PROJ Population Projections

The purpose of the Population Projections is to evaluate future population figures of Catalonia, as classified by sex, age and the territorial distribution. The Projections are based on the Population Census, to which hypotheses regarding the future evolution of fertility, mortality and migration are applied.

The Population Projections are updated approximately every five years and provide information classified by sex and age year-over-year. As for the territory, they provide results for Catalonia, the areas of the territorial Plan, the provinces, the counties and Aran.

Every five years Idescat produces a series of statistics which are categorised as Population Projections, in accordance with different hypotheses based on demographic information. Idescat firstly updates the Population Projections by sex and age, and then, by sex and age, and then, the municipal population projections, the household projections, the active population projections and the school-age population projections.
