ESS Multilevel Data 2025, NUTS1, edition 1.1

There are numerous sources containing contextual data. The ESS MD does not contain everything available. The selection of variables is based on the recommendations in the report of the ESS Upgrade and Planning Group on Contextual Data: 'Conceptual and Statistical Issues in Multilevel Analysis’.

In addition there are five files including multilevel data on country level, NUTS1, NUTS2 and NUTS3 level as well as on the NUTS level used for each country in ESS11 (ESS11MD_reg11).

The survey involves strict random probability sampling, high response rate and rigorous translation protocols.
