Key Performance Indicators
This subpage provides an overview of the most important Key Performance Indicators (KPIs). It summarizes key metrics that offer insight into the scope, reach, and use of our activities.
Our KPIs offer a clear picture of our consistent progress and performance. They highlight how we consistently work towards our goals. Each year, we achieve important milestones across the KPIs listed below. We are proud of the collaboration within SHARE Central, the country teams, and the entire network. Most importantly, we are grateful to the respondents who make this work possible.
Comment on the Interpretation of the Numbers
Please note that these numbers are presented for the purpose of obtaining a quick overview of SHARE’s operations – they cannot and should not, however, be used to compare SHARE against other Research Infrastructures (RIs) since KPIs with the same names often have fundamentally different meanings for different RIs.
The number of users, for instance, heavily depends on the type of RI and the modes of access. Commercial partners are, for example, necessarily excluded by the nature of SHARE as a social survey based on voluntary participants who report very private health and economic data. Commercial use is thus out of the question due to SHARE’s strict protection of the data of its respondents, which in turn affects the number of users.

Number of Participants in the Survey
Since 2004, SHARE has been collecting socio-economic and biomedical data from about 160,000 people aged 50 and older in 28 countries in Europe and beyond.
Number of Interviews conducted
As of Wave 9, the latest wave of data collection, SHARE has conducted around 616,000 in-depth interviews with 160,000 respondents. In general, specially trained interviewers collect the data on the participants’ economic, social and health situation in computer-assisted personal interviews.
Number of Publications
Number of Data Users worldwide
In 2024, SHARE passed the mark of 20,000 registered SHARE users, with a total of 23,360 user registrations by the end of 2025.
These numbers emphasise the importance of SHARE and its data for studying the effects of health, social, economic, and environmental policies over the life course of individuals.
Size of the Net Samples
Number of Countries involved in Linkage
SHARE encourages record linkage projects in its member countries to enhance survey data with objective administrative data.
Combining survey data as a more subjective perspective on respondents’ lives and administrative data optimally exploits the advantages of both data sources.
Linked data are currently available in four countries (Germany, Denmark, the Netherlands, and Finland) with more countries expected to follow.
