As a counterpart to my metropolitan geography database for the U.S., which receives dozens of hits a day, I have added a directly analogous database for European geographies, which may be useful for economic analysts or other wanting a quick overview. This tool presents several tables that organize European geographic taxonomies in a way that is not easily available on EU or national statistical agency websites.
As with the U.S. database, this one holds almost no demographic data. It exists simply to exhibit the relationship among the various geographies and taxonomies. The tables are populated with 2013 Eurostat definitions of NUTS (Nomenclature of Units for Territorial Statistics). Instructions/troubleshooting/caveats are here. Comments/corrections are welcome.
