Languages of Catalonia
According to the government of Catalonia, Spanish, locally known as Castilian, is currently the most spoken language in Catalonia (45.9% daily users of Spanish vs. 35.6% daily users of Catalan vs. 11% daily users of both Spanish and Catalan) and especially in the Barcelona metropolitan area, as well as native language and usual language of many Catalan citizens. This language is widely prevalent in the press, cinema and in daily life.
Catalonia
Today, Catalan is the main language of the Catalan autonomous government and the other public institutions that fall under its jurisdiction. Basic public education is given in Catalan, except for two hours per week of Spanish medium instruction. Businesses are required to display all information (e.g. menus, posters) at least in Catalan, under penalty of fines. There is no obligation to display this information in either Occitan or Spanish, although there is no restriction on doing so in these or other languages. The use of fines was introduced in a 1997 linguistic law that aims to increase the public use of Catalan and defend the rights of Catalan speakers.
