(Adjusts figures for number of census workers)
April 28 (Reuters) - China released its 2010 census results on Thursday, the first comprehensive review of the country's demographics in a decade.
Population experts have been warning that China could face potentially disastrous social and economic problems as the population ages and the number of Chinese of working age shrinks.
The following compares some key facts from the 2010 census with results of the 2000 census. (For a full story on the census results, please click on [ID:nL3E7FS08M])
* The 2010 census puts mainland China's (not including Hong Kong and Macau or Taiwan) total population at 1.34 billion, an increase of 5.84 percent from 2000.
* That's a sharply slower rate of growth than the 2000 census showed. China's 2000 census put the country's total population at 1.265 billion, a rise of 11.7 percent over the 1990 figure.
* The annual growth rate was 0.57 percent in the decade to 2010, compared with 1.07 percent in 1991-2000.
* The total population including Hong Kong, Macau and Taiwan in 2010 was 1,370,536,875. The report did not say how census-takers had compiled the data for Taiwan, which is a self-ruled island over which Beijing claims control.
* The government says 10 million workers were involved in conducting the census -- a figure similar to the previous census in 2000. Earlier reports had said the number of census workers this time was 6 million but it is not clear which categories of workers are covered by the different figures.
* In 2010, 16.60 percent of the population was 14 or younger, a sharp decline from 22.89 percent in 2000.
* The old-age population continued to increase as a proportion of the whole, with citizens aged 60 or more accounting for 13.26 percent, 2.93 percentage points higher than in 2000.
* In 2010, 8.87 percent were 65 or older, compared with 6.96 percent in 2000 and 5.57 percent in 1990. FLOATING POPULATION
* The 2010 census marks the first time China counted migrant workers based on where they lived and worked, not the location of their national household registration, or hukou.
* In 2010, 221.4 million people had left the locality of their registered address for more than six months. That represented a rise of 100.36 million -- or 82.89 percent -- over the 2000 figure.
* Calculating China's "floating population" hampered census workers in 2000, but experts estimated that the country had about 200 million migrant workers at the time.
* China had 105.20 males for every 100 females, with females accounting for 48.73 percent of the total.
* In 2000, China had 106.74 males to every 100 females. Experts said this disparity was due to China's family planning policies, which encouraged under-reporting of female births and the practice of self-selective abortion after the sex of a child was determined using an ultrasound.
* Nearly half of the population -- 49.7 percent live in urban areas, showing a rapidly urbanising China.
* In 2000, 36.09 percent of Chinese lived in cities, an increase of 9.86 percent points over the figure from the 1990 census. That figure used a different counting method than the 2010 census, however, which counts migrant workers living in cities.
* The 2010 census showed the population of the eastern region grew to 37.98 percent from 35.57 percent in 2000. The other regions -- central, western and northeastern China -- all saw their populations decline as a percentage of China's total population.
* Since 2000, the decline in western China was the fastest, falling 1.11 percentage points.
* No information was given about which provinces were included in which regions.
* The top five provinces remained the same, but Guangdong jumped into first place, leap-frogging Shandong and Henan, which were the second and first most populous in 2010.
* No data has been provided yet for the fertility rate in 2010.
* China's fertility rate, which stood at four births per mother in 1970, was 1.82 in 2000.
* China's 55 registered ethnic groups, aside from the majority Han Chinese, accounted for 8.49 percent of the population, up from 8.41 percent in 2000.
* The average annual growth of the minority population was 0.67 percent, compared with 0.11 percent in the Han majority. ILLITERACY AND EDUCATION
* In 2010, the number of people with a university education was 8,930 per 100,000, almost 2.5 times more than in 2000, when it stood at 3,611.
* In 2010, the illiteracy rate of people 15 years of age or older was 4.08 percent.
* China's illiteracy rate was 6.72 percent in 2000, and 15.88 percent in 1990. (Reporting by Michael Martina, Wang Lan, Tom Miles and Don Durfee; Editing by Ken Wills and Ron Popeski)
