About half of the population residing in Portugal is concentrated in just 31 municipalities, mainly located in the metropolitan areas of Lisbon and Porto.
The imbalances in the distribution of the population on the territory “are accentuated”, notes the National Institute of Statistics (INE), noting that “the demographic evolution of the last decade at the level of the municipality makes it possible to verify that the territories located in the interior of the country have lost population and that the municipalities which record population growth are located mainly on the coast â.
In addition, according to the data, there is “a concentration” around Lisbon and in the Algarve region.
At the municipal level, âthe most significant population increases of the last decadeâ were recorded in Odemira (13.5%) and Mafra (12.8%), followed by Palmela, Alcochete, Vila do Bispo and Montijo, with values ââbetween 9.6% and 8.7%.
At the opposite extreme, Barrancos, TabuaÃ§o, Torre do Moncorvo and Nisa observed “the most expressive population declines, with values ââabove 20%”, according to the data.
The 10 most populous municipalities are Lisbon, Sintra, Vila Nova de Gaia, Porto, Cascais, Loures, Braga, Almada, Matosinhos and Oeiras, but the two largest cities recorded population losses: Porto with less than 2.4 % and Lisbon with less than 1.2%. Matosinhos and Oeiras follow the trend of population reduction.
The municipality of Braga recorded the âmost expressiveâ growth (6.5%), followed by Cascais and Sintra, with 3.7% and 2.1% respectively.
