Trentino-Alto Adige/Südtirol is an autonomous region of Italy, located in the northern part of the country. The region has a population of 1.1 million, of whom 62% speak Italian as their mother tongue, 30% speak South Tyrolean German and several foreign languages are spoken by immigrant communities. Since the 1970s, most legislative and administrative powers have been transferred to the two self-governing provinces that make up the region: the province of Trento, commonly known as Trentino, and the province of Bolzano, commonly known as South Tyrol. In South Tyrol, German remains the sizeable majority language.
