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.
Language policies of Francoist Spain
Language politics in Francoist Spain centered on attempts in Spain under Franco to increase the dominance of the Spanish language (Castilian) over the other languages of Spain. The regime of Francisco Franco had Spanish nationalism as one of its bases. Under his dictatorship, the Spanish language (known in some parts of Spain as "castellano", i.e., "Castilian") was declared Spain's only official language.
