Municipal level government by population size

This dataset includes data on average and median municipal population size, and the share of municipalities by size classes, distinguishing between the following categories: less than 2 000 inhabitants, between 2 000 and 4 999 inhabitants, between 5 000 and 19 999 inhabitants, and more than 20 000 inhabitants.

The Subnational Government Structure and Finance Dashboard compiles several datasets with comparable data on institutional organisation and public finance at subnational government level. It provides data for the year 2025 (or latest year available), for all 38 OECD member countries, and the average for the European Union. It includes data for the subnational government sector (for both state and local government levels).

The data is also available in PDF format and via an Interactive dashboard.
