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.

According to Ethnologue, about 18,000 deaf Catalans use Catalan Sign Language (LSC, "Llengua de signes catalana"). Since, like other deaf sign languages, LSC has no generally used written form, there is no literacy data.
