The demographics of the People's Republic of China are identified by a large population with a relatively small youth division, which was partially a result of China's one-child policy. China's population reached the billion mark in 1982.
China's population is 1.411 billion, the largest of any country in the world. According to the 2010 census, 91.51% of the population was Han Chinese, and 8.49% were minorities. China's population growth rate is only 0.59%, ranking 159th in the world. China conducted its sixth national population census on 1 November 2010. Unless otherwise indicated, the statistics on this page pertain to mainland China only; see also Demographics of Hong Kong and Demographics of Macau.
The population of China fluctuated between 30 million and 86 million during the Han dynasty.
After the collapse of the Han Dynasty, the population stayed around 50 million until the advent of the Tang Dynasty.
Under the Tang Dynasty, the population increased from 45 million to 80 million over the course of 200 years.
At the beginning of the Song Dynasty, the population stood at over 100 million.
After Ming and earlier period of Qing dynasty founded population moved around 100 million to 150 million for until 1700s.
In the period between 1749 and 1851, the population doubled in a century.
During 1960-2015, the population doubled to nearly 1.4 billion.
The People's Republic of China conducted censuses in 1953, 1964, 1982, 2000, and 2010. In 1987, the government announced that the fourth national census would take place in 1990 and that there would be one every ten years thereafter. The 1982 census (which reported a total population of 1,008,180,738) is generally accepted as significantly more reliable, accurate, and thorough than the previous two. Various international organizations eagerly assisted the Chinese in conducting the 1982 census, including the United Nations Fund for Population Activities, which donated US$15.6 million for the preparation and execution of the census.
China has been the world's most populous nation for many centuries. When China took its first post-1949 census in 1953, the population stood at 583 million; by the fifth census in 2000, the population had more than doubled, reaching 1.2 billion.
By the sixth census in 2010, the total population had reached to 1,370,536,875, with the mainland having 1,339,724,852, Hong Kong having 7,097,600, and Macau having 552,300.

In 1982 China conducted its first population census since 1964. It was by far the most thorough and accurate census taken since 1949 and confirmed that China was a nation of more than 1 billion people, or about one-fifth of the world's population. The census provided demographers with a set of data on China's age-sex structure, fertility and mortality rates, and population density and distribution. Information was also gathered on minority ethnic groups, urban population, and marital status. For the first time since the People's Republic of China was founded, demographers had reliable information on the size and composition of the Chinese work force. The nation began preparing for the 1982 census in late 1976. Chinese census workers were sent to the United States and Japan to study modern census-taking techniques and automation. Computers were installed in every provincial-level unit except Tibet and were connected to a central processing system in the Beijing headquarters of the State Statistical Bureau. Pretests and small scale trial runs were conducted and checked for accuracy between 1980 and 1981 in twenty-four provincial-level units. Census stations were opened in rural production brigades and urban neighborhoods. Beginning on 1 July 1982, each household sent a representative to a census station to be enumerated. The census required about a month to complete and employed approximately 5 million census takers.
The 1982 census collected data in nineteen demographic categories relating to individuals and households. The thirteen areas concerning individuals were name, relationship to head of household, sex, age, nationality, registration status, educational level, profession, occupation, status of nonworking persons, marital status, number of children born and still living, and number of births in 1981. The six items pertaining to households were type (domestic or collective), serial number, number of persons, number of births in 1981, number of deaths in 1981, and number of registered persons absent for more than one year. Information was gathered in a number of important areas for which previous data were either extremely inaccurate or simply nonexistent, including fertility, marital status, urban population, minority ethnic groups, sex composition, age distribution, and employment and unemployment.
A fundamental anomaly in the 1982 statistics was noted by some Western analysts. They pointed out that although the birth and death rates recorded by the census and those recorded through the household registration system were different, the two systems arrived at similar population totals. The discrepancies in the vital rates were the result of the underreporting of both births and deaths to the authorities under the registration system; families would not report some births because of the one-child policy and would not report some deaths so as to hold on to the rations of the deceased.
Nevertheless, the 1982 census was a watershed for both Chinese and world demographics. After an eighteen-year gap, population specialists were given a wealth of reliable, up-to-date figures on which to reconstruct past demographic patterns, measure current population conditions, and predict future population trends. For example, Chinese and foreign demographers used the 1982 census age-sex structure as the base population for forecasting and making assumptions about future fertility trends. The data on age-specific fertility and mortality rates provided the necessary base-line information for making population projections. The census data also were useful for estimating future manpower potential, consumer needs, and utility, energy, and health-service requirements. The sudden abundance of demographic data helped population specialists immeasurably in their efforts to estimate world population. Previously, there had been no accurate information on these 21% of the Earth's inhabitants. Demographers who had been conducting research on global population without accurate data on the Chinese fifth of the world's population were particularly thankful for the 1982 breakthrough census.
Initially, China's post-1949 leaders were ideologically disposed to view a large population as an asset. But the liabilities of a large, rapidly growing population soon became apparent. For one year, starting in August 1956, vigorous support was given to the Ministry of Public Health's mass birth control efforts. These efforts, however, had little impact on fertility. After the interval of the Great Leap Forward, Chinese leaders again saw rapid population growth as an obstacle to development, and their interest in birth control revived. In the early 1960s, schemes somewhat more muted than during the first campaign, emphasized the virtues of late marriage. Birth control offices were set up in the central government and some provincial-level governments in 1964. The second campaign was particularly successful in the cities, where the birth rate was cut in half during the 1963–66 period. The upheaval of the Cultural Revolution brought the program to a halt, however.
In 1972 and 1973 the party mobilized its resources for a nationwide birth control campaign administered by a group in the State Council. Committees to oversee birth control activities were established at all administrative levels and in various collective enterprises. This extensive and seemingly effective network covered both the rural and the urban population. In urban areas public security headquarters included population control sections. In rural areas the country's "barefoot doctors" distributed information and contraceptives to people's commune members. By 1973 Mao Zedong was personally identified with the family planning movement, signifying a greater leadership commitment to controlled population growth than ever before. Yet until several years after Mao's death in 1976, the leadership was reluctant to put forth directly the rationale that population control was necessary for economic growth and improved living standards.
Population growth targets were set for both administrative units and individual families. In the mid-1970s the maximum recommended family size was two children in cities and three or four in the country. Since 1979 the government has advocated a one-child limit for both rural and urban areas and has generally set a maximum of two children in special circumstances. As of 1986 the policy for minority nationalities was two children per couple, three in special circumstances, and no limit for ethnic groups with very small populations. The overall goal of the one-child policy was to keep the total population within 1.2 billion through the year 2000, on the premise that the Four Modernizations program would be of little value if population growth was not brought under control.
The one-child policy was a highly ambitious population control program. Like previous programs of the 1960s and 1970s, the one-child policy employed a combination of public education, social pressure, and in some cases coercion. The one-child policy was unique, however, in that it linked reproduction with economic cost or benefit.
Under the one-child program, a sophisticated system rewarded those who observed the policy and penalized those who did not. Through this policy, the increasing population got temperate after the penalties were made. Couples with only one child were given a "one-child certificate" entitling them to such benefits as cash bonuses, longer maternity leave, better child care, and preferential housing assignments. In return, they were required to pledge that they would not have more children. In the countryside, there was great pressure to adhere to the one-child limit. Because the rural population accounted for approximately 60% of the total, the effectiveness of the one-child policy in rural areas was considered the key to the success or failure of the program as a whole.
In rural areas the day-to-day work of family planning was done by cadres at the team and brigade levels who were responsible for women's affairs and by health workers. The women's team leader made regular household visits to keep track of the status of each family under her jurisdiction and collected information on which women were using contraceptives, the methods used, and which had become pregnant. She then reported to the brigade women's leader, who documented the information and took it to a monthly meeting of the commune birth-planning committee. According to reports, ceilings or quotas had to be adhered to; to satisfy these cutoffs, unmarried young people were persuaded to postpone marriage, couples without children were advised to "wait their turn," women with unauthorized pregnancies were pressured to have abortions, and those who already had children were urged to use contraception or undergo sterilization. Couples with more than one child were exhorted to be sterilized.
The one-child policy enjoyed much greater success in urban than in rural areas. Even without state intervention, there were compelling reasons for urban couples to limit the family to a single child. Raising a child required a significant portion of family income, and in the cities a child did not become an economic asset until he or she entered the work force at age sixteen. Couples with only one child were given preferential treatment in housing allocation. In addition, because city dwellers who were employed in state enterprises received pensions after retirement, the sex of their first child was less important to them than it was to those in rural areas.
Numerous reports surfaced of coercive measures used to achieve the desired results of the one-child policy. The alleged methods ranged from intense psychological pressure to the use of physical force, including some grisly accounts of forced abortions and infanticide. Chinese officials admitted that isolated, uncondoned abuses of the program occurred and that they condemned such acts, but they insisted that the family planning program was administered on a voluntary basis using persuasion and economic measures only. International reaction to the allegations were mixed. The UN Fund for Population Activities and the International Planned Parenthood Federation were generally supportive of China's family planning program. The United States Agency for International Development, however, withdrew US$10 million from the Fund in March 1985 based on allegations that coercion had been used.
Observers suggested that an accurate assessment of the one-child program would not be possible until all women who came of childbearing age in the early 1980s passed their fertile years. As of 1987 the one-child program had achieved mixed results. In general, it was very successful in almost all urban areas but less successful in rural areas.
Rapid fertility reduction associated with the one-child policy has potentially negative results. For instance, in the future the elderly might not be able to rely on their children to care for them as they have in the past, leaving the state to assume the expense, which could be considerable. Based on United Nations and Chinese government statistics, it was estimated in 1987 that by the year 2000 the population 60 years and older (the retirement age is 60 in urban areas) would number 127 million, or 10.1% of the total population; the projection for 2025 was 234 million elderly, or 16.4%. According to projections based on the 1982 census, if the one-child policy were maintained to the year 2000, 25% of China's population would be age 65 or older by the year 2040. In 2050, the number of people over 60 is expected to increase to 430 million. 
China is the most populated country in the world and its national population density (137/km2) is similar to those of Switzerland and the Czech Republic. The overall population density of China conceals major regional variations, the western and northern part have a few million people, while eastern half has about 1.3 billion. The vast majority of China's population lives near the east in major cities.
In the 11 provinces, special municipalities, and autonomous regions along the southeast coast, population density was 320.6 people per km2.
Broadly speaking, the population was concentrated east of the mountains and south of the northern steppe. The most densely populated areas included the Yangtze River Valley (of which the delta region was the most populous), Sichuan Basin, North China Plain, Pearl River Delta, and the industrial area around the city of Shenyang in the northeast.
Population is most sparse in the mountainous, desert, and grassland regions of the northwest and southwest. In Inner Mongolia Autonomous Region, portions are completely uninhabited, and only a few sections have populations denser than ten people per km2. The Inner Mongolia, Xinjiang, and Tibet autonomous regions and Qinghai and Gansu comprise 55% of the country's land area but in 1985 contained only 5.7% of its population.
Future challenges for China will be the gender disparity. According to the 2010 census, males account for 51.27% of China's 1.34 billion people, while females made up 48.73% of the total. The sex ratio (the number of males for each female in a population) at birth was 118.06 boys to every 100 girls (54.14%) in 2010, higher than the 116.86 (53.89%) of 2000, but 0.53 points lower than the ratio of 118.59 (54.25%) in 2005. In most western countries the sex ratio at birth is around 105 boys to 100 girls (51.22%). At the moment there are about 9 million more boys than girls in China.
China's fertility statistics differ depending on the source. According to the Ministry of Health and Family Planning November 2015 announcement, China's 2015 TFR was somewhere between 1.5 and 1.6. The latest data from the National Bureau of Statistics (NBS) seems to contradict this, stating China's TFR for 2015 was 1,05. Although there is a natural margin of error since the NBS surveys only a thin cross-section of Chinese society, approximately 1% of the total population.
|Average population (x 1000)||Live births1||Deaths1||Natural change1||Crude birth rate (per 1000)||Crude death rate (per 1000)||Natural change (per 1000)||Total Fertility Rate|
|1960||667,070||13,915,000||16,964,000||−3 049 000||20.86||25.43||−4.57|
In 1949 crude death rates were probably higher than 30 per 1,000, and the average life expectancy was only 35 years. Beginning in the early 1950s, mortality steadily declined; it continued to decline through 1978 and remained relatively constant through 1987. One major fluctuation was reported in a computer reconstruction of China's population trends from 1953 to 1987 produced by the United States Bureau of the Census. The computer model showed that the crude death rate increased dramatically during the famine years associated with the Great Leap Forward (1958–60).
According to Chinese government statistics, the crude birth rate followed five distinct patterns from 1949 to 1982. It remained stable from 1949 to 1954, varied widely from 1955 to 1965, experienced fluctuations between 1966 and 1969, dropped sharply in the late 1970s, and increased from 1980 to 1981. Between 1970 and 1980, the crude birth rate dropped from 33.4 per 1,000 to 18.2 per 1,000. The government attributed this dramatic decline in fertility to the wǎn xī shǎo ("晚、稀、少", or "late, long, few": later marriages, longer intervals between births, and fewer children) birth control campaign. However, elements of socioeconomic change, such as increased employment of women in both urban and rural areas and reduced infant mortality (a greater percentage of surviving children would tend to reduce demand for additional children), may have played some role. The birth rate increased in the 1980s to a level over 20 per 1,000, primarily as a result of a marked rise in marriages and first births. The rise was an indication of problems with the one-child policy of 1979. Chinese sources, however, indicate that the birth rate started to decrease again in the 1990s and reached a level of around 12 per 1,000 in recent years.
In urban areas, the housing shortage may have been at least partly responsible for the decreased birth rate. Also, the policy in force during most of the 1960s and the early 1970s of sending large numbers of high school graduates to the countryside deprived cities of a significant proportion of persons of childbearing age and undoubtedly had some effect on birth rates (see Cultural Revolution (1966–76)). Primarily for economic reasons, rural birth rates tended to decline less than urban rates. The right to grow and sell agricultural products for personal profit and the lack of an old-age Welfare system were incentives for rural people to produce many children, especially sons, for help in the fields and for support in old age. Because of these conditions, it is unclear to what degree education had been able to erode traditional values favoring large families.
Today, the population continues to grow. There is also a serious gender imbalance. Census data obtained in 2000 revealed that 119 boys were born for every 100 girls, and among China's "floating population" the ratio was as high as 128:100. These situations led the government in July 2004 to ban selective abortions of female fetuses. It is estimated that this imbalance will rise until 2025–2030 to reach 20% then slowly decrease.
China now has an increasingly aging population; it is projected that 11.8% of the population in 2020 will be 65 years of age and older. Health care has improved dramatically in China since 1949. Major diseases such as cholera, typhoid, and scarlet fever have been brought under control. Life expectancy has more than doubled, and infant mortality has dropped significantly. On the negative side, the incidence of cancer, cerebrovascular disease, and heart disease has increased to the extent that these have become the leading causes of death. Economic reforms initiated in the late 1970s fundamentally altered methods of providing health care; the collective medical care system has been gradually replaced by a more individual-oriented approach.
In Hong Kong, the birth rate of 0.9% is lower than its death rate. Hong Kong's population increases because of immigration from the mainland and a large expatriate population comprising about 4%. Like Hong Kong, Macau also has a low birth rate relying on immigration to maintain its population.
According to the 2000 census, the TFR was 1.22 (0.86 for cities, 1.08 for towns and 1.43 for villages/outposts). Beijing had the lowest TFR at 0.67, while Guizhou had the highest at 2.19. The Xiangyang district of Jiamusi city (Heilongjiang) has a TFR of 0.41, which is the lowest TFR recorded anywhere in the world in recorded history. Other extremely low TFR counties are: 0.43 in the Heping district of Tianjin city (Tianjin), and 0.46 in the Mawei district of Fuzhou city (Fujian). At the other end TFR was 3.96 in Geji County (Tibet), 4.07 in Jiali County (Tibet), and 5.47 in Baqing County (Tibet).
The 2010 census reported a TFR of 1.18 (0.88 in cities, 1.15 in townships, and 1.44 in rural areas). The five regions with the lowest fertility rates were Beijing (0.71), Shanghai (0.74), Liaoning (0.74), Heilongjiang (0.75), and Jilin (0.76). The five regions with the highest fertility rates were Guangxi (1.79), Guizhou (1.75), Xinjiang (1.53), Hainan (1.51), and Anhui (1.48).
In 2012, for the first time, according to statistics released by China's National Bureau of Statistics in January 2013, the number of people theoretically able to enter the Chinese labor force (individuals aged 15 to 59), shrank slightly to 937.27 million people, a decrease of 3.45 million from 2011. This trend, resulting from China's demographic transition, is anticipated to continue for at least the next 20 years, to 2030. The CIA World Fact Book estimates the 2012 actual active labor force to amount to 798.5 million.
As of 2012, the average Chinese man was 167.1 centimeters tall (5 ft 5.8 in) in 2012, the figures showed, and women's average height was 155.8 centimeters (5 ft 1.3 in). The same study showed an average Chinese man weighed 66.2 kilograms (145.9 lbs, or 10 stone 5.9 lbs), up 3.5 kilograms (7.7 lbs) over 10 years, while women were 2.9 kilograms (6.4 pounds) heavier on average at 57.3 kilograms (126.3 pounds, or 9 stone 0.3 lbs). They were up just 0.4 centimeters (0.16 in) and 0.7 centimeters (0.28 in) respectively from 10 years earlier.
The People's Republic of China (PRC) officially recognizes 56 distinct ethnic groups, the largest of which are Han, who constitute 91.51% of the total population in 2010. Ethnic minorities constitute 8.49% or 113.8 million of China's population in 2010. During the past decades ethnic minorities have experienced higher growth rates than the majority Han population, because they are not under the one-child policy. Their proportion of the population in China has grown from 6.1% in 1953, to 8.04% in 1990, 8.41% in 2000, and 8.49% in 2010. Large ethnic minorities (data according to the 2000 census) include the Zhuang (16 million, 1.28%), Manchu (10 million, 0.84%), Uyghur (9 million, 0.78%), Hui (9 million, 0.71%), Miao (8 million, 0.71%), Yi (7 million, 0.61%), Tujia (5.75 million, 0.63%), Mongols (5 million, 0.46%), Tibetan (5 million, 0.43%), Buyi (3 million, 0.23%), and Korean (2 million, 0.15%).

Neither Hong Kong nor Macau recognizes the official ethnic classifications maintained by the central government. In Macau, the largest substantial ethnic groups of non-Chinese descent are the Macanese, of mixed Chinese and Portuguese descent (Eurasians), as well as migrants from the Philippines and Thailand. Overseas Filipinas working as domestic workers comprise the largest non-Han Chinese ethnic group in Hong Kong.
The official spoken standard in the People's Republic of China is Standard Chinese, also known as Putonghua. Its pronunciation is based on the Beijing dialect of the Mandarin Chinese dialect group, which was traditionally the formal version the Chinese language.
Other languages include other varieties of Chinese: Mandarin dialects, as well as Wu (Shanghainese), Yue (Cantonese), Eastern Min (Fuzhou), Southern Min (Hokkien or Taiwanese and Teochiu), Xiang, Gan and Hakka; there are also minority languages spoken in China.
Over 70% of the Han ethnic group are native speakers of the Mandarin group of dialects spoken in northern and southwestern China. The rest, concentrated in south and southeast China, speak one of the six other major Chinese varieties. In addition to their own local dialect, nearly all Chinese also speak Standard Mandarin (Putonghua), which is the language of instruction in all schools and is used for formal and official purposes.
Non-Chinese languages spoken widely by ethnic minorities include Mongolian, Tibetan, Uyghur language and other Turkic languages (in Xinjiang), Korean (in the northeast), and Vietnamese (in the southeast).
In addition to Chinese, in the special administrative regions, English is an official language of Hong Kong and Portuguese is an official language of Macau. Patuá is a Portuguese creole spoken by a small number of Macanese. English, though not official, is widely used in Macau. In both of the special administrative regions, the dominant spoken form of Chinese is Cantonese.
The de facto spoken standard in Hong Kong and Macao is Cantonese, although officially it is just the Chinese language, not specifying which spoken form is standard. The written official standard in Hong Kong and Macao is Mandarin in traditional Chinese characters.
On 1 January 1979, the PRC Government officially adopted the hanyu pinyin system for spelling Chinese names and places in mainland China in Roman letters. A system of romanization invented by the Chinese, pinyin has long been widely used in mainland China on street and commercial signs as well as in elementary Chinese textbooks as an aid in learning Chinese characters. Variations of pinyin also are used as the written forms of several minority languages.
Pinyin replaced other conventional spellings in mainland China's English-language publications. The U.S. Government and United Nations also adopted the pinyin system for all names of people and places in mainland China. For example, the capital of the PRC is spelled "Beijing" rather than "Peking".
China has long been a cradle and host to a variety of the most enduring religio-philosophical traditions of the world. Confucianism and Taoism, plus Buddhism, constitute the "three teachings", philosophical frameworks which historically have had a significant role in shaping Chinese culture. Elements of these three belief systems are often incorporated into the traditional folk religions. Chinese religions are family-oriented and do not demand exclusive adherence, allowing the practice or belief of several at the same time. Some scholars prefer not to use the term "religion" in reference to belief systems in China, and suggest "cultural practices", "thought systems" or "philosophies" as more appropriate terms. There is a stimulating debate over what to call religion and who should be called religious in China. The emperors of China claimed the Mandate of Heaven and participated in Chinese religious practices. Since 1949, China has been governed by the Communist Party of China, which, in theory, is as an officially atheist institution and prohibits party members from belonging to a religion. During Mao Zedong's rule, religious movements were oppressed. Under more recent leaders, religious organisations have been given more autonomy. Presently, the Party formally and institutionally recognises five religions in China: Buddhism, Taoism, Islam, Protestantism, and Catholicism (though despite historic links, the Party enforces a separation of the Chinese Catholic Church from the Roman Catholic Church).
Demographically, the largest group of religious traditions is the Chinese folk religion, which overlaps with Taoism and Confucianism, and describes the worship of the shen 神, a character that signifies the "energies of generation", comprising deities of the natural environment, gods of human groups, heroes and ancestors, and figures from Chinese mythology. Among widespread cults even officially promoted there are those of Mazu (goddess of the seas), Huangdi (divine patriarch of all the Chinese, "Volksgeist" of the Chinese nation), Guandi (god of war and business), Caishen (god of prosperity and richness), Pangu and many others. China has many of the world's tallest statues, including the tallest of all, the Spring Temple Buddha in Henan. Most of them represent buddhas and deities and have been built in the 2000s.
Scholars have noted that in China there is no clear boundary between religions, especially Buddhism, Taoism and local folk religious practice. According to the most recent demographic analyses, an average 80% of the population in China, that is hundreds of millions of people, practice some kinds of Chinese folk religions and Taoism, 10—16% are Buddhists, 2—4% are Christians, and 1—2% are Muslims. In addition to Han people's local religious practices, there are also various ethnic minority groups in China who maintain their traditional autochthone religions. Various sects of indigenous origin gather 2—3% of the population, while Confucianism as a religious self-designation is popular among intellectuals.
Significant faiths specifically connected to certain ethnic groups include Tibetan Buddhism and the Islamic religion of the Hui and Uyghur peoples. Christianity in China was introduced two times between the 7th and the 15th centuries, but failed to take root. It was reintroduced in the 16th century by Jesuit missionaries. Protestant missions and later Catholic missionaries expanded the presence of Christianity, which influenced the Taiping Rebellion of the mid 19th century. Under Communism, foreign missionaries were expelled, most churches closed and their schools, hospitals and orphanages seized. During the Cultural Revolution, many priests were imprisoned. After the late 1970s, religious freedoms for Christians improved.
Internal migration in the People's Republic of China is one of the most extensive in the world according to the International Labour Organization. In fact, research done by Kam Wing Chan of the University of Washington suggests that "In the 30 years since 1979, China's urban population has grown by about 440 million to 622 million in 2009. Of the 440 million increase, about 340 million was attributable to net migration and urban reclassification. Even if only half of that increase was migration, the volume of rural-urban migration in such a short period is likely the largest in human history." Migrants in China are commonly members of a floating population, which refers primarily to migrants in China without local household registration status through the Chinese Hukou system. In general, rural-urban migrant workers are most excluded from local educational resources, citywide social welfare programs and many jobs because of their lack of hukou status.
In 2011 a total of 252.78 million migrant workers (an increase of 4.4% compared to 2010) existed in China. Out of these, migrant workers who left their hometown and worked in other provinces accounted for 158.63 million (an increase of 3.4% compared to 2010) and migrant workers who worked within their home provinces reached 94.15 million (an increase of 5.9% compared to 2010). Estimations are that Chinese cities will face an influx of another 243 million migrants by 2025, taking the urban population up to nearly 1 billion people. This population of migrants would represent "almost 40 percent of the total urban population," a number which is almost three times the current level. While it is often difficult to collect accurate statistical data on migrant floating populations, the number of migrants is undoubtedly quite large. “In China’s largest cities, for instance, it is often quoted that at least one out of every five persons is a migrant.” China's government influences the pattern of urbanization through the Hukou permanent residence registration system, land-sale policies, infrastructure investment and the incentives offered to local government officials. The other factors influencing migration of people from rural provincial areas to large cities are employment, education, business opportunities and higher standard of living.
The mass emigration known as the Chinese diaspora, which occurred from the 19th century to 1949, was mainly caused by wars and starvation in mainland China, invasion from various foreign countries, as well as the problems resulting from political corruption. Most immigrants were illiterate peasants and manual labourers, called "coolies" by analogy to the same pattern of immigration from India, who emigrated to work in countries such as the Americas, Australia, South Africa and Southeast Asia.
Urbanization increased in speed following the initiation of the reform and opening policy. By the end of 2014, 54.7% of the total population lived in urban areas, a rate that rose from 26% in 1990.
