This is the fourteenth annual survey in this series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. The students are randomly assigned one of five questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,300 variables across the questionnaires. Full details on the research design and procedures, sampling methodology, content areas, and questionnaire design, as well as percentage distributions by respondent's sex, race, region, college plans, and drug use, appear in the annual ISR volumes MONITORING THE FUTURE: QUESTIONNAIRE RESPONSES FROM THE NATION'S HIGH SCHOOL SENIORS.
These data are freely available.

Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: High school seniors in the contiguous United States.
Data Types: survey data
Data Collection Notes:
(1) Percentage distributions provided in the codebook were generated using full weights, which are not available on the public use files. Therefore, these results cannot be replicated using the public use files. The differences between results produced using the full weights and those produced using the sampling weights available on the public use files are estimated to be below 1 percent. (2) To protect the confidentiality of respondents, all variables that could be used to identify individuals have been collapsed or recoded on the public use files. These modifications should not affect analytic uses of the public use files. (3) The codebook is provided by ICPSR as a Portable Document Format (PDF) file. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR and SAMHDA Web sites.
Sample: Multistate area probability sample design involving three selection stages: (1) geographic areas or primary sampling units (PSUs), (2) schools (or linked groups of schools) within PSUs, and (3) students within sampled schools. Of the 69 PSUs, 16 were selected with certainty and 53 were selected with probability proportionate to size based on the size of the senior class. In schools with more than 400 seniors, a random sample of seniors or classes was drawn. In schools with less than 400 seniors, all seniors were asked to participate. Each school was asked to participate for two years, so that each year one-half of the sample is replaced. Schools refusing participation were replaced with similar schools in terms of geographic location, size, and type of school (e.g., public, private/Catholic, private/non-Catholic). The participation rate among schools has been between 66 and 80 percent since the inception of the study. The overall student response rate for 1988 was 83 percent.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Created online analysis version with question text.
Original ICPSR Release: 1990-05-09
- 2006-03-30 File CB9259.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.
- 2005-11-04 On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions.
- 2003-09-25 Value labels were added to the data definition statements.
- 2002-02-25 SAS and SPSS data definition statements are now available for this collection. Value labels are documented in the codebook. OSIRIS data dictionaries, card-image data files, and data map files are no longer distributed with this collection.
- 1997-12-19 The codebook is now available as a PDF file.
