U.S.
Census Populations With Bridged Race Categories
The National Center for
Health Statistics releases bridged-race population estimates of the resident
population of the United States, based on Census 2000 counts, for use in
calculating vital rates. These estimates result from bridging the 31 race
categories used in Census 2000, as specified in the 1997
Office of Management and Budget (OMB) standards for
the collection of data on race and ethnicity, to the four race categories
specified under the 1977 standards. Many data systems, such as vital
statistics, are continuing to use the 1977 OMB standards during the
transition to full implementation of the 1997 OMB standards. The
bridged-race population estimates are produced under a collaborative
arrangement with the U. S. Census Bureau. The bridging methodology is
described in the report, “Census 2000 Populations with Bridged Race
Categories” which was published in September 2003 and is available for
download from this site.
The bridged single-race
population estimates are being used to calculate birth and death rates
produced by NCHS for data year 2000 and later years, as well as to produce
revised birth and death rates for the 1990s. Published reports that used
the 1990-based postcensal population estimates have been re-issued in whole
or in part.
Comments Although efforts
were made to use the best available data and methods to produce the bridged
estimates, the modeling process introduces error into the estimates. The
potential for error will be greatest for the smallest population groups,
particularly the smaller race groups and county level estimates. NCHS would
appreciate receiving feedback on the usefulness of the estimates as well as
any problems that have been identified. Please provide comments via e-mail
to: POPEst@cdc.gov.
