those who declare themselves as a distinct ethnic group with their own language and those who identify themselves as a Croatian sub-ethnic group. The latter are represented in Serbia by the Croat National Council, and the former by the Bunjevac National Council. Not all Croats in Serbia have Bunjevac or Sokac origins. The number of Croats in Serbia was somewhat larger in previous censuses that were conducted between 1948 and 1991. Proponents of a separate Bunjevac nation argue that the number of Croats may have been smaller at that time, as the communist authorities counted in the people to as Croats, who self-declared as Bunjevac or Sokac. Robert Skenderović emphasizes that already before 1918 and the Communist rule, Bunjevci have made strong efforts to be recognized as part of the Croatian people. The largest recorded number of Croats in a census was in 1961 when there were 196,409 Croats (including Bunjevci and Šokci) in the Socialist Republic of Serbia (around 2.57% of the total population of Serbia at the time). Since 1961 census, the Croat population in Serbia is in a constant decrease. This is caused by various reasons, including economic emigration, and ethnic tensions of the Yugoslav wars during the 1990s, more specifically the 1991-1995 War in Croatia. During this war-time period, Croats in Serbia were under pressure from the Serbian Radical Party and some Serb refugees from Croatia and Bosnia and Herzegovina to move to Croatia. In that time, a transfer of population occurred between Croats from Serbia and Serbs from Croatia. Based on an investigation by the Humanitarian Law Fund from Belgrade in the course of June, July, and August 1992, more than 10,000 Croats from Vojvodina exchanged their property for the property of Serbs from Croatia, and altogether about 20,000 Croats left Serbia. According to other estimations, the number of Croats who have left Serbia under political pressure of the Milošević's regime might be between 20,000 and 40,000. According to Petar Kuntić of Democratic Alliance of Croats in Vojvodina, 50,000 Croats were pressured to move out from Serbia during the Yugoslav wars. * - excluding Kosovo Croats in Vojvodina Croats are the fourth largest ethnic group in the Vojvodina province, an autonomous province located in the northern part of the country which traditionally fosters multilingualism, multiculturalism and multiconfessionalism. According to the 2011 census, there are 47,033 Croats living in Vojvodina. In the 1990s, during the Milošević
