Everaers was at the helm of the International Monitoring Operation (IMO) in charge of observing the 2013 Population and Housing Census in Bosnia and Herzegovina.
He said that the IMO had concluded that the census had been conducted entirely in line with international standards.
Bosnia and Herzegovina has 3,531,159 inhabitants, Bosniaks are the largest ethnic group (1,769,592 or 50.11%), followed by Serbs (1,086,733 or 30.78%) and Croats (544,780 or 15.43%), according to the first post-war population census whose findings were published in Sarajevo this June.
The census has shown that Bosnia has over 845,000 fewer inhabitants than in 1991 and that the shares of the three constituent peoples in the ethnic make-up have markedly changed. There are 7% more Bosniaks and 2% fewer Croats than before the war, while the share of Serbs is about the same.
However, absolute figures show that there are 130,000 fewer Bosniaks than in 1991, 220,000 fewer Croats and 280,000 fewer Serbs.
The census was conducted in October 2013 but the findings were published only this year because statistical organisations and politicians could not agree on the processing methodology.
The Bosnian Serb authorities declined to accept the published findings.
