Italian is an official language of Italy and San Marino and is spoken fluently by the majority of the countries' populations. Italian is the third most spoken language in Switzerland (after German and French), though its use there has moderately declined since the 1970s. It is official both on the national level and on regional level in two cantons: Ticino and the Grisons. In the latter canton, however, it is only spoken by a small minority, in the Italian Grisons. Ticino, which includes Lugano, the largest Italian-speaking city outside Italy, is the only canton where Italian is predominant. Italian is also used in administration and official documents in Vatican City.
