Record Linkage Project

The combination of survey data with administrative records (named “record linkage” in the following) is a promising innovation within social surveys. SHARE aims at integrating country specific record linkage projects to expand the survey data and its research potential.

The first country which implemented record linkage was Germany, where the so-called SHARE-RV project was established. Starting with a pilot of SHARE-RV in the third wave of SHARE, the project was continued in Germanys’ Waves 4, 5 and 6 (see SHARE-RV).

After the success of the German record linkage project this approach was scaled up to other SHARE countries.

REGLINK-SHAREDK is the second successful linkage project in SHARE and relates to the Danish subsample of SHARE. The linkage in Denmark was completed in February 2017 by establishing the project as a national research infrastructure (see REGLINK-SHAREDK).

Information on other national implementation of the record linkage projects will follow as soon as these are fully established.
