Houses of the Basque Country by territorial scope by type.

The knowledge and quantification of the population and families residing in the Basque Country requires various statistical sources. On the one hand, population and family counts have been carried out decennially through the Population and Housing Census, as well as by Population and Housing Statistics (SPV) in the intercensal period; on the other hand, through the Municipal Population Update (APM) and using as main sources the administrative records of the Municipal Register of Inhabitants, municipal demographic information is renewed.
