6There is a tendency to consider groups of municipalities as metropolitan areas, although they do not present enough population nor urban structure. For the Algarve, a region with less than 500 000 resident inhabitants, the “GAMAL” –Great Metropolitan Area of Algarve– was officially created in 2004: the statutes have been published the 29 April on “Diário da República no 101– III Série”. In 2008, this denomination changed to “Comunidade Intermunicipal do Algarve” and the statues published the 19 December.
