Functional area

Functional areas (AAV) of Metropolitan France in 2020, broken down by communes (commune borders as of January 1, 2020):
  Communes in the main population and employment centre of a functional area
  Communes in a secondary population and employment centre of a functional area
  Communes in the commuting zone of a functional area (functional areas with more than 700,000 inhabitants)
  Communes in the commuting zone of a functional area (functional areas between 200,000 and 700,000 inhabitants)
  Communes in the commuting zone of a functional area (functional areas between 50,000 and 200,000 inhabitants)
  Communes in the commuting zone of a functional area (functional areas with less than 50,000 inhabitants)

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.
