The population of Catalonia on 1 January 2017 amounted to 7,477,131 inhabitants, according to the advance of Population Estimates put together by Idescat. This figure represents a year-over-year increase of 28,799 inhabitants (0.4%) compared to 2016, thus confirming an increase in population for the second consecutive year.
By territory, the Metropolitan Area saw the greatest increase (27,295 inhabitants), with a growth of 0.6%. By contrast, Les Terres de l'Ebre was the area with the greatest loss of population (-1,372 inhabitants), with a decrease of 0.8%.I
The Population Estimates is a statistical operation performed every year, which provides a headcount of the population residing in Catalonia. They offer data of the residents in Catalonia, provinces, areas of the Territorial Plan, counties and Aran, and municipalities of 50,000 inhabitants or more, classified by sex and age. The results are coherent with the Population Census and the demographic movement (births, deaths and migration). The Population Estimates allow different demographic and socio-economic indicators to be calculated each year.
The advance was calculated based on the Population Estimates from 1 January 2016 and estimated data for demographic flows for 2016. The advanced results are available for Catalonia, its provinces and all 8 areas of the Territorial Plan.
The results will be valid until December, when Idescat will replace them with the definitive postcensal estimates, which are calculated once the figures for births, deaths and migrations are made available for the reference year.
