Los Angeles Metropolitan Area Surveys [LAMAS] 3, 1971 (ICPSR 36611)

Alternate Title:   LAMAS 3

Principal Investigator(s): University of California, Los Angeles. Institute for Social Science Research


The Los Angeles Metropolitan Area Surveys [LAMAS] 3, 1971 collection reflects data gathered in 1973 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: the concept of a model neighborhood, air pollution, medical problems and health care services in the community, local government politics, police relations, crime, the Mexican-American protests, and public transportation. A sub-sample of households in the San Fernando Area were asked questions about the 1970 earthquake, rating the effectiveness of local government response and the respondents' feelings about possible future disasters.

Demographic variables included in this dataset include age, marital status, religion, sex, education, income, geographic origin, and race.

Data Collection Notes:

ICPSR removed the variable V518 (coder ID) from data and documentation to prevent disclosure risk.


Study Purpose:    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.


Sampling information was not provided with the deposit and has been extrapolated from the documentation that accompanied LAMAS 1 and LAMAS 4.

LAMAS 3 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 sample, please refer to the accompanying documentation.

Time Method:    Cross-sectional , Longitudinal: Trend / Repeated Cross-section

Weight:    The data do not contain a weight variable.

Mode of Data Collection:    face-to-face interview

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