The data published today are final. All results of this operation are available on INEbase.
Since 2015 INE has published statistics on Acquisition of Spanish Citizenship of Residents (EANER), with data from 2013 onwards. Its main purpose is to provide the number of persons who, having their habitual residence in Spain, acquire Spanish nationality during the reference year, having previously had the nationality of another country or the condition of statelessness. Therefore, persons who have acquired Spanish nationality while residing in other countries are excluded as well as those processes in which Spanish nationality is obtained by reason of origin (by simple presumption or adoption) or by consolidation (possession of status of those who already act as Spaniards).
This operation is based on the statistical treatment of the registration of nationality files in the Civil Registry.
Acquisitions of nationality by persons residing in the different regions of Spain are published, according to sex, age, previous nationality, country of birth and mode of acquisition. In addition, starting in 2022 four new disaggregation variables have been included for data with a reference year from 2019 onwards: year of arrival in Spain, level of education, relationship with economic activity and occupation.

INE statistics are produced in accordance with the Code of Good Practice for European Statistics. More information on Quality at INE and the Code of Best Practices.
