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.
Principality of Catalonia
Today, Catalan is one of the three official languages of autonomous community of Catalonia, as stated in the Catalan Statute of Autonomy; the other two are Spanish, and Occitan in its Aranese variety. Catalan has no official recognition in "Northern Catalonia". Catalan has official status alongside Spanish in the Balearic Islands and in the Land of Valencia (where it is called "Valencian"), as well as Algherese Catalan alongside Italian in the city of Alghero and in Andorra as the sole official language.
