 For the 1991 census there were 109 municipalities of which ten were part of Sarajevo.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.
