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.
Iberian Romance languages
Originating in Iberia, the most widely spoken Iberian Romance languages are Castilian (Spanish), Portuguese, Catalan and Galician. These languages also have their own regional and local dialects. Based on mutual intelligibility, Dalby counts seven "outer" languages, or language groups: Galician-Portuguese, Spanish, Astur-Leonese, "Wider"-Aragonese, "Wider"-Catalan, Provençal+Lengadocian, and "Wider"-Gascon.
