Population of the Basque Country by province, according to groups of countries of nationality.

Knowing and quantifying the population in relation to studies, level of Basque, activity and mobility of people who reside in the Basque Country, as well as information on housing, requires various statistical sources. On the one hand, population counts have been carried out decennially, via the Population and Housing Censuses, and the Population and Housing Statistics, in an inter-census period; on the other hand, through the various municipal statistics (on Inhabitants, Housing, Education and Active population). Furthermore, using the administrative registries of the Municipal Register of Inhabitants as sources, there is a renewal of the municipal demographic information and the different characteristics.
