How many people in the country are called Zhang Qiang?
According to the sixth national census in 20 10, there were1339,724,852 people (excluding Hongkong, Macau and Taiwan Province provinces) in China, which was estimated to be13.4 million, and the underreporting rate was 0. 12%.
Zhang accounts for 7.07% of the country's total population, from which it can be estimated that Zhang's total population is about 95 million. Because it is an estimate, we assume that all the people named Zhang Qiang are male, and the sex ratio of the total population ranges from 105.20 to 100, of which 686,852,572 are male, accounting for 5 1.27%. The female population is 652,872,280, accounting for 48.73%. Then there are about 49 million men surnamed Zhang. Because the general name is related to the education level of parents, with the advancement of basic education, the younger people, the fewer people should take this name. So this is related to the age distribution and the proportion of education in the country.
Of Chinese mainland's 3/kloc-0 provinces, autonomous regions, municipalities directly under the central government and servicemen, the population with college education or above is 1 19636790; The population with high school (including technical secondary school) education is/kloc-0 187985979；; Junior high school education population 519656445; The population with primary school education is 358,764,003 (the above-mentioned population with various education levels includes graduates, dropouts and students of various schools).
Among the 3 1 provinces, autonomous regions, municipalities directly under the Central Government and active servicemen in Chinese mainland, the population aged 0- 14 is 222,459,737, accounting for16.60%; 15-59 years old population is 9396 164 10, accounting for 70.14%; Population aged 60 and above 177648705, accounting for 13.26%, of which population aged 65 and above1/8831709, accounting for 8.87%. Compared with the fifth national census in 2000, the proportion of people aged 0- 14 decreased by 6.29 percentage points, the proportion of people aged 15-59 increased by 3.36 percentage points, the proportion of people aged 60 and over increased by 2.93 percentage points, and the proportion of people aged 65 and over increased by 1.9 1.
Therefore, the school-age male population may have the name of about 39 million. Because of common names (such as Qiang, Wei, Jie, Yong, Lei, Tao, Chao, Gang, etc. ) and the survey among netizens (related renaming network), the ratio is about 1, and the estimation sum error of each link is about 200,000 ~ 300,000 people.
It is purely a personal estimate, and there is no exact basis. I don't take any responsibility related to this, thank you.
