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.
Andalusia
Andalusian Spanish is one of the most widely spoken forms of Spanish in Spain, and because of emigration patterns was very influential on Latin American Spanish. Rather than a single dialect, it is really a range of dialects sharing some common features; among these is the retention of more Arabic words than elsewhere in Spain, as well as some phonological differences compared with Standard Spanish. The isoglosses that mark the borders of Andalusian Spanish overlap to form a network of divergent boundaries, so there is no clear border for the linguistic region.
