Sampling

Sample Design

Cross-sectional, multistage area probability sampling to obtain a nationally representative sample. Oversampling of women, teens (ages 15 to 19 years), Blacks, and Hispanics.

Approximately 22,600 individuals (approximately 10,000 men and 12,000 women), ages 15 to 44 years, are represented in the 2006-2010 data file. The 2006-2010 survey cycle sample was drawn from 110 areas (defined by primary sampling units [PSUs]). In each survey year in the 2006-2010 cycle, approximately 5,500 individuals were interviewed. Sample sizes of the six surveys conducted between 1973 and 2002 range from approximately 8,000 to approximately 11,000 interviews.

Restricted data are available through the National Center for Health Statistics Research Data Center. The initial set-up fee for obtaining data through the Research Data Center is $750. Access fees vary depending on mode of access. Learn more.

Special Note(s)

Access to certain data is restricted, including details about race/ethnicity and characteristics of the respondent’s household. A complete list of restricted-use variables for the female survey is available. A list of restricted-use variables for the male survey also is available.

Contextual data files for the 2006-2010 survey, which include information on the context or community in which respondents live, are available through the National Center for Health Statistics Research Data Center. Contextual data files are available for the 1995 and 2002 public use data files as well. Learn more about accessing data through the Research Data Center. The two contextual data files are based on the respondent’s address at the time of the interview and on April 1, 2000 (the time of the 2000 US Census). Geographic variables are provided at the state and county levels in these data files.

The most recent year for which data are available is not necessarily the most recent year this survey was conducted.
