Midlife in the United States
Midlife in the United States (MIDUS) is a national longitudinal study of health and well-being. It was
conceived by a multidisciplinary team of scholars interested in understanding aging as an integrated bio-psycho-social process. Since its inception
in 1995 MIDUS has continued to grow, such that it now includes data from over 10,000 individuals, comprising thousands of variables in different
scientific areas among distinct cohorts.
This website is a one-stop repository that provides MIDUS data and metadata (information about data) for exploration and analysis. Users can read
project abstracts, search for variables within or across datasets, download instruments, documentation, and codebooks, and download datasets from
the official MIDUS archive.
The MIDUS study and this repository are supported by multiple grants from the National Institute on Aging (5R37AG027343, 5P01AG020166,
1R03AG046312) and by the University of Wisconsin Institute on Aging. This repository is based on the
Data Documentation Initiative (DDI) metadata standard and is powered by
Colectica software. Please feel free to explore the repository and send any feedback or

||In 2011 MIDUS began data collection on a new national sample of American adults to "refresh" the original MIDUS cohort and to examine the health impacts of the economic recession.
||The MIDJA study is a probability sample of Japanese adults (N = 1,027) aged 30 to 79 from the Tokyo metropolitan area that includes many of the measures from the MIDUS Survey and Biomarker projects.
||The MIDJA Biomarker study includes biomarker assessments, drawn from the MIDUS Biomarker study, for a sub-sample of the MIDJA respondents.
