Methodology

    1. Concepts

    Foreign population
    This term refers to the nationality of the person. According to Law 8/2000 on Foreign Persons dated the 22nd of December 2000, a foreigner is anyone who is not a national and whose nationality follows that of their parents; that is, in Spain nationality is determined by blood right (jus sanguinis). In other countries, nationality is determined by birthright (jus soli), that is, one is considered a national of a given country for the mere fact of having been born in that country. This is the case of the United States.
    International migrant
    In accordance with the recommendations from the United Nations Statistics Division, an international migrant is a person who moves to live in another country other than their usual country of residence for at least one year. For this reason, not every foreign person is an immigrant.
    Place of residence
    This is the territorial area where the person usually resides. Temporary trips do not change the usual place of residence.
    Nationality
    Nationality refers to each person's legal citizenship. A citizen is a person who holds legal nationality in the country where they live, and a foreigner is a person who is not a national of that country. A person's country of nationality is not necessarily the same as their place of birth.
    Geographical origin
    In this information, the country of nationality is considered the country of origin.

    2. Statistical source

    The source of this information is the Population and Housing Census on 1 January every year. The Population Census is produced annually, starting in 2021, by combining administrative records, of which the Population Register is the main one. When preparing the Population Census, the statistical treatments and procedures applied, including comparisons with other sources, make it possible to offer a more accurate statistical count of the population and its characteristics than the Population Register.
