The demographic characteristics of the population of Croatia are known through censuses, normally conducted in ten-year intervals and analysed by various statistical bureaus since the 1850s. The Croatian Bureau of Statistics has performed this task since the 1990s. The latest census in Croatia was performed in autumn of 2021. According to final results published on 22 September 2022 the permanent population of Croatia at the 2021 census had reached 3.87 million. The population density is 68.7 inhabitants per square kilometre, and the overall life expectancy in Croatia at birth was 78,2 years in 2018. The population rose steadily from 2.1 million in 1857 until 1991, when it peaked at 4.7 million. Since 1991, Croatia's death rate has continuously exceeded its birth rate; the natural growth rate of the population is negative. Croatia is in the fourth stage of the demographic transition. In terms of age structure, the population is dominated by the 15 to 64 year‑old segment. The median age of the population is 43.4, and the gender ratio of the total population is 0.93 males per 1 female.

World War II in the Kingdom of Yugoslavia began on 6 April 1941, when the country was invaded and swiftly conquered by Axis forces and partitioned among Germany, Italy, Hungary, Bulgaria and their client regimes. Shortly after Germany attacked the USSR on 22 June 1941, the communist-led republican Yugoslav Partisans, on orders from Moscow, launched a guerrilla liberation war fighting against the Axis forces and their locally established puppet regimes, including the Axis-allied Independent State of Croatia (NDH) and the Government of National Salvation in the German-occupied territory of Serbia. This was dubbed the National Liberation War and Socialist Revolution in post-war Yugoslav communist historiography. Simultaneously, a multi-side civil war was waged between the Yugoslav communist Partisans, the Serbian royalist Chetniks, the Axis-allied Croatian Ustaše and Home Guard, Serbian Volunteer Corps and State Guard, Slovene Home Guard, as well as Nazi-allied Russian Protective Corps troops.
