Scope of Study

Summary:This series measures the prevalence and correlates of drug use in the United States. The surveys are designed to provide quarterly, as well as annual, estimates. Information is provided on the use of illicit drugs, alcohol, anabolic steroids, and tobacco among members of United States households aged 12 and older. Data are also provided on treatment for drug use and on illegal activities related to drug use. Questions include age at first use, as well as lifetime, annual, and past-month usage for the following drug classes: cannabis, inhalants, cocaine, hallucinogens, heroin, alcohol, tobacco, and nonmedical use of psychotherapeutics. Respondents were also asked about problems resulting from their use of drugs, alcohol, and tobacco, their perceptions of the risks involved, insurance coverage, and personal and family income sources and amounts. Demographic data include gender, race, ethnicity, educational level, job status, income level, household composition, and population density.

Geographic Coverage:United States
 
Time Period:1991
 
Unit of Observation:individual
 
Universe:The noninstitutionalized civilian population of the United States, aged 12 and older.
 
Data Type:survey data
 
Data Collection Notes:Data were collected by Research Triangle Institute, Research Triangle Park, NC, and prepared for release by National Opinion Research Center, Chicago, IL.
 
  For selected variables, statistical imputation was performed following logical imputation to replace missing responses. Unique code values (7, 8, or 9) were assigned to the recency-of-use variable when such logical imputation occurred. These code values are readily identifiable by the phrase "... LOGICALLY IMPUTED" in the code value descriptions. For those recency-of-use variables with missing data for which no indication of use of the drug could be found by examination of all relevant variables in the record, a code value of 91 ("Never Used") was assigned if there were one or more indications of such nonuse in the set of relevant variables.
 
  To protect the anonymity of respondents, all variables that could be used to identify individuals have been deleted from the public use file.
 

Methodology

Sample:Multistage area sample design with oversampling of six Metropolitan Statistical Areas of special interest: Washington, DC, New York City, Miami, Chicago, Denver, and Los Angeles. Minorities and youths aged 12-17 were also oversampled.
 
Weight:Data were weighted based on the three stages of sampling that were used. Adjustments were made to compensate for nonresponse and sampling error. Adjustments also included trimming sample weights to reduce excessive weight variation and a post-stratification to Census population estimates. The final weight variable to be used in analysis is ANALWT.
 
Data Source:personal interviews, including self-enumerated answer sheets for questions on drugs
 
Response Rates:Strategies for ensuring high rates of participation resulted in an interview response rate of 84.2 percent. Of the 32,594 completed interviews, 24,678 were with Whites and other (i.e., non-Hispanic, non-Blacks), 1,842 were with (non-Hispanic) Blacks, and 7,916 were with Hispanics. Approximately 7 percent (2,190) of the interviews were conducted using the Spanish version of the questionnaire. The completed interviews represented a 96.5 percent completion rate for screening sample households and an 84.2 percent for interviewing sample individuals. The response rates for these three racial/ethnic groups were 82.3 percent for Whites and others, 85.1 percent for Blacks, and 87.3 percent for Hispanics.
 
Extent of Processing:Performed consistency checks.
 
  Standardized missing values.
 
  Created online analysis version with question text.
 
  Checked for undocumented or out-of-range codes.
