Definition of concepts

Natural population change
Increase or decrease in the population, which is obtained from the difference between births and deaths, for a specific period and territorial region.

Methodological aspects

The source for the natural population movement is declarations made in the Civil Register at the moment of registering a birth or death, when a statistical report of the event is provided.

Until 2011, the data refers to the registrations made in Catalonia of people who reside there. From 2012 onwards, it includes all events involving residents in Catalonia who have been registered in other autonomous communities.

The territorial breakdown is made by places of residence: for births, that of the mother; for deaths, that of the deceased.

Current Territorial Distribution

At present, Catalonia is divided into 41 counties, 1 singular territorial entity (Aran) and 8 areas of the Territorial Plan, according to the latest territorial changes, which affect the areas of El Penedès and the Central Counties, Aran and El Moianès.
