2007 administrative reformEdit

On January 1, 2007, due to Kommunalreformen ("The Municipal Reform" of 2007), the former Sønderborg municipality, located on Als and the mainland, was combined with Augustenborg (on Als), Broager, Gråsten, Nordborg (on Als), Sydals (on Als), and Sundeved municipalities to form a new Sønderborg municipality. The municipality shares the number one position with Lolland Municipality of being formed through the merger of most former municipalities in the reform of 2007:seven (7). The former Sønderborg municipality covered an area of 54 km2 (21 sq mi), and had a population of 30,555 (2005). Its last mayor was Arne Peder Hansen, a member of the Venstre (Liberal Party) political party.


The municipality is home to two of the major industrial companies in Denmark: Danfoss and Linak.

North Schleswig GermansEdit

Sønderborg Municipality is home to the only officially recognised ethno-linguistic minority of Denmark proper, the North Schleswig Germans.

In these four municipalities, the German minority enjoys certain linguistic rights in accordance with the European Charter for Regional or Minority Languages.
