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.

ICPSR removed variables VAR003_BG, VAR032, VAR363, VAR001_INTNO, and VAR147 from data and documentation to prevent disclosure risk.

The goal of the LAMAS studies is the development of a set of standard community profile measures appropriate for use in the planning and evaluation of public policy.

LAMAS 2 utilized a three-way controlled sampling of Los Angeles County with the following characteristics: 1. Census tracts were stratified according to median-income deciles, percent-white deciles, and geographic area. 2. A panel of 24 samples was designated and provided with probabilities, according to which a sample of 30 tracts was drawn. 3. These tracts were classified into three groups according to ethnic group, and blocks were sampled with a probability proportional to block size. 4. Housing units were selected systematically from each block after sample rates were calculated. For additional information regarding sampling, please refer to the Producer Documentation.

2017-03-07 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:

  • Checked for undocumented or out-of-range codes.

The data do not contain a weight variable.


  • Data in this collection are available only to users at ICPSR member institutions.
