The lowest figure in the Asia-Pacific region is that of North and Central Asia, a sub region where the population growth rate dropped to an average of -0.1% between 1990 and 2000, but subsequently rose to 0.3% in 2010.Differences in population growth rates by country are greater than by sub region level. Four countries experienced a negative annual average population growth between 2005 and 2010: Georgia, Niue, Northern Mariana Islands and the Russian Federation.
The population growth trends are largely a consequence of declining birth rates across the region. Countries with the most rapid declines in the crude birth rate (CBR) include Bhutan, Cambodia, the Lao People’s Democratic Republic, Maldives, and Singapore with declines exceeding 40% from the 1990-1995 average to 2010
