Analysing the evolution of construction based on the number of residents in Lisbon, it has been concluded that, between 2016 and 2021, around 9.7 properties were built for every 10,000 residents in Lisbon. Two decades earlier, this ratio amounted to 32 properties per 10,000 inhabitants.

These are some of the conclusions contained in the data on the platform launched by INE, through which it is possible to check the construction period of each building indicated in the last 2021 Census, in each street of five cities (Lisbon, Porto, Coimbra , Évora and Faro) where the national statistics office has delegations. On the islands, the platform also provides data on Funchal, Angra do Heroísmo, Ponta Delgada and Horta.

The data also show that around one hundred years ago, until 1919, 8,322 buildings were built in the municipality of Lisbon. At that time, there were 191 properties for every 10,000 residents in Lisbon, when the population of the capital amounted to 435,359 people, according to the “Statistics of the Physiological Movement of the Population of Portugal”.

In Porto, between 2016 and 2021, more properties were built than in Lisbon. During this period, in the municipality of Porto, 768 residential and non-residential properties were completed. 470 less than those built at the beginning of the millennium, when between 2001 and 2005 1,238 properties were completed.

Among the five mainland cities analysed by INE, it was in Faro that there was the least construction of properties between 2016 and 2021, with only 91 buildings being built in that period. In total, the municipality of the Algarve capital has 5,572 residential and non-residential buildings.
