Passage: The population decrease was also a result of the Croatian War of Independence. During the war, large sections of the population were displaced and emigration increased. In 1991, in predominantly occupied  areas, more than 400,000 Croats were either removed from their homes by the Croatian Serb forces or fled the violence. During the final days of the war in 1995, more than 100,000 Serbs voluntarily fled the country before the arrival of Croatian forces during Operation Storm to avoid being brought to justice for their unjustifiable acts committed during the Croatian War for Independence. After the war, the number of displaced persons fell to about 250,000. The Croatian government has taken care of displaced persons by the social security system, and since December 1991 through the Office of Displaced Persons and Refugees.Most of the territories which were abandoned during the Croatian War of Independence were settled by Croat refugees from Bosnia and Herzegovina, mostly from north-western Bosnia, while some of the displaced people returned to their homes.According to the 2013 United Nations report, 17.6% of Croatia's population were foreign-born immigrants. Croatia is inhabited mostly by Croats (90.4%) and is ethnically the most homogeneous of the six countries of former Yugoslavia. Minority groups include Serbs (4.4%), Bosniaks, Italians, Albanians, Roma, Hungarians, Slovenes, Czechs, Montenegrins, Macedonians, Yugoslavs, and others (1.98%).
