Notas:
Procedimientos de revisión de resultados de la operación estadística IDB han detectado discrepancias en los datos en esta tabla. Corrigiéndose a fecha 9 de febrero de 2022 para los años comprendidos entre 2002 y 2006.
The results of 2012 to 2020 (nationals, by autonomous communities and by provinces) have been updated with the Intercensal population estimates.
The results of 2021 (nationals, by autonomous communities and by provinces) have been updated with the annual census on 1 January, 2021 and 1 January, 2022.
Disaggregation by nationality is available as of 2002. 
For the provisional data in registers in which the "order of birth" does not appear, this is imputed with the distribution on the average values over the past three years.
