  • Korean Longitudinal Study on Ageing "The purpose of KLoSA is to create the basic data needed to devise and implement effective social, economic policies to address the trends that emerge in the process of population ageing. The data will help identify and observe different dimensions of an aged society, build datasets that enable studies in different fields, and generate data comparable with similar panel studies in other countries (eg. U.S., Europe) that can provide the basis for policy-making and academic studies."
  • Japanese Study of Aging and Retirement (JSTAR): "This website provides information regarding the Japanese Study of Aging and Retirement (JSTAR), a panel survey of elderly people aged 50 or older conducted by the Research Institute of Economy, Trade and Industry (hereinafter "RIETI"), Hitotsubashi University, and, more recently, the University of Tokyo."
  • The Irish Longitudinal Study on Ageing (TILDA): A planned nationally representative survey that will act as the foundation for planning appropriate health, medical, social and economic policies. The proposed study will provide a comprehensive and accurate picture of the characteristics, needs and contributions of older persons in Ireland.
  • The China Health Aging and Retirement Longitudinal Study (CHARLS): "CHARLS is a biennial survey in China being conducted by the National School of Development (China Center for Economic Research) at Peking University. CHARLS aims to be representative of the residents of China age 45 and older, with no upper age limit."
  • Study on Global Ageing and Adult Health (SAGE) : "An ongoing program of work to compile comprehensive longitudinal information on the health and well-being of adult populations and the ageing process."

Studies in development:

  • Longitudinal Aging Study in India (LASI) : "LASI aims to supply the data needed to understand the situation of India's elderly population. This evidence base will contribute to cross-national studies of aging and will inform the design of policies that can protect and support the growing elderly community." (Pilot data available)
  • The Brazilian Longitudinal Study of Aging (ELSI-BRASIL)
  • Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA)
  • The Scottish Longitudinal Survey of Ageing (THSLS)
  • Health and Aging in Africa: Longitudinal Studies in Three INDEPTH Communities (HAALSI)
  • Canadian Longitudinal Study of Aging: "The Canadian Longitudinal Study on Aging (CLSA) is a large, national, long-term study that will follow approximately 50,000 men and women between the ages of 45 and 85 for at least 20 years. The study will collect information on the changing biological, medical, psychological, social, lifestyle and economic aspects of people's lives. These factors will be studied in order to understand how, individually and in combination, they have an impact in both maintaining health and in the development of disease and disability as people age."
