National Epidemiologic Survey on Alcohol and Related Conditions (NESARC)
Welcome to the NESARC website. The NESARC was conducted and sponsored by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The NESARC is the primary source for information and data on the U.S. population for:
- alcohol and drug use;
- alcohol and drug abuse and dependence; and
- associated psychiatric and other medical comorbidities.
NESARC was designed to be a longitudinal survey with its first Wave of interviews fielded in 2001-2002. The second Wave of interviews is planned for 2004-2005. The NESARC is a representative sample of the United States population and 43,093 Americans participated in the first Wave of the survey. During Wave 2, an attempt to re-interview all 43,093 of these respondents will be made. The target population of the NESARC is the non-institutionalized household population, 18 years and older, residing in the United States including the District of Columbia, Alaska, and Hawaii. Additionally the following non-institutional group quarters housing units were included as part of the NESARC sample: boarding houses, rooming houses, non-transient hotels and motels, shelters, facilities for housing workers, college quarters, and group homes. The sample provides estimates for the nation as a whole on topics related to alcohol and drug use, abuse and dependence and their associated disabilities.
In 1991-1992, NIAAA conducted the National Longitudinal Alcohol Epidemiologic Survey (NLAES), that despite its name, was a cross-sectional survey of the U.S. population. The NLAES public use data file and associated documentation may be obtained by contacting CSR, Incorporated, the contractor that maintains this website (see contact information).
The NLAES and NESARC should be cited as follows: NIAAA 1991 - 1992 NLAES and the NIAAA 2001 - 2002 NESARC.
