Demographics of the Kingdom of Yugoslavia

For demographics of Yugoslavia between 1945 and 1992, see Demographics of the Socialist Federal Republic of Yugoslavia.

The Kingdom of Yugoslavia existed between its creation in 1918 until its occupation and partition by Axis powers in World War II. The first census in 1921 enumerated 11,984,911, while the second and last census in 1931 enumerated 13,934,038 people. While both censuses grouped ethnic groups according to their mother tongue, the latter did not record separate constituent nationalities and reported all "Serbo-Croato-Slovene" speakers as "Yugoslavs".
