Functional area (France)

An aire d'attraction d'une ville (or AAV, literally meaning "catchment area of a city") is a statistical area used by France's national statistics office INSEE since 2020, officially translated as functional area in English by INSEE, which consists of a densely populated urban agglomeration and the surrounding exurbs, towns and intervening rural areas that are socioeconomically tied to the central urban agglomeration, as measured by commuting patterns. INSEE's functional area (AAV) is therefore akin to what is most often called metropolitan area in English.
