I am looking for census results

The first reliable and systematic census operations in the Austro-Bohemian lands (including the numbering of all houses) were carried out from the 1770s, and later supervised, by the military, the main aim being to facilitate recruitment for the army. Hungary was largely exempt.

Detailed results for districts, towns, manors let alone for individual households have not been preserved. Vestiges may survive in local archives.

Registers of residents, obligatory in larger agglomerations from the 18^th century onwards and kept by the local police authorities, are useful if often fragmentary alternative sources. They can be found in municipal archives. The Viennese register covers the period 1904–1975.

The Tafeln zur Statistik der Österreichischen Monarchie (published in print between 1827 and 1846, but excluding Hungary) contain statistical data which are irrelevant for genealogical research.

Following the “Volkszählungsgesetz” of 1857 the census was to be conducted by civil authorities.
