Internal immigration rate

Methodological aspects

Residential Variation Statistics (RVS) are compiled by the INE from information regarding registrations and delistings due to changes of residence registered in the Municipal Registers, with variation dates from the reference year.

Migratory movement refers to the displacement of an individual due to a change in residence, as well as the characteristics of this migration. The information contained comprises only inter-municipal changes and, as such, changes in residence within the same municipality are excluded.

Yearly residential variation statistics do not refer to the number of people changing residence, but rather to the number of changes made, as a citizen may change residence from one municipality to another more than once a year.

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.
