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.
Catalan Countries
Catalan Countries (, ) refers to those territories where the Catalan language, or a variant of it, is spoken. They include the Spanish regions of Catalonia, Valencia, the Balearic Islands and parts of Aragon and Murcia, as well as Roussillon in France, the Principality of Andorra, and the city of Alghero in Sardinia (Italy). In the context of Catalan nationalism, the term is sometimes used in a more restricted way to refer to just Catalonia, Valencia and the Balearic Islands. The Catalan Countries do not correspond to any present or past political or administrative unit, though most of the area belonged to the Crown of Aragon in the Middle Ages. Parts of Valencia (Spanish) and Catalonia (Occitan) are not Catalan-speaking.
