The region was defined in 1987 in the Territorial Planning Laws approved by the Parliament of Catalonia. It currently comprises the comarques of Baix Llobregat, Barcelonès, Maresme, Vallès Occidental and Vallès Oriental, that is, Barcelona and its area of economic and market influence. Alt Penedès and Garraf were initially part of it as well, but were integrated into the new area of Penedès in 2017. In April 2008, the Department of Territorial Policy and Public Works of the Generalitat de Catalunya presented the preliminary draft of the Barcelona Metropolitan Territorial Plan, which delimits the areas of scenic and strategic interest that are to be preserved and aims to promote a quality road and rail network. Demography
