This article presents the Demographic history of Slovenia, with census results where available. See Demographics of Slovenia for a more detailed overview of the current demographics from 2002 census.
There are censuses for the years 1830, 1857, and 1869. Population censuses were then carried out every ten years, in 1880, 1890, 1900, 1910, 1921, and 1931.[1]
Slovenia was divided between the Austrian regions of Carniola, Austrian Littoral, Styria and Carinthia, not counting the Hungarian-owned Prekmurje region. In Styria, there were 342,013 Slovenians, or 38.72% of the population [2].
As a result of the rise of German nationalism, which entailed germanizing school networks, economic coercion, and language shift for economic or social reasons, the number of Slovenians in Slovenia went from 96% in 1846, 85.5% in 1880, 84.6% in 1890 and 87.3% in 1900 to 81.7% in 1910. These developments were particularly visible in southern Carinthia, today mostly a part of Austria, largely due to the developing tourist industry on the lakes of the Klagenfurt basin. Similar developments took place in the Prekmurje region, which was then a part of Royal Hungary, with Hungarian replacing German as the prestigious language.
