China had a 1.30756 billion population by the end of 2005, 7.68 million more than that in the previous year, according to a report released by the National Bureau of Statistics (NBS) on Tuesday.
China has made persistent efforts to slow its population growth over the past 30 years and succeeded in reducing the birthrate.
The birthrate dropped from 21.06 per thousand in 1990 to 12.40 in 2005, while the growth rate went down from 14.39 per thousand to 5.89, according to figures from the NBS.
Although the population growth rate has been reduced, the actual increase is still huge. The country is expecting a peak in the number of elderly and migrant population amid growing imbalance in gender proportions among newborn babies.
China's urban population totaled 562.12 million by the end of 2005, accounting for 43 percent of the total, and rural population reached 745.44 million, accounting for 57 percent.
NBS figures show 673.75 million Chinese are male, making up 51.5 percent, and 633.81 million are female, making up 48.5 percent.
Some 100.55 million Chinese people are over 65 years old, accounting for 7.7 percent of the total.
