The 1991 population census in Bosnia and Herzegovina was the last census of the population undertaken in the Socialist Republic of Bosnia and Herzegovina before the Bosnian War. It was conducted during the final week of March 1991. For the 1991 census there were 109 municipalities of which ten were part of Sarajevo. Usage As the next census of Bosnia and Herzegovina was not held until 2013, the 1991 census was used as the basis for institutionalized affirmative action practices in the country, which ensure equal or proportional representation of the country's "constituent peoples" (Bosniaks, Croats and Serbs) in public institutions. Due to the ethnic cleansing campaigns that took place during the 1992 to 1995 war, the data for ethnicity was expected to be highly inaccurate. Overall By municipality Absolute ethnic majority Relative ethnic majority NOTE: There seems to be a discrepancy in the above-listet numbers. The total listet for Croats is 1,402 larger than the sum total of the numbers listet for the municipalities. The error does not seem to be in the Sarajevo municipality and its neighbourhoods.
