Extended results on foreign population

The Population and Housing Census provides information on the foreign population living in Catalonia according to their nationality. The available series of extended results starts in 2021 and is updated annually.

The Population Census is produced annually, starting in 2021, by combining administrative records, of which the Population Register is the main one. When preparing the Population Census, the statistical treatments and procedures applied, including comparisons with other sources, make it possible to offer a more accurate statistical count of the population and its characteristics than the Population Register. From 2021, the Population Census is considered the reference statistical source for the foreign population.

In the case of municipalities with 45,000 inhabitants and over, results are also offered by districts.

For the period 2000–2022, the Municipal Population Register also offers data on the foreign population. For the years 2021 and 2022, both the Municipal Population Register and the Population Census offer data on the foreign population, but from 2021 the Population Census is considered the reference statistical source for the foreign population.
