SHARE (Survey of Health, Ageing and Retirement in Europe) is a European research project that
examines ageing, in relation to health, health care, employment and retirement, socioeconomic and
financial status, social and family networks, and life and housing conditions.

At its core, SHARE is a European, longitudinal, multidisciplinary, and face-to-face survey of people
aged 50 or over, which has been conducted every two years since 2004 in a number of European
countries (28 countries represented in the most recent wave).

During the first 8 waves, 140,000 people (9,000 in France) took part in the survey at least once, which
corresponds to a total of 480,000 individual interviews (30,000 in France) being conducted.
Information collected via the regular SHARE panel study has also been complemented with
interviews that are either an addition to or a replacement of the regular SHARE interview: SHARELIFE
(special interviews covering the retrospective life histories and childhood living conditions of the
respondents), SHARE Corona (a survey on the impact of the Covid-19 pandemic), and SHARE-HCAP (a
survey on the maintenance of cognitive function of the 65 and up population).
The data produced by SHARE are made available to the scientific community as "open data.” To date,
the data have been disseminated to roughly 15,000 users and more than 3,400 publications
exploiting the SHARE data have been produced.
SHARE is also comparable with other similar surveys conducted in countries such as the United
States, England, Ireland, Japan, China, Brazil, India, Mexico, and South Korea. As a result, these
harmonised data can be leveraged to conduct large-scale international analyses on the effects of

The LEDa - LEGO team of the University of Paris Dauphine - PSL has been responsible for the scientific
and operational management of the SHARE project in France (SHARE-France) since 2012. SHARE-
France is funded by the French Ministry of Higher Education and Research, TGIR Progedo, CNSA
