Població de Catalunya georeferenciada a 1 de gener

Idescat provides data on the georeferenced population of Catalonia as of 1 January of the reference year, including the variables sex, age, nationality, and place of birth.

Until 2022, the georeferenced population corresponded to the population recorded in the Statistical Population Register as of 1 January. From 2023 onwards, the population as of 1 January of each year corresponds to the data from the Population Census (which becomes annual).

Georeferencing individuals involves assigning each person their position (x, y) on the map.

The individuals are aggregated to be presented on a multiresolution grid (62.5 m, 125 m, and 250 m), which is compatible with the standard European grid (EEA reference grid - European Environment Agency). To preserve statistical confidentiality, data is not reported for any grid where the total number of individuals is fewer than 17.

These maps can be crossed with users’ own geometries in order to obtain the data on the population residing within any specific geometry and the data on the distribution of population densities across Catalonia, among others.

The information is provided in a ZIP folder containing the files in Shapefile format, along with the associated methodology in PDF format.
