The Basic Demographic Indicators constitute a collection of indicators that summarize the historical evolution of the behaviour of basic demographic phenomena in Spain (birth rate, fertility, mortality and marriage rate), of the divorces, of the migratory movements, and of the growth and structure of the population resident in the country. They are calculated from the results of the statistics of Births, Deaths and Marriages, of the Statistics on Annulments, Separations and Divorces, of the Statistics on migration and of the Figures of population resident in Spain of reference.

National, Autonomous and provincial demographic indicators are published, calculated according to basic demographic characteristics, such as sex, age and nationality (Spanish/foreign). The series of results started in 1975, although the breakdown by nationality has only been available since 2002, divorce indicators begin in 2005 and the indicators on migration movement started in 2008.
