title: Monitoring the Future: A Continuing Study of American Youth (12th-Grade Survey), 2001
title: Version 1

description: This is the 27th annual survey in this series that explores
 changes in important values, behaviors, and lifestyle orientations of
 contemporary American youth. Students are randomly assigned to
 complete one of six 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 1,400 variables across the
 questionnaires. Drugs covered by this survey include tobacco, alcohol,
 marijuana, hashish, LSD, hallucinogens, amphetamines (stimulants),
 Ritalin (methylphenidate), Quaaludes (methaqualone), barbiturates
 (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate),
 and heroin. Other items include attitudes toward religion, changing
 roles for women, educational aspirations, self-esteem, exposure to
 drug education, and violence and crime (both in and out of
school).
description: Each of the seven parts contains a weight variable, V5.
 They were originally varied by school but were modified to protect
 respondent confidentiality. Use the weight variable for all analyses,
 the results of which will differ slightly from published data tables
that used original data.
description: Response Rates: The overall student response rate for 2001 was 82
percent.
description: Multistage 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 72 PSUs, 8 were selected with
 certainty, 10 were selected with a probability of .50, and the
 remainder were selected probability proportionate to the size the
 senior class. In schools with more than 350 seniors, a random sample
 of seniors or classes was drawn. In schools with less than 350
 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 total
 sample was divided into six subsamples consisting of an average of
 2,300 respondents, and each subsample was administered a different
 form of the questionnaire, although all respondents answered the
 "core" drug and demographic questions. The participation rate among
 schools has been between 66 and 85 percent since the inception of the
study.

description: on-site questionnaire(1) To protect the privacy of respondents, all
 variables that could be used to identify individuals have been
 collapsed or recoded in the public use files. These modifications
 should not affect analytic uses of the public use files. (2) Variables
 omitted from the Western region questionnaires are noted in each
codebook.MTF does not release detailed geography codes in its public use files because of the disclosure risk it would cause. The MTF sample is drawn to generate representative samples of the four Census Bureau regions of the country (Northeast, Midwest, South, and West), but it does not generate representative samples of smaller geographic areas such as states, counties, or cities.
