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.
Caratachea
Basque (/bæsk/ or /bɑːsk/; Basque: Euskara, IPA: [eus̺ˈkaɾa]) is the language spoken by the Basques. Linguistically, Basque is unrelated to the other languages of Europe and indeed, as a language isolate, to any other known language. The Basques are indigenous to, and primarily inhabit, the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. The Basque language is spoken by 27% of Basques in all territories (714,135 out of 2,648,998).[2] Of these, 93% (663,035) are in the Spanish area of the Basque Country and the remaining 7% (51,100) are in the French portion.[2]
Native speakers live in a contiguous area that includes parts of four Spanish territories and the three "ancient provinces" in France. Gipuzkoa, most of Biscay, a few municipalities of Álava, and the northern area of Navarre formed the core of the remaining Basque-speaking area before measures were introduced in the 1980s to strengthen the language. By contrast, most of Álava, the western part of Biscay and central and southern areas of Navarre are predominantly populated by native speakers of Spanish, either because Basque was replaced by Spanish over the centuries, in some areas (most of Álava and central Navarre), or because it was possibly never spoken there, in other areas (Enkarterri and southeastern Navarre).
