Its larger metropolitan area has a population of nearly 2.9 million, representing nearly one-third of the country's population. Vienna is the cultural, economic, and political center of the country, the fifth-largest city by population in the European Union, and the most-populous of the cities on the Danube river.

Bavarian, alternately Austro-Bavarian, is a major group of Upper German varieties spoken in the southeast of the German language area, including the German state of Bavaria, most of Austria and the Italian region of South Tyrol. Prior to 1945, Bavarian was also prevalent in parts of the southern Sudetenland and western Hungary. Bavarian is spoken by approximately 12 million people in an area of around 125,000 square kilometres (48,000 sq mi), making it the largest of all German dialects. In 2008, 45 percent of Bavarians claimed to use only dialect in everyday communication.
