This partnership is known as the European Statistical System (ESS). It also includes the statistical offices of the European Economic Area (EEA) countries and Switzerland.

Eurostat also coordinates the statistical activities of the European Commission.
Eurostat is part of the initiative on Statistical Data and Metadata eXchange (SDMX).

Through TED, business opportunities are offered free of charge in the European Union, the European Economic Area and beyond. The database only includes the last 5 years of the Supplement.
