EP Population Estimates

Population Estimates are the statistics that, on a semiannual basis, provide a count of the resident population in Catalonia as of 1 January and 1 July since 1981. Population Estimates allow the calculation, each year, of various demographic and socioeconomic indicators. They provide data on residents in Catalonia, the provinces, the areas of the Territorial Plan, and the counties and Aran, classified by sex and age. Until 2020 they provide data for municipalities with 50,000 inhabitants and over, and from 2021 onwards they provide data for all municipalities.

Population Estimates also provide information on the components of population growth for each year (births, deaths, internal migration, and international migration).

From 2021 onwards, Population Estimates as of 1 January each year correspond to the Population Census data (which became annual) on the same date. Population Estimates as of 1 July are calculated based on the Population Estimates as of 1 January of two consecutive years.

Idescat produces advanced Population Estimates as of 1 January and 1 July, with the aim of providing a calculation of the population with minimal delay relative to the reference date. The results remain valid until they are replaced, each year, by the definitive Population Estimates.
