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. According to data from the 2013 census published by the Agency for Statistics of Bosnia and Herzegovina, Bosniaks constitute 50.1% of the population, Serbs 30.8%, Croats 15.5% and others 2.7%, with the remaining respondents not declaring their ethnicity or not answering. The census results are contested by the Republika Srpska statistical office and by Bosnian Serb politicians. The dispute over the census concerns the inclusion of non-permanent Bosnian residents in the figures, which Republika Srpska officials oppose. 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.
