Following an incomplete count due to ethnic conflicts in parts of the country, Myanmar said on Saturday that its first census in 30 years shows the population to be 51.4 million, some 10 million less than expected.

The provisional findings of the census, taken between March and April with support from the U.N. Population Fund (UNFPA), was released by Minister of Immigration and Population U Khin Yi.

The census was mired in controversy from the outset, as the government and UNFPA were criticized for basing the counting on 135 officially recognised ethnic groups, a classification that critics say is outdated and inaccurate.
