5, or 6), then her family size is the number of people living in the household (01/71-72), minus the number who are unrelated to Person 01 (i.e., the number coded 7 or 8 in 02/56). If the respondent is not related to Person 01 (02/56 coded 7 or 8), or if her relationship to person 01 was not ascertained (02/56 coded 9), then her family size is the count of the following persons: herself; her husband, if she is married (VAR915, MARITAL coded 1); and each of her children living in the household (07/45 coded 1). In addition, if the respondent is under age 25 (VAR905, AGE coded 15-24), add 1 for known adult relatives in her household (i.e., add 1 if 01/79 coded 2, 3, or 7; add 2 if 01/79 coded 1, 5, 6, 8).

For the problem cases, urban/rural codes were taken frsm the National Health Interview Survey (NHIS); this means that if the respondent moved between the NHIS and the NSFG, VAR956 refers to her former address rather than her current address. A variable, RURALFLG has been created showing the source of the urban/rural code: Polk or NHIS. This variable appears in tape location 2498. VAR970 "Years Since First Marriage" (MARR1/NOW) VAR970 "Years since first marriage" (MARR1/NOW) If the respondent has never been married (VAR916, FMARITAL coded 6), then MAR1/NOW does not apply, code blank. If the respondent has been marrried (VAR916, FMARITAL coded 1, 3, 4, or 5), then MAR1NOW is the century month of interview (03/25- 30) minus century month of first marriage (VAR976, FMAR1MO), divided by 12 and truncated to an integer. VAR976 "Century Month of First Formal Marriage" (FMAR1MO) VAR976 "Century month of first formal marriage" (FMAR1MO) If the respondent has never been married (VAR916, FMARITAL coded 6), then FMAR1MO does not apply, code blank. If the respondent has been married once (VAR518, FMARNO coded 1) and if that marriage is currently intact (VAR916, FMARITAL coded 1), then FMAR1MO is 22/78-83. If the respondent has been married once and that marriage is not intact (VAR518, FMARNO coded 1 and VAR916, FMARITAL coded 3, 4, or 5) or if she has been married more than once (VAR518, FMARNO coded 2-6), then FMAR1MO is 23/18-23.

If R has never been pregnant and has not had intercourse for the second time (11/18-21=9595), then if interview date (R-7) minus date of first intercourse (VAR540) LE 3, then she has had intercourse in the last 3 months, so SEXL3MO=1. if interview date (R-7) minus date of first intercourse (VAR540) GT 3, then she has not had intercourse in the last 3 months, so SEXL3MO=2. If R is currently pregnant (05/91=1), and R had periods of nonintercourse during the interval for the last pregnancy (10/19=1 AND 06/80=1), then the dates of nonintercourse are in 10/20-10/43. If R is not currently pregnant (05/91=2): if R has never been pregnant (05/92=2), and R has had periods of nonintercourse (11/18-21 NE 9595 or 9696), then dates of nonintercourse are in 11/19-41. if R has been pregnant (05/92=1), and R has had periods of nonintercourse since the last pregnancy (11/42=1), then dates of nonintercourse are in 11/43-66.

If the respondent became pregnant at about the right time (10/97 3), then the pregnancy occurred at the right time, so WANTWIFE=2. If the respondent wanted the pregnancy eventually, but became pregnant sooner than she wanted to become pregnant (10/97=1), then the pregnancy was mistimed, so WANTWIFE=3. If the respondent wanted the pregnancy and didn't care when it occurred (10/97=4), then the respondent was indifferent, so WANTWIFE=4. If the respondent did not want to have that pregnancy ever (10/95=2 or 10/96=2), then the pregnancy was unwanted, so WANTWIFE=5.

If R became pregnant sooner than her partner wanted her to become pregnant (10/99=1), then he thought the pregnant was mistimed, so WANTMANT=3. If her partner wanted the pregnancy and didn't care about its timing (10/99=4), then he was indifferent, so WANTMAN=4. If her partner did not want the pregnancy (10/98=2), then it was unwanted, so WANTMAN=5 If she didn't know or didn't remember whether her partner wanted the pregnancy (10/98=8), then its wantedness was undetermined, so WANTMAN=6. Missing data, code WANTMAN and impute. VAR994 "Pregnancy Outcome" (OUTCOME) VAR994 "Pregnancy outcome" (OUTCOME) This recode assigns a single outcome code to each pregnancy, even if the pregnancy had multiple outcomes.

If the pregnancy outcomes included an induced abortion but no live births (06/16-17 coded 02 or 06/19 coded 2),it is an induced abortion, so OUTCOME=2. If the pregnancy outcomes included a miscarriage but no live births or induced abortions (06/16-17 coded 03 or 10 or 06/19 coded 3), then the pregnancy was a miscarriage, so OUTCOME=3. If the pregnancy outcome included only stillbirths (06/16-17 coded 04 or 06/19 coded 4), then the pregnancy was a stillbirth, so OUTCOME=4. If the pregnancy is a current pregnancy, OUTCOME=5.

Variance estimation Appendix 6 - Variance Estimation Short-Cut Method for Numbers and Percents For users who wish to obtain variance estimates for total numbers or percentages of women or their pregnancies, there is an easier method than replicating estimates. Formulas are provided in this section that will provide suitable estimates for many applications. These estimates were derived by designing tables using a number of important dependent and independent variables. Sampling errors were calculated for the estimated numbers in these tables. The ratios of the variance to the square of the estimated number were plotted against the inverse of the estimated number, and a weighted least-squares line was fit to those points. The intercept and slope for these lines are given in this report; they can be used to estimate the standard errors of percentages and weighted numbers from the NSFC. To produce approximate standard errors for NSFC estimates, first determine the type of characteristic to be estimated, that is, the parameter set in table K to be used. The reader must then determine the type of estimate that is needed. The type of estimate corresponds to 3 rules. Rule 1. Estimated number of women or pregnancies - For the estimated number of women published in this report, there are two cases to consider. For the first case, if the estimated number is any combination of the poststratification cells in table G then its value has been adjusted to official U.S. Bureau of the Census figures and its standard error is assumed to be 0.0. This corresponds to parameter set V in table K. As an example, this would be the case for the number of women 15-44 the number of black women 15-44, or the number of never married or ever married women, the number of women 15-17, 18-19, 20-24, or in any other 5-year ago group. Although the race class "white" is not specifically adjusted to U.S Bureau of the Census figures, it dominates the poststratification "non-black" race class; consequently, subgroups of "white" women can be treated as the corresponding subgroup of non-black women in table C for the purpose of approximating standard errors. For the second case, the standard errors for all other estimates of numbers of women or pregnancies such as the number of women using the pill, are approximated by using the parameters provided in table K and formula 1 below. If the estimated number x for a characteristic has associated parameters a and b, then the approximate standard error for x, SE(x), can be computed by the formula 2 1/2 SE(x)= (ax + bx) (1) See also tables L1-L4, which evaluates this formula at many common levels. Example of rule 1. The estimated number of women using the pill is 10,734,000. From table K, parameter set III, the a and b parameters for the numbers of women are -0.00018 and 10,738. Using formula 1, the estimated standard error is 2 1/2 ( (-0. 00018)(10,734,000) + (10,738) (10,734,000)) = 307,000 An approximate 95-porcent confidence interval for the number of women using the pill is from 10,734 000 +- (1.96) times (307,449) Rule 2. For rates, proportions, and percents when the donomina- tor is generated by the poststratification classes (table G) - In this case, the denominator has no sampling error. For example, rule 2 would apply to the estimated percent of women using the pill in a combination of the poststratification cells. Approxi- mate standard errors for such estimates can be computed using the a and b parameters in table K along with formula 2 below. If the estimate of a rate, proportion, or percent p is the ratio of two estimated numbers p = x/Y (where p may be inflated by 100 for percents or 1,000 for rates per 1,000 women) , with y having no sampling error, then the approximate standard error for p is given by the formula 1/2 SE(p) = p (a + b/x) (2) See also table M1-M2, which evaluates this formula for many common values. Example of rule 2. The estimated proportion of all women 15-44 using the pill in 1988 was 15.6 percent. From table K, parameter set III, the parameters a and b for number of women are -0.00018 and 10,738, respectively. Using formula 2, the estimated standard error for the percent is 1/2 15.6 ((10.00018) + 10,738/10,734,000)) = 0.4 An approximate 95-percent confidence interval for the percent of women using the pill is 15.6 +- (1.96) (0.4), or 14.8 to 16.4 percent. Rule 3. Proportions and percents when the denominator is not generated by the poststratification classes - If p represents an estimated percent, b is the parameter from table K associated with the numerator characteristics, and y is the number of persons in the denominator upon which p is based, then the standard error of p may be approximated by 1/2 SE(p) = (bp(100-p)/y) (3) (If p is a proportion, then the above formula can be used but with 100 replaced by 1.0) - see table P1-P4, which evaluates this formula at many common levels. Example of rule 3. An estimated 30.7 percent of contraceptors were using the pill in 1988. This percent is based on the denominator estimated of 34,912,000 women using contraception. From table K, parameter set X, parameter b associated with health status is 3,640. Using formula (3), the standard error for the percent is 1/2 ((10,738)(30.7)(100-30.7)/34,912,000) = 0.8 percent An approximate 95 - percent confidence interval for the percent of contraceptors using the pill is 30.7 +- (1.96) (0.8), or 29.1 to 32.3 percent. Hypothesis Tests An estimate of the standard error of the difference, X-Y, between any two aggregates or percents is given by 2 2 1/2 5(X-Y) = (SX + SY ) 2 2 2 2 1/2 = ((X )RSE (X) + (Y )RSE (Y)) This expression provides a good estimate of the standard error for uncorrelated statistics, but it can be considered only a rough approximation otherwise. Because estimates from Cycle IV of the National Survey of Family Growth are based on a large sample of women and because the variance estimates were based upon such a large number of replicates (100), the test statistics X - Y t = ________ S(X-Y) will be approximately normally distributed. (See Wolter, 1985, Appendix B.) Therefore, individual two-tailed significance tests of differences between statistics from Cycle IV data can be performed with an approximate significance level of alpha by computing t and comparing it to the two-tailed 1-alpha critical value for the normal distribution. Example: In 1988, 33.92 percent of the pregnancies to black women ended before age 20, while for other women the corresponding percentage was 18.51. To test whether this racial difference significant at the 0.05 level of significance, compute 33.92 - 18.51 t = ------------------------------------------------------- 2 2 2 2 1/2 ((33.92) . RSE (33.92) + (18.51) . RSE (18.51)) Relative standard errors are computed using the appropriate values for B from Table K: RSE(18.51) = (13216)(100 - 18.51)/(18.51)(80,842,470) = 0.027 and 1/2 RSE(33.92) = ((4407)(100 - 33.92)/(33.92)(14,481,078)) = 0.024 thus 33.92 - 18.51 t = ------------------------------------------------- 2 2 2 2 1/2 ((33.92) (0.027) + (18.51) (0.044) ) = 12.5 The two-tailed .95 critical value (1 - alpha) for a normal statistic is 1.96. Therefore, the difference is significant at the .05 level. Tables Table K-Estimated Standard Error Parameters for Cycle IV Table K.
