International sister studies

ELSA was established as a sister study to the Health and Retirement Study in the US. ELSA is now part of a growing network of longitudinal ageing studies around the world which provide national data on ageing as well as the opportunity for cross-national comparisons.

The Gateway to Global Aging Data provides tools and resources for sister study harmonisation. The platform offers a digital library of survey questions, a search facility for finding comparable questions across surveys, and identically-defined variables for cross-country analysis.
