Survey of Midlife in Japan (MIDJA 2), May-October 2012 (ICPSR 36427)
In 2008, with funding from the National Institute on Aging (NIA), baseline survey data for the Survey of Midlife in Japan (MIDJA), April-September 2008 were collected from a probability sample of Japanese adults (N=1,027) aged 30 to 79 from the Tokyo metropolitan area (ICPSR 30822). In 2009-2010 biomarker data was obtained from a subset of these cases (ICPSR 34969).
The survey and biomarker measures obtained parallel those in a national longitudinal sample of Americans known as Midlife in the United States or MIDUS (ICPSR 2760: MIDUS 1 and ICPSR 4652: MIDUS 2). The central objective was to compare the Japanese sample (MIDJA) with the United States sample (MIDUS) to test hypotheses about the role of psychosocial factors in the health (broadly defined) of mid- and later-life adults in Japan and the United States.
In 2012, with additional support from NIA, a longitudinal follow-up of the MIDJA sample was completed. The data collection for this second wave (N=657) largely repeated the baseline assessments. The goal of the follow-up wave was to conduct comparisons of longitudinal data available from the Japanese sample (MIDJA) and the United States sample (MIDUS) to test the hypothesis about the role of psychosocial factors in predicting health changes (including biomarkers) in both cultural contexts. Cultural influences on age differences in health and well-being were also of interest.
Demographic and background information included gender, age, education, marital status, household composition, and income.
Los Angeles Metropolitan Area Surveys [LAMAS] 3, 1971 (ICPSR 36611)
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.
