The Health and Retirement Study (HRS) [1] is a longitudinal survey of a representative sample of Americans over age 50 conducted by the Survey Research Center (SRC) at the Institute for Social Research (ISR) at the University of Michigan in Ann Arbor and supported by the National Institute on Aging (NIA). The study interviews approximately 20,000 respondents every two years on subjects like health care, housing, assets, [2] pensions, [3] employment and disability. The study is managed through a cooperative agreement (NIA U01AG009740) between the NIA, which provides primary funding, and the ISR, which administers and conducts the survey. Beginning in 2012, HRS began adding genetic information from consenting participants to its database. [4] The economic measures captured by the data in the HRS are regarded as being of very high quality. [5]
The HRS is designed to inform the national retirement discussion as the population ages. The inspiration for the HRS emerged in the mid-1980s, when scientists at NIA and elsewhere recognized the need for a new national survey of America’s expanding older population. By that time, it had become clear that the mainstay of retirement research, the Retirement History Study (RHS), conducted from 1969 to 1979, was no longer adequately addressing contemporary retirement issues. For example, the RHS sample underrepresented women, Blacks, and Hispanics who, by the mid-1980s were a growing part of the labor force. The RHS also did not ask about health or physical or mental function, all of which can affect the decision and ability to retire. Moreover, research on the retirement process was fragmented, with economists, sociologists, psychologists, epidemiologists, demographers, and biomedical researchers proposing and conducting studies within their own "silos," often without regard to the relevant research activities of other disciplines. [6]
Determining that a new approach was needed, an Ad Hoc Advisory Panel was convened by the National Institute on Aging. In early 1988 the panel recommended the initiation of a new, long-term study to examine the ways in which older adults’ changing health interacts with social, economic, and psychological factors and retirement decisions. Government experts and academic researchers from diverse disciplines were recruited to collaboratively create and design the study. Ultimately, relevant executive agencies and the United States Congress recognized the value of this major social science investment, and the HRS was established.
Many individuals and institutions have contributed to the planning, design, development, and ongoing administration of the study. This includes the study’s leadership at the Institute for Social Research, specifically the first HRS Director, F. Thomas Juster, who led the effort to initiate the HRS, [7] Robert J. Willis, the Director from 1995 to 2007, and David R. Weir, the current Director. HRS relies on the contributions of the HRS co-investigators, a multidisciplinary group of leading academic researchers at the University of Michigan and other institutions nationwide, a steering committee and working groups, which have provided critical advice about the study’s design and monitored its progress, and the NIA-HRS Data Monitoring Committee, an advisory group of independent members of the academic research community and representatives of agencies interested in the study.
In addition, the Social Security Administration has provided technical advice and substantial support for the study. Over the HRS’s history, other important contributors have included the United States Department of Labor’s Pension and Welfare Benefits Administration, the United States Department of Health and Human Services Office of the Assistant Secretary for Planning and Evaluation, and the State of Florida.
The HRS has a number of sister studies in other countries. In recent years, the HRS has been extended to several Asian countries, including Korea (the Korean Longitudinal Study of Aging or KLoSA), Japan (the Japanese Study of Aging and Retirement or JSTAR), China (the Chinese Health and Retirement Survey or CHARLS), India (The Longitudinal Aging Study in India or LASI) and New Zealand (Health, Work and Retirement Study). Population aging is very rapid in Asia and India and China alone will have more than one billion people over age 60 during this century. CHARLS is headed by a team at the Chinese Center for Economic Research (CCER) at Peking University under the direction of Professor Zhao Yaohui. LASI is jointly headed by a team from Harvard University under the direction of Professor David Bloom and the International Institute of Population Studies (IIPS) in Mumbai India. Both CHARLS and LASI were awarded peer review grants to conduct pilot studies by the National Institute of Aging in the United States. Other studies include:
The Gateway to Global Aging Data, a resource that facilitates the use and harmonization of the different datasets of HRS and sister studies in other countries has been developed with support of the National Institute on Aging, National Institutes of Health (RC2 AG036619-01 and R01 AG030153)
Retirement is the withdrawal from one's position or occupation or from one's active working life. A person may also semi-retire by reducing work hours or workload.
The National Longitudinal Surveys (NLS) are a set of surveys sponsored by the Bureau of Labor Statistics (BLS) of the U.S. Department of Labor. These surveys have gathered information at multiple points in time on the labor market experiences and other significant life events of several groups of men and women. Each of the NLS samples consists of several thousand individuals, many of whom have been surveyed over several decades.

China Family Panel Studies is a nationally representative, biennial longitudinal general social survey project designed to document changes in Chinese society, economy, population, education, and health. The CFPS was launched in 2010 by the Institute of Social Science Survey (ISSS) of Peking University, China. The data were collected at the individual, family, and community levels and are targeted for use in academic research and public policy analysis. CFPS focuses on the economic and non-economic well-being of the Chinese people, and covers topics such as economic activities, educational attainment, family relationships and dynamics, migration, and physical and mental health. The themes cover social, economic, education, health and so forth.

James Nazroo, PhD, MBBS FBA FaCSS, is Professor of Sociology at the University of Manchester. He is the founding and Deputy Director of the ESRC Centre of Dynamics of Ethnicity (CoDE), co-Principal Investigator (PI) of the Synergi Collaborative Centre, which is investigating ethnic inequalities in severe mental illness, and founding and co-Director of the Manchester Institute for Collaborative Research on Ageing (MICRA). Issues of inequality, social justice and underlying processes of stratification have been the primary focus of his research activities, centring on ethnicity/race, ageing, gender, and the interrelationships between these. Central to his work on ethnicity/race has been developing an understanding of the links between ethnicity, racism, class and inequality. This work has covered a variety of elements of social disadvantage, how these relate to racialised identities and processes of racism, and how these patterns have changed over time. He has also explored the role of access to and quality of health services, including a critical examination of mental health services. His research on ageing has been concerned to understand the patterns and determinants of social and health inequalities in ageing populations. He has conducted studies on quality of life for older people among different ethnic groups in the UK, on inequalities in health at older ages, and on routes into retirement and the impact of retirement on health and well-being. He was PI of the fRaill programme, an interdisciplinary study of inequalities in later life, and is co-PI of the English Longitudinal Study of Aging (ELSA) which is a multi-disciplinary panel study of those aged 50 and older.
