This project extended SHARE to the eight EU member states which have not been covered by SHARE until Wave 6: Finland, Latvia, Lithuania, Slovakia, Romania, Bulgaria, Malta and Cyprus and integrate these countries into SHARE Wave 7. The project also covered the development and testing of the SHARE core questionnaire for Wave 8 and the implementation of the main data collection of Wave 8 in these countries. Moreover, the project supported the four crisis countries Portugal, Spain, Greece and Estonia as well as the final database construction, data checks, and data provision after the completion of the main data collection of Wave 8. The project thus enables the EU Commission and researchers to perform comparative analyses on topics such as employment, health, economic and social status with strictly harmonized data across all EU Member States.
