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.
Spaniards
Spaniards are a Romance ethnic group and nation. They are indigenous to Spain and share a common Spanish culture, history, ancestry, and language. Within Spain, there are a number of nationalisms and regionalisms, reflecting the country's complex history and diverse culture. Although the official language of Spain is commonly known as "Spanish", it is only one of the national languages of Spain, and is less ambiguously known as Castilian, a standard language based on the medieval romance speech of the early Kingdom of Castile in north-central Spain and the Mozarabic dialect of the Taifa of Toledo which was incorporated by the former in the 11th century. There are several commonly spoken regional languages, most notably Basque (a Paleohispanic language), Catalan and Galician (both Romance languages like Castilian). There are many populations outside Spain with ancestors who emigrated from Spain and who share a Hispanic culture; most notably in Hispanic America.
