According to the 2025 resident population estimates, which include revisions to the figures for the period between 2021 and 2024, on 31 December 2025, the population in Portugal is 11,424,031, exceeding the figure presented last year for 2024 (10,749,635), which was also updated to 11,387,222.

In 2024, instead of 1.6 million foreign residents, IBGE had counted only 177,557 people.

According to a note released by the INE (National Institute of Statistics), the resident population in Portugal in 2025 was estimated at 11,424,031 people, representing an increase of 36,809 people (0.32%) compared to 2024.

According to the INE, the previously released data has been updated, concluding that, “between 2021 and 2025, the resident population increased by 824,914 people, with the years 2022, 2023 and 2024 standing out, in which exceptionally high migratory flows were observed, resulting in population increases”, respectively, of 330,000, 275,000 and 183,000 people.

Demographic ageing

On the other hand, “demographic ageing in Portugal continued to intensify, although mitigated by the relative increase in the working-age population,” and in 2025, the ageing index reached almost double the number of elderly people compared to young people, “19 elderly people for every 10 young people,” when in 2021 the figures were 18 per 10.

The median age of the resident population in Portugal rose to 45.8 years, compared to 46.1 in 2021, the date of the last census, indicating a slight rejuvenation.

“The resident population of foreign nationality, as of 31 December 2025, was estimated at 1,597,539 people, representing 14.0% of the total resident population,” and since 2021, “it has more than doubled, corresponding to an increase of 849,384 people (an increase of 6.9 percentage points),” says the INE (National Institute of Statistics).

The latest data from the Integration, Migration and Asylum Agency (AIMA), from October of last year, indicated that, at the end of December 2024, there were 1,543,697 registered foreign citizens residing in the national territory, lower than estimates made in April.
