Wolfsburg is the fifth largest city in the German state of Lower Saxony. Located on the River Aller. It lies about 75 km (47 mi) east of Hanover and 230 km (143 mi) west of Berlin.
In 2013, Wolfsburg ranked as the richest city in Germany with a GDP per capita of $128,000 due to its thriving auto industry.
The centre of Wolfsburg is unique in Germany. Instead of a medieval town center, Wolfsburg features a new and modern attraction called the Autostadt. The old part of the town Alt Wolfsburg (de) shows some manor buildings in traditional framework style. Atop a hill by the River Aller is the Wolfsburg Castle.
From about 1,000 inhabitants in 1938 the population of the city increased to 25,000 in 1950 and doubled to 50,000 until 1958. On 1 July 1972 the population of Wolfsburg first went beyond the mark of 100,000 because of the suburbanization of several villages which made Wolfsburg a major city. In 1973 the population reached its highest level: 131,971. At the end of December 2010 121,451 people were registered with their principal residence in Wolfsburg. Until the end of 2012 this number climbed up to 123,144.
In 1946, the military government of the British zone of occupation established a communal constitution following the British example. After this, citizens voted for a council which elected a volunteer mayor/ lord mayor as the city's leader and representative. After 1946, the council elected a full-time director to lead the city council. In 2001, the city council's dual leadership was abolished. It is led by a full-time lord mayor who is also the city's representative, Klaus Mohrs. Since 2001, citizens directly elect the lord mayor. The council still has its own chairperson elected by the council's constitutive conference after every local election.
