Ma Jiantang, deputy head of the Sixth National Census Leading Group of the State Council and director of the National Bureau of Statistics, released the main data bulletin of the Sixth National Census in 2010 (No. 1). The main data of the Sixth National Census was released at 0:00 on November 1, 2010. Under the correct leadership of the Party Central Committee and the State Council, and with the strong support of the central departments and local people at all levels, with the active cooperation of the national news media, and with the hard work of nearly 10 million census personnel and the active participation of 1.3 billion people of all ethnic groups, the census successfully completed on-site registration, review and post-event quality random inspections. The main data quickly summarized will now be announced. 1. Total population The total population of the country registered in this census is 1339724852. Compared with the fifth national census in 2000, there has been an increase of 73.9 million in ten years, an increase of 5.84%, and an average annual growth rate of 0.57%, which is 0.5 percentage points lower than the average annual growth rate of 1.07% from 1990 to 2000. Data shows that my country's population growth has been at a low fertility level in the past ten years. 2. Household Size In this census, there were 401.52 million household households in 31 provinces, autonomous regions, and municipalities directly under the Central Government, with a household population of 1,244.61 million. The average population per household was 3.10, which was 0.34 less than the 3.44 in the 2000 census. The size of households continues to shrink, mainly due to factors such as the continuous decline in my country's fertility level, the increase in migrant migrant population, and young people living independently after marriage. 3. Gender Composition In this census, the male population accounted for 51.27% and the female population accounted for 48.73%. The sex ratio of the total population dropped from 106.74 in the 2000 census to 105.20(the female population was 100.00). 4. Age Composition In this census, the population aged 0-14 accounted for 16.60%, a decrease of 6.29 percentage points from the 2000 census; The population aged 60 and above accounted for 13.26%, an increase of 2.93 percentage points from the 2000 census, of which the population aged 65 and above accounted for 8.87%, an increase of 1.91 percentage points from the 2000 census. The changes in the age structure of my country's population show that with the rapid development of my country's economy and society, the tremendous improvement of people's living standards and medical and health care undertakings, the fertility rate continues to remain at a low level, and the aging process is gradually accelerating. 5. Ethnic composition In this census, the Han population accounted for 91.51%, a decrease of 0.08 percentage points from the 91.59% in the 2000 census; The ethnic minority population accounted for 8.49%, an increase of 0.08 percentage points from 8.41% in the 2000 census. The ethnic minority population has grown at an average annual rate of 0.67% in ten years, which is 0.11 percentage points higher than that of the Han nationality. 6. Population with various educational levels In this census, compared with the 2000 census, the number of people with a college education per 100,000 people has increased from 3611 to 8930, and the number of people with a high school education has increased from 11146 to 14032; The number of people with a junior high school education has increased from 33961 to 38788; The number of people with primary school education dropped from 35701 to 26779. The illiteracy rate (the proportion of illiterate people aged 15 and above to the total population) was 4.08%, a decrease of 2.64 percentage points from 6.72% in the 2000 census. Changes in the population with various educational levels and illiteracy rates reflect the positive results achieved in my country's measures to popularize nine-year compulsory education, vigorously develop higher education, and eliminate illiteracy among young and middle-aged people over the past ten years. 7. Composition of Urban and Rural Areas In this census, the population living in cities and towns was 665.57 million, accounting for 49.68% of the total population, and the population living in rural areas was 674.15 million, accounting for 50.32%. Compared with the 2000 census, the proportion of urban population increased by 13.46 percentage points. This shows that my country's rapid economic and social development since 2000 has greatly promoted the improvement of urbanization level. 8. Regional distribution In this census, the population of the eastern region accounted for 37.98% of the permanent population of 31 provinces (autonomous regions and municipalities), the central region accounted for 26.76%, the western region accounted for 27.04%, and the northeastern region accounted for 8.22%. Compared with the 2000 census, the proportion of the population in the eastern region increased by 2.41 percentage points, while the proportion of the central, western and northeastern regions all declined. Among them, the western region experienced the largest decline, with a decrease of 1.11 percentage points; followed by the central region, with a decrease of 1.08 percentage points; the northeastern region dropped 0.22 percentage points. According to permanent population, the top five are Guangdong Province, Shandong Province, Henan Province, Sichuan Province and Jiangsu Province. The top five in the 2000 census were Henan Province, Shandong Province, Guangdong Province, Sichuan Province, and Jiangsu Province. 9. Population mobility In this census, the number of people whose place of residence is inconsistent with the township streets where their household registration is located and who have left their household registration for more than half a year is 261.39 million. Among them, 39.96 million people were separated from households in municipal areas, excluding 221.43 million people. Compared with the 2000 census, the population whose place of residence is inconsistent with the township streets where the household registration is located and who have left the household registration place for more than half a year increased by 117 million, an increase of 81.03%; excluding the population with separated households within municipal districts, the population increased by 100.36 million, an increase of 82.89%. This is mainly due to the accelerated transfer of rural labor and rapid economic development in my country over the years, which have promoted a large increase in the floating population. After the on-site registration of the census was completed, 402 census communities across the country were randomly selected for post-quality spot checks. Compared with the on-site registration results, the missed registration rate of this census was 0.12%. This census has obtained a large amount of basic data on my country's total population, quality, structure, and distribution. It is an extremely valuable information wealth and has important reference value for formulating economic and social development policies during the "Twelfth Five-Year Plan" period. We are organizing efforts to conduct detailed summary and analysis, and will announce them one after another.
