The war in Bosnia and Herzegovina resulted in major changes in the country, some of which were quantified in a 1998 UNESCO report. Some two million people, about half the country's population, were displaced. In 1996 there were some 435,346 ethnic Serb refugees from the Federation in Republika Srpska, while another 197,925 had gone to Serbia. In 1991, 27% of the non-agricultural labour force was unemployed in Bosnia and this number increased due to the war. By 2009, the unemployment rate in Bosnia and Herzegovina was estimated at 29%, according to the CIA's "The World Factbook". Republika Srpska's population of Serbs had increased by 547,741 due to the influx of ethnic Serb refugees from the Federation of Bosnia and Herzegovina and the former unrecognised state of the Republic of Serbian Krajina in the new Republic of Croatia.
