Languages of Catalonia
There are four languages with official status in Catalonia (an autonomous community of Spain): Catalan; Spanish- which is official throughout Spain; Aranese, a dialect of Occitan spoken in the Aran Valley; and Catalan Sign Language. Many other languages are spoken in Catalonia as a result of recent immigration from all over the world.

With the exception of Andorra, Catalan as spoken outside of Catalonia may be diglossic in various grades, from highly to barely diglossic. Diglossia in Catalan is typically stronger in some metropolitan areas than rural or sparsely populated areas.
