Spain
As a percentage of the general population of all Spain, Spanish is natively spoken by 74%, Catalan by 17%, Galician by 7% and Basque by 2% of all Spaniards. Occitan is spoken by less than 5,000 people, only in the small region of "Val d'Aran".
Other Romance minority languages, though not official, have special recognition, such as the Astur-Leonese language ("asturianu", "bable" or "llionés") and Aragonese ("aragonés") in Aragon.
Bilingual education
In addition to Castilian Spanish being the primary official language of Spain, the kingdom also has several co-official regional languages which enjoy equal and unbiased constitutional protection and promotion: Catalan/Valencian (in Catalonia, Valencia and the Balearic Islands), Galician (in Galicia), Basque (in the Basque Country and the northern zone of Navarre) and Aranese (in Val d'Aran, Catalonia).
