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.
Spanish naming customs
The Catalan-speaking territories also abide by the Spanish naming customs, yet usually the discrete surnames are joined with the word "i" ("and"), instead of the Spanish "y", and this practice is very common in formal contexts. For example, the former president of the Generalitat de Catalunya (Government of Catalonia) is formally called "El Molt Honorable Senyor Carles Puigdemont i Casamajó". Furthermore, the national language policy enumerated in article 19.1 of Law 1/1998 stipulates that "the citizens of Catalonia have the right to use the proper regulation of their Catalan names and surnames and to introduce the conjunction between surnames".
