With an area of 3,263 km2 (1,260 sq mi) and a population of about 126,933, it is the smallest, least populous, and least densely populated region of Italy. It is the only Italian region which has no provinces (the province of Aosta was dissolved in 1945). Provincial administrative functions are provided by the regional government. The region is divided into 74 comuni (communes).
Italian and French are both official, though the native population speaks also Valdôtain, a form of Franco-Provençal (Arpitan), as home language. In 2001, 96.01% of the Valdostan population reported knowing Italian, 75.41% French, 55.77% the Valdostan Franco-Provençal patois, and 50.53% all of them.
The regional capital is Aosta.
