Population estimates. 2019. Definitive data

The resident population of Catalonia was 7,619,494 as of 1 January 2019, an increase of 75,669 inhabitants on the previous year, according to definitive Population Estimates data. International migration was the only factor that contributed to population growth in 2018 (81,443 people), as the rest of the factors are negative: the net migration with the rest of Spain (−2,689 people) and, for the first time since 1942, natural growth (−2,996 people).

The ageing process of the Catalan population continues and the percentage of the population aged 65 and over has rose from 18.8% in 2018 to 18.9% in 2019. The ageing index for Catalonia is 121.6 people over 65 years of age for every 100 people under 15, and this is the result of the combination of a low birth rate and high life expectancy.

The territorial analysis shows that in 2018 the population increased in 34 counties and Aran, while it fell in 7 counties. The counties with the largest growth figures in relative terms were El Baix Penedès (24.2‰), La Cerdanya (20.5‰), La Garrotxa (15.9‰) and El Tarragonès (15.2‰). In contrast, the counties that lost the most population in relative terms were La Conca de Barberà (−8.1‰) and La Ribera d'Ebre (−5.2‰).

The international net migration was positive in all counties and Aran. The county of Barcelonès stood out with the highest balance (41,080 people) followed by El Vallès Occidental (6,435). The internal migratory balance (migrations to and from the rest of Catalonia and the rest of Spain) was positive in 28 counties, and of these, the most prominent were El Maresme (2,144) and El Baix Penedès (1,526). As for natural growth, births outstripped deaths in 7 counties and Aran. El Vallès Occidental (987) and El Gironès (499) are the counties with the greatest natural growth.

These data replace the provisional data published in May and expand the territorial disaggregation.
