The districts of Vienna (German: Bezirke) are the 23 named city sections of Vienna, Austria, which are numbered for easy reference. They were created from 1850 onwards, when the city area was enlarged by the inclusion of surrounding communities. For federal law, the districts of Vienna do not have the same tasks as the district offices (Bezirkshauptmannschaften) in other parts of Austria, since according to the federal constitution, the whole of Vienna is considered a single district after this definition.
The seats of Bezirksvorsteher (political district head) and Bezirksvertretung (district assembly)—both unique in Austria since the districts in the other eight states of the republic are mere administrative bodies—are located in the respective districts, with the exception of the 14th district, whose political representatives reside in the 13th district (to which much of the 14th had belonged until 1938). The Magistratisches Bezirksamt (district office of the city administration, not headed by the political district head) in four locations combines services for two districts:
Since 2002, in Austria, instead of the police the mayors are responsible for objects found in public places. In Vienna, the mayor has ordered the district offices to perform the functions police stations have performed concerning found objects until then. Since 2005, by federal law the districts in all of Austria are responsible for issuing passports and registering residents, tasks until then covered in Vienna by the Federal Police. The mayor of Vienna again has ordered the district offices of the Magistrat to perform these functions.
Optimizing overhead costs has gone farther with the Federal Police in Vienna. The 23 District Police Commands in 2002 have been reduced to 14 City Police Commands. Reducing the number of small districts by mergers, as happened in Berlin after the 1990 reunification of Germany, has not even been discussed in Vienna, since the district assemblies function as breeding factories for the political parties' representatives.
