Politically, Northern Portugal is divided into 86 municipalities (
municípios), which in turn are subdivided into 1,426 civil parishes (
freguesias). The region was subdivided in supramunicipal districts in 1835. Northern Portugal includes the districts of Viana do Castelo, Braga, Porto, Vila Real, and Bragança, and partly the districts of Aveiro, Viseu, and Guarda. The largest municipalities are
Vila Nova de Gaia (304,149),
Porto (231,962),
Braga (193,333),
Matosinhos (172,669),
Gondomar (164,255),
Guimarães (156,852),
Santa Maria da Feira (136,720),
Maia (134,959),
Vila Nova de Famalicão (133.590) and
Barcelos (116,777), according to the
2021 Census. Ignoring municipal subdivisions, the region has one urban area, Greater Porto, with about one million inhabitants, this includes Porto, Vila Nova de Gaia, Matosinhos, Maia and some large suburbs such as Rio Tinto and Ermesinde. There is a significant urban network just above Greater Porto, with about 600,000 inhabitants: the Minho Urban Quadrilateral (
Quadrilátero Urbano do Minho), which includes Braga, Guimarães, Vila Nova de Famalicão and Barcelos; and the urban area of Póvoa de Varzim-
Vila do Conde, with about 100,000 inhabitants. However, in Northern Portugal these tend to be well-populated with
dispersed settlement between the diverse cities of the region. All these human settlements are part of the same polycentric urban-metropolitan agglomeration with 2,99 million inhabitants (2001), alongside the northern Atlantic coast. The EOCD using the Functional urban areas methology, using 2014 statistics, recognizes one metropolitan area: Porto (1,313,829inh.), one medium sized-urban area Braga (256,427) and three small urban areas: Guimarães (182,433), Viana do Castelo (88,848), and Póvoa de Varzim (63,428). According to the Portuguese statistics institute, the INE, in the 2011 Census: 4.7% of the population was foreign-born, most arrived from France, Angola, Brazil, Mozambique, Venezuela, Germany, Switzerland, Spain, South Africa, China, and Romania. ==Economy==
