Geography Pinneberg is located in southwestern Schleswig-Holstein. As of the 2021 federal election, it is coterminous with the Pinneberg district. This includes the small Heligoland islands (1.7 km2, population 1,309) off the North Sea coast.
History Pinneberg was created in 1949. Until 1965, it was constituency 12 in the number system; from 1965 to 1976 it was constituency 9. Since 1976, it has been constituency 7. It has been coterminous with the Pinneberg district since its creation.
Members The constituency was held by the Social Democratic Party (SPD) during the inaugural term of the Bundestag, during which time it was represented by Anni Krahnstöver. It was won by the Christian Democratic Union (CDU) in 1953, and represented by Wilhelm Goldhagen (until 1961) and Rolf Bremer. In 1969, it was won again by the SPD, and represented in turn by Hans-Ulrich Brand and Hermann P. Reiser, who each served for a single term. Party fellow Reinhard Ueberhorst represented it from 1976 until 1983, when it was won by Ingrid Roitzsch of the CDU. She was succeeded by Gert Willner from 1994 to 1998 before the constituency was again won by the SPD. Ernst Dieter Rossmann represented it for two terms. Ole Schröder of the CDU served from 2005 to 2017, before being succeeded by party fellow Michael von Abercron in 2017. Ralf Stegner was elected for the SPD in 2021.
With the exception of the 1949 election, Pinneberg can be considered Germany's bellwether constituency, having always voted for the party that would win the chancellorship. (In 1969, 1976 and 1980 elections, CDU-CSU came first, but SPD formed the government.)
