2000 Chinese census
The 2000 Chinese census, officially the Fifth National Population Census of the People's Republic of China (), was conducted by the government of the People's Republic of China with 1 November 2000 as its zero hour. The total population was calculated as 1,295,330,000. The census also covered population growth, number of households, sex, age, ethnicity, educational attainment, and urban and rural population. The census did not include the special administrative regions of Hong Kong and Macau. Population by province-level division. Based on the results of the Fifth National Population Census, Henan was the most populous  province-level division, Shandong was ranked second, Guangdong and Sichuan were third and fourth, and Jiangsu, Hebei, Hunan, Hubei, Anhui, and Zhejiang were ranked fifth through tenth. Hainan, Ningxia, Qinghai, and Tibet were the four least populous, with fewer than 10 million people each. Tibet was the least populous of all, with 2,620,000 people. There were nine province-level divisions with more than 50 million people, eighteen with 10–50 million people, and four with less than 10 million people. Distribution of ethnic minorities. There were four province-level divisions with an ethnic minority population of more than 10 million: in  decreasing order, Guangxi, Yunnan, Guizhou, and Xinjiang. There were two more provinces, Liaoning and Hunan, with an ethnic minority population of more than 5 million. Fourteen more, including Inner Mongolia and Sichuan, had an ethnic minority population of more than 1 million. Three more (Shandong, Beijing, and Fujian) had more than 500,000, while the remaining eight had more than 100,000 each. There were 13 province-level divisions where the proportion of ethnic minorities was higher than the national average. In Tibet and Xinjiang more than 50% of the population belonged to ethnic minorities: 93.94% in Tibet and 59.43% in Xinjiang . In Qinghai, Guangxi, Guizhou, Ningxia, and Yunnan the ethnic minority population was greater than 30%. In Inner Mongolia it was 20.83%. In Hainan, Liaoning, and Hunan it was more than 10%, and in Jilin and Gansu it was also greater than the nationwide proportion of 8.41%. Ethnicity. The Han Chinese population had increased by 11.22% since the 1990 census, going from 91.96% of the population to 91.59%. The ethnic minority population had increased by 16.70% since the 1990 census, going from 8.04% of the population to 8.41%. The ethnic minority population grew at a higher rate than the Han population  due to affirmative action under the one-child policy. After Han, the second most populous ethnic group was the Zhuang, followed by the Manchus, each of which had more than 10 million people, and the Hui with 9,817,000 people. There were more than 8 million Miao, Uyghurs, and Tujia; 7,762,000 Yi; more than 5 million Mongols and Tibetans; more than 1 million but less than 3 million of each of nine ethnic groups including the Buyi, Dong, Koreans, and Kazakhs; more than 100,000 but less than 1 million of each of 17 ethnic groups including the She, Lisu, and Kyrgyz ; and more than 10,000 but less than 100,000 of each of 13 ethnic groups including the Blang and Tajiks. Seven other ethnic groups, including the Moinba, Oroqen, and Drung, had a population of less than 10,000 each; among them, the Tatars, Hezhe, indigenous Taiwanese, and Lhoba had less than 50,000 each. The least populous ethnic group was the Lhoba, with only 2,965 people. There were 734,438 people belonging to unrecognized ethnic groups, including 710,486 in Guizhou (96.74% of the total), 7,404 in Yunnan (1.01%), and more than 1,000 in each of Tibet, Zhejiang, Guangdong, Guangxi, and Jiangsu. Key indices. Population  growth. The population had increased by 132,150,000 (11.66%) over the population of 1,133,680,000 from the Fourth National Census on 1 July 1990. The average rate of population growth per year was 1.07%. Households. There were 348,370,000 households, with 1,198,390,000 people. The average household size was 3.44 people, a decrease of 0.52 from the 1990 average household size of 3.96. Sex. There were 653,550,000 males (51.63% of the population) and 612,280,000 females (48.37%). The sex ratio was 106.74 men for every 100 women. Age. There were 289,790,000 children aged 0-14, representing 22.89% of the population; 887,930,000 people aged 15–64, representing  70.15% of the population; and 88,110,000 people aged 65 and older, representing 6.96% of the population. The proportion of people 14 and under had decreased by 4.8% since the 1990 census, and the proportion of people 65 and over had increased by 1.39%. Educational attainment. Among the population, 45,710,000 people had attended higher education; 141,090,000 people had attended high school (including vocational high school); 429,890,000 had attended middle school; and 451,910,000 had attended elementary school. (These figures include people who completed the level of education indicated, people who failed to complete it, and current students.) In comparison with the 1990  census, the following changes happened (per 100,000 people): The illiteracy rate (people age 15 and above who are unable to read or can only read very little) was 85,070,000 people. The illiteracy rate had decreased from 15.88% in 1990 to 6.72% in 2000, a decrease of 9.16 percentage points. Urban and rural population. The urban population was 455,940,000 (36.09%), and the rural population was 807,390,000 (63.91%). The urban population had increased by 9.86% since 1990. Analysis. The 2000 census counted people according to their "hukou" rather than their location of actual residence. Experts believe that it may have underestimated the  proportion of the population living in urban areas.
