China's population grew to 1.34 billion people last year, the National Bureau of Statistics announced Monday, AP reported. The figure of 1.3410 billion, which is preliminary and based on a sample survey, shows China added about 6.3 million people last year, up from 1.3347 billion at the end of 2009. A more accurate figure is expected to be released within the next few months, after the government tallies the results of its 2010 census, the first in 10 years.
