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.
Spaniards
Spaniards are a Romance ethnic group and nation. They are indigenous to Spain and share a common Spanish culture, history, ancestry, and language. Within Spain, there are a number of nationalisms and regionalisms, reflecting the country's complex history and diverse culture. Although the official language of Spain is commonly known as "Spanish", it is only one of the national languages of Spain, and is less ambiguously known as Castilian, a standard language based on the medieval romance speech of the early Kingdom of Castile in north-central Spain and the Mozarabic dialect of the Taifa of Toledo which was incorporated by the former in the 11th century. There are several commonly spoken regional languages, most notably Basque (a Paleohispanic language), Catalan and Galician (both Romance languages like Castilian). There are many populations outside Spain with ancestors who emigrated from Spain and who share a Hispanic culture; most notably in Hispanic America.
