Thus, using the annual increase rate of 2--3%, the most population estimates were around 2 million in the year 2000 . A national census was carried out in 2005 and it turned out that the population was 672,425 . Consequently, United Nations Population Division reduced its estimation of the country's population in the 2006 revision for the whole period from 1950 to 2050 . </Li> </Ol> </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Kingdom of Bhutan འབྲུག ་ རྒྱལ ་ ཁབ ་ (Dzongkha) Druk Gyal Khap </Th> </Tr>
