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.
Valencian Community
Spanish (Castilian or "castellano") has official status in all of Spain, including the Valencian Community. Aside from it, the Statute of Autonomy recognizes Valencian as the language proper to the Valencian people ("llengua pròpia"), and commends its protection and regulation to the Acadèmia Valenciana de la Llengua (AVL) under the Generalitat Valenciana. Valencian is also official in the autonomous communities of Catalonia and the Balearic Islands, where it is called Catalan.
