The Los Angeles Metropolitan Area Surveys [LAMAS] 10, 1976 collection reflects data gathered in 1976 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: child abuse, parent-child relationships, right to privacy, and political participation. 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: accidents and emergencies, crime, and health care/relationship to doctors.

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

ICPSR did not prepare the Vignette data for dissemination due to disclosure risk concerns as well as incomplete information.

ICPSR removed variables TACT (census tract), BG_ED (Block group), BLK (block number), LB (logical block), CLUST (cluster), TIME_BEG, and TIME_END (time interview began and completed) from the data to prevent disclosure risk. Additionally, ICPSR removed value labels from the variable CODER in order to anonymize interviewer names.

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 utilizes a multistage, stratified probability sample with the following characteristics: 1. Los Angeles County is divided into ten geographic regions. 2. Block groups in each region are stratified by housing value, percentage owner-occupied, and percentage nonwhite. 3. 100 block groups are sampled from the ten regions. 4. Two block clusters are drawn from each of the 100 block groups. Household respondents were selected according to the KISH-TABLE method. The LAMAS used the unclustered nature of the sample to over sample selected sub-populations such as ethnicity. Additional information is available in the study documentation.


Longitudinal: Trend / Repeated Cross-section

Households in Los Angeles County


survey data

This collection includes two datasets, both include identical variables, all related to child abuse and what parent-child relationships could contribute to child abuse. The two datasets are for the county representative sample of the LA Metropolitan area households and the Hispanic oversample and have 1,039 and 1,065 cases, respectively, with the second dataset including the Hispanic oversample. The representative sample of the county can be compared to the Hispanic oversample. For additional information, please refer to the Producer Documentation.



2017-09-05 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.

There are no weights present in the dataset.


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