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.
National and regional identity in Spain
As of 2011, 95% of the population were able to understand Catalan, and 73% could speak it. In 2007, 32% named Catalan as the primary language that they actually did speak, against 50% for Spanish (Castilian); 7% spoke the two languages equally. The ethnolinguistic composition of the population has been heavily affected by extensive immigration from non-Catalan speaking parts of Spain, much of it associated with rapid growth in industry, since the late 19th century and more particularly between 1950 and 1975.
