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.

Catalonia
According to the linguistic census held by the Government of Catalonia in 2013, Spanish is the most spoken language in Catalonia (46.53% claim Spanish as "their own language"), followed by Catalan (37.26% claim Catalan as "their own language"). In everyday use, 11.95% of the population claim to use both languages equally, whereas 45.92% mainly use Spanish and 35.54% mainly use Catalan. There is a significant difference between the Barcelona metropolitan area (and, to a lesser extent, the Tarragona area), where Spanish is more spoken than Catalan, and the more rural Catalonia, where Catalan clearly prevails over Spanish.
