Los Angeles Metropolitan Area Surveys [LAMAS] 2, 1970 (ICPSR 36612)
The Los Angeles Metropolitan Area Surveys [LAMAS] 2, 1970 collection reflects data gathered in 1970 as part of the Los Angeles Metropolitan Area Surveys (LAMAS). The LAMAS, beginning in the spring of 1970, are a shared-time omnibus survey of Los Angeles County community members, usually repeated twice annually. The LAMAS were conducted ten times between 1970 and 1976 in an effort to develop a set of standard community profile measures appropriate for use in the planning and evaluation of public policy.
The LAMAS instruments, indexes, and scales were used to track the development and course of social indicators (including social, psychological, health, and economic variables) and the impact of public policy on the community. Questions in this survey cover respondents' attitudes toward the following topics: air pollution, health care services in the community, local government politics, police relations, recreation, and leisure time. In addition, participating researchers were given the option of submitting questions to be asked in addition to the core items. These additional question topics include: sleep habits, the true self, impact of computers, job seeking behavior, and mental health and psychological factors.
Demographic variables included in this dataset include age, marital status, religion, sex, education, income, geographic origin, and race.

This survey of 12th-grade students is part of a 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, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), Quaaludes (methaqualone), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate), ecstasy, methamphetamine, and heroin. Other topics 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).
Highlights for 2021:
- Data collection resumed in 2021, with a change to all web-based surveys.
- Students completed the surveys on their personal or school-provided device.
- Non-survey variables have been changed or added to facilitate analyses. For details, please see the codebook section "MTF Variable Information - Non-survey variables included in the data files - Survey mode and design variables for 2021"
- Information about "screen break" issues, where series of questions were originally presented differently in the web-based survey as compared to the 2019/2020 tablet surveys. Please see the codebook and Appendix D for details.
- For 12th grade: two additional changes to the survey presentation. Please see the codebook section "MTF Variable Information - Non-survey variables included in the data files", and respective appendices for details.
