Panel Study of Income Dynamics (PSID)

The Panel Study of Income Dynamics (PSID) is the longest running longitudinal household survey in the world. The study began in 1968 with a nationally representative sample of over 18,000 individuals living in 5,000 families in the United States. Information on these individuals and their descendants has been collected continuously, including data covering employment, income, wealth, expenditures, health, marriage, childbearing, child development, philanthropy, education, and numerous other topics. The PSID is directed by faculty at the University of Michigan, and the data are available on this website without cost to researchers and analysts.

Project Talent

Project Talent is a national longitudinal study that first surveyed America’s high school students in 1960. At the time, it was the largest and most comprehensive study of high school students ever conducted in the United States. Over 440,000 students from 1,353 schools across the country participated in two full days or four half days of testing. The study was developed by the American Institutes for Research, a nonprofit, nonpartisan research institute, and several other organizations, including the University of Pittsburgh, through a Cooperative Agreement. It was funded by the United States Office of Education. Fifty years later, the American Institutes for Research is planning to follow up with participants from the original 1960 study.

Resources for Enhancing Alzheimer's Caregiver Health (REACH)

The REACH study was a multisite caregiver intervention study that compared a variety of interventions for dementia caregivers to control conditions. The study was a landmark in its large sample size, use of multiple sites, and inclusion of large numbers of White, Hispanic, and African American caregivers.

SHARE Israel

The Survey of Health, Ageing and Retirement in Europe (SHARE) is a multidisciplinary and cross-national panel database of micro data on health, socio-economic status and social and family networks of more than 55,000 individuals from 20 European countries aged 50 or over. Israel joined SHARE in 2004. The first wave of data collection was conducted in Israel between October 2005 and July 2006, among 1771 Israeli households. A total of 2598 men and women were interviewed face-to-face. The second wave of data collection started in August 2009 and ended in August 2010, making longitudinal data available.

Study on Global Ageing and Adult Health (SAGE)

The Study on Global Ageing and Adult Health (SAGE) is run by the World Health Organization's Multi-Country Studies unit in the Information, Evidence and Research Cluster. SAGE is part of the unit's Longitudinal Study Programme which is attempting to compile comprehensive longitudinal data on the health and well-being of adult populations, and the ageing process across different countries, through primary data collection and secondary data analysis.

Survey of Health, Ageing and Retirement in Europe (SHARE)

The Survey of Health, Ageing and Retirement in Europe (SHARE) is a multidisciplinary and cross-national panel database of micro data on health, socio-economic status and social and family networks of more than 85,000 individuals (approximately 150,000 interviews) from 19 European countries (+Israel) aged 50 or over. SHARE responds to a Communication by the European Commission calling to "examine the possibility of establishing, in co-operation with Member States, a European Longitudinal Ageing Survey.” SHARE is centrally coordinated by Axel Börsch-Supan, Ph.D. at the Munich Center for the Economics of Aging (MEA), Max Planck Institute for Social Law and Social Policy. It is harmonized with the U.S. Health and Retirement Study and the English Longitudinal Study of Ageing and has become a role model for several ageing surveys worldwide.

Swedish Adoption/Twin Study on Aging (SATSA)

The Swedish Adoption/Twin Study of Aging (SATSA) provides a unique opportunity to understand individual differences in aging. The twin design and the inclusion of twins reared apart makes it possible to study the importance of genetic and environmental factors that may underlie differing aging outcomes. Further, the broad spectrum of biological, psychological, and social domains assessed across the life span makes it possible to study patterns of change within and across domains and how these predict health and diseases of aging.

The China Health and Retirement Survey (CHARLS)

The China Health and Retirement Longitudinal Study (CHARLS) aims to collect a high quality nationally representative sample of Chinese residents ages 45 and older to serve the needs of scientific research on the elderly. The baseline national wave of CHARLS is being fielded in 2011and includes about 10,000 households and 17,500 individuals in 150 counties/districts and 450 villages/resident committees. The individuals will be followed up every two years. All data will be made public one year after the end of data collection.

The Irish LongituDinal Study on Ageing (TILDA)

The Irish LongituDinal Study on Ageing (TILDA) is a study of a representative cohort of over 8500 people resident in Ireland aged 50+, charting their health, social and economic circumstances over a 10-year period. The second wave of data collection was completed this year. TILDA is unique amongst longitudinal studies internationally in the breadth of physical, mental health and cognitive measures collected.

The Japanese Study of Aging and Retirement (JSTAR)

In order to establish a sustainable social security system in Japan, whose population is aging ahead of other developed countries, it is crucial to make available micro-data on the diverse aspects of the lives of elderly people. Extensive surveys have been conducted on elderly people in many other countries, and the resulting data have been utilized not only for academic and research purposes, but also as a valuable input for real-world policymaking. Despite the rapid aging of the Japanese population, no statistical survey that could properly capture the diversity of the elderly population from various viewpoints had been carried out in Japan until recently.

Against this backdrop, RIETI and Hitotsubashi University jointly launched a comprehensive survey of elderly people in 2007 to collect panel data on their lives and health, with the University of Tokyo joining from 2009 onward. The data collected in this survey include diverse information on the economic, social, and health conditions of elderly people. In addition, the survey is designed to ensure, to the maximum extent possible, comparability with preceding surveys such as the Health and Retirement Study in the United States, the Survey of Health, Aging and Retirement in Europe in continental Europe, and the English Longitudinal Study of Aging in the United Kingdom. Therefore, by analyzing JSTAR data, researchers can track the characteristics of the Japanese elderly population in terms of both their specificity and universality in the world. In this sense, JSTAR is Japan's first-ever globally comparable panel data survey of elderly people.
