Population density and distribution

Population density describes the number of people living in a given area. It is calculated as follows:

Population density varies strikingly, with the greatest contrast occurring between the eastern half of China and the lands of the west and the northwest. Most of Population density and distribution high-density areas are coterminous with the alluvial plains on which intensive agriculture is centred.

In contrast, the isolated, extensive western and frontier regions, which are Population density and distribution larger than any European country, are sparsely populated. Extensive uninhabited areas include the extremely high northern part of Tibetthe sandy wastes of the central Tarim and eastern Junggar basins in Xinjiangand the barren desert and mountains east of Lop Nur.

In the s the government became increasingly aware of the importance of the frontier regions and initiated a drive for former members of the military and young intellectuals to settle there. New railways and highways were constructed to traverse the wasteland, and this has spurred population growth and the development of a number of small mining and industrial towns.

Internal migration Great population movements have been a recurring theme throughout Chinese history. Typically, some disastrous event such as famine or political upheaval would depopulate an area already intensively cultivatedafter which people in adjacent crowded regions would move in to occupy the deserted land.

A peasant rebellion in Sichuan in the s caused great loss of life there, and people from neighbouring Hubei and Shaanxi then entered Sichuan to fill the vacuum; this migration pattern continued until the 19th century. Three centuries later the Taiping Rebellion caused another large-scale disruption of population.

Many people in the lower Yangtze valley were massacred by the opposing armies, and the survivors suffered from starvation. After the rebellion was defeated, people from HubeiHunanand Henan moved into the depopulated areas of JiangsuAnhuiand Zhejiangwhere farmland was lying abandoned and uncultivated.

The most significant internal population movement in modern Chinese history was that of the Han to Manchuria now known as the Northeast.

Even before the Qing Manchu dynasty was established inManchu soldiers had launched raids into North China and captured Han labourers, who were then obliged to settle in Manchuria. An imperial decree in closed the area to further Han migration, but this ban was never effectively enforced.

ByHan colonizing settlers had become dominant in Manchuria. The ban was later partially lifted, partly because the Manchu rulers were harassed by disturbances in China proper and partly because the Russian Empire continually tried to invade sparsely populated and thus weakly defended Manchuria.

The ban was finally removed altogether inbut settlement was encouraged only after The influx of people into Manchuria was especially pronounced afterand incoming farmers rapidly brought a vast area of virgin grassland under cultivation.

About two-thirds of the immigrants entered Manchuria by sea, and one-third came overland. After the autumn harvest a large proportion of the farmers returned south. As Manchuria developed into the principal industrial region of China, however, large urban centres arose there, and the nature of the migration changed.

No longer was the movement primarily one of agricultural resettlement, and instead it became essentially a rural-to-urban movement of interregional magnitude. Although the total number of people involved in such migrations is not known, it has been estimated that by between one-fourth and one-third of the population of such regions and provinces as Inner MongoliaXinjiang, Heilongjiangand Qinghai consisted of recent migrants, and migration had raised the proportion of Han in Xinjiang to about two-fifths of the total.

Efforts to control the growth of large cities led to the resettlement in the countryside of some 20 million urbanites after the failure of the Great Leap Forward and of nearly the same number of urban-educated youths in the decade after The economic reforms begun in the late s have unleashed a tidal wave of both rural-to-urban and west-to-east migration, reversing trends of the previous three decades.

However, tens of millions of rural people who go to the cities to find jobs also return home for periods of time during the year.

These individuals have tended to group themselves according to their native area for mutual benefit, much as ethnic groups have done in other major world cities.

However, the unregulated influx of so many migrants and the instability of their lives and work have put considerable strain on the host cities, notably the environment and public security. However, since the late s China has dramatically increased its interaction with the international economy, and it has become a dominant figure in world trade.

The Chinese economy thus has been in a state of transition since the late s as the country has moved away from a Soviet-type economic system. Agriculture has been decollectivized, the nonagricultural private sector has grown rapidly, and government priorities have shifted toward light and high-technology, rather than heavy, industries.

Nevertheless, key bottlenecks have continued to constrain growth. The three wealthiest regions are along the southeast coast, centred on the Pearl Zhu River Delta; along the east coast, centred on the lower Yangtze River ; and near the Bo Hai Gulf of Chihliin the Beijing - Tianjin - Liaoning region.

It is the rapid development of these areas that is having the most significant effect on the Asian regional economy as a whole, and Chinese government policy is designed to remove the obstacles to accelerated growth in these wealthier regions.

At the same time, a major priority of the government is the economic development of the interior of the country to help it catch up with the more-prosperous coastal regions. Its mineral resources are probably among the richest in the world but are only partially developed.

China has acquired some highly sophisticated production facilities through foreign investment and joint ventures with foreign partners."What is the Difference Between Population Density and Population Distribution?"
