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.
Names given to the Spanish language
In the regions where regional languages are spoken, there is obviously a daily need to make the contrast between the national language and the regional language and so the national language is most often referred to as Castilian, particularly in the regional languages themselves (for example, "espanyol" is virtually never used to refer to the language in Catalan: "castellà" is used instead; in Basque, the name of the language is "gaztelania" or "gaztelera", never "espainiera"; and in Galician, the most commonly used term is "castelán" rather than "español"). That is often mirrored by educated English-speakers to refer to the linguistic situation in Spain.
