The Subnational Government Structure and Finance Dashboard displays comparable graphs on the institutional organisation and public finance at subnational government level for 38 OECD member countries. The graphs show the averages – weighted – for unitary and federal countries as well as the average for the European Union and the OECD for the latest year available. This data comes from a database accessible via the Data Explorer: OECD data on subnational government finance and employment.
The data is also available in PDF format.
