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.
Spanish Sign Language
From a strictly linguistic point of view, Spanish Sign Language refers to a sign language variety employed in an extensive central-interior area of the Iberian Peninsula, having Madrid as a cultural and linguistic epicenter, with other varieties used in regions such as Asturias, Aragon, Murcia, parts of western Andalusia and near the Province of Burgos.
