Population and Housing Census. 2024. Advance

The population of Catalonia increased by 110,268 inhabitants in 2023 and on 1 January 2024 it stood at 8,012,231 inhabitants according to advanced data from the Population Census. In relative terms, in 2023 the population grew by 1.4%.

In 2023, the population grew in 37 counties and Aran. It should be borne in mind that the results for El Solsonès and La Segarra are affected by the change of county designation of Torà and Biosca, just as those for Osona are affected by the creation of El Lluçanès.

For the first time, Idescat is providing census data on the population of the county of El Lluçanès, created in May 2023. As of 1 January 2024, it had 5,718 inhabitants of whom 2,877 were men and 2,841 were women.

The counties with the greatest growth in relative terms were El Baix Penedès (2.3%) and El Gironès (2.0%), in addition to El Solsonès (11.6%, affected by the new county division), and there are 10 more counties which are above the average for Catalonia. Conversely, La Terra Alta (−0.2%) and El Pallars Jussà (−0.2%) are the counties that have lost population, in addition to La Segarra (−5.3%) and Osona (−2.1%) affected by the territorial changes.

Among municipalities with 10,000 inhabitants and over, the main increases in relative terms were recorded in Mont-roig del Camp (3.7%), Calafell (3.6%) and Cunit (3.3%) and the main decreases in Martorell (−0.6%) and in L'Escala, Ripoll and Sant Quirze del Vallès (−0.4%).

Idescat is publishing the advanced results of the 2024 Population Census. It provides information on the population by sex for Catalonia, provinces, areas of the Territorial Plan, counties and municipalities.
