EP Population Estimates

The Population Estimates is a statistical operation performed every six months, which provides a headcount of the population residing in Catalonia on January 1 and July 1 since 1981. They offer data of the residents in Catalonia, provinces, areas of the Territorial Plan, counties and Aran and municipalities classified by sex and age. Until 2020, they offer data on municipalities of 50,000 inhabitants and more and from 2021 they offer data on all municipalities.

From 2021 onwards, the Population Estimates as of 1 January of each year correspond to the data of the Population Census (which becomes annual), on the same date. The Population Estimates as of 1 July are calculated based on the Population Estimates as of 1 January of 2 consecutive years.

Idescat prepares Advanced Population Estimates on 1 January and 1 July, with the aim of providing a calculation of the population with the minimum delay with respect to the reference date. The results remain valid until each year they are replaced by the final Population Estimates.
