France's national statistics office, INSEE, names an urban core and its surrounding area of commuter influence an (or AAV, literally meaning "catchment area of a city"), plural: aires d'attraction des villes. The official translation of this statistical area in English (as used by INSEE) is "functional area". The AAV follows the same definition as the Functional Urban Area (FUA) used by Eurostat and the OECD, and the AAVs are thus strictly comparable to the FUAs.
