Languages of Catalonia
According to the official government of Catalonia, Catalan is the second most spoken language of the region, after Spanish (over 35% of Catalans use exclusively Catalan as their first language, while 11% of Catalans use equally both Catalan and Spanish). It is the most spoken language in many comarques of Catalonia, with the exception of the Barcelona metropolitan area (Barcelonès plus surrounding comarques) and Camp de Tarragona. Catalan is a compulsory subject in schools and enjoys equals rights with Spanish throughout Catalonia.
National and regional identity in Spain
Aragon has its own language, Aragonese, with about 25,000 speakers, mainly in the mountainous north while Castilian is spoken in the southern two-thirds and Catalan is spoken along the eastern strip. Because of the prevalence of Castilian and the presence of Catalan, the language does not play as large a role in Aragonese identity as in some other locations, but it does enjoy some official recognition.
