Bosnia and Herzegovina is home to three ethnic "constituent peoples", namely Bosniaks, Serbs, and Croats, plus a number of smaller groups including Jews and Roma.[114] According to data from 2013 census published by the Agency for Statistics of Bosnia and Herzegovina, Bosniaks constitute 50.11% of the population, Serbs 30.78%, Croats 15.43%, and others form 2.73%, with the remaining respondents not declaring their ethnicity or not answering.[115] The census results are contested by the Republika Srpska statistical office and by Bosnian Serb politicians.[116] The dispute over the census concerns the inclusion of non-permanent Bosnian residents in the figures, which Republika Srpska officials oppose.[117] The European Union's statistics office, Eurostat, concluded in May 2016 that the census methodology used by the Bosnian statistical agency is in line with international recommendations.[118]
