Los Angeles Metropolitan Area Surveys [LAMAS] 1, 1970 (ICPSR 36631)

Alternate Title:   LAMAS 1

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


The Los Angeles Metropolitan Area Surveys [LAMAS] 1, 1970 collection features 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 covered 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. Additional question topics included: politics in general, mobility, housing, schools, segregation, and social attitudes and opinions.

Demographic information collected includes age, race, sex, religion, marital status, education, income, and geographic origin.

  • 1970-05-15--1970-07-12

Unit of Observation:    Individual

Universe:    Households in Los Angeles County.

Data Type(s):    survey data


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.

Sample:    LAMAS 1-3 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 sampling, please refer to the Producer Documentation.

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

Weight:    The data are not weighted and there are no weight variables present in the dataset.

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 variable labels and/or value labels.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
