The Yugoslav government estimated the number of human losses during World War II in Yugoslavia at 1,706,000. This figure was submitted to the International Reparations Commission in Paris in 1946. The Commission then requested a documented estimate of the number of casualties. The Yugoslav government gave the task of providing a "significant, but scientifically and statistically founded" death toll to a mathematician of the Federal Bureau of Statistics. The results of this research were demographic losses, encompassing deaths during the war, declining birth-rates, and migration, of around 1,700,000. Deputy Prime Minister Edvard Kardelj presented the demographic losses as actual war losses to support Yugoslavia's request for reparations. This number, equalling to 10.8% of its population, stayed the official estimate in Yugoslavia during its existence.
