The purpose of the Population Projections statistical operation is to evaluate future population figures of Catalonia, as classified by sex, age and area of residence. The projection is based on the Post-Census Estimate and the statistics on births, deaths and migratory movements.
Every five years Idescat produces a series of statistics which are categorised as population projections, according to different demographically-based hypotheses. It firstly updates the population projections by sex and age followed by the school age population projections and, finally, the projections regarding the active population.
