Factors Affecting Human Population Density Cities across the globe face large population density, due to enhanced access to civic facilities such as transportation, communication and employment. It is obvious that wherever there are extremes of temperature, human life is difficult to sustain, and consequently such areas are sparsely inhabited. There are two kinds of soil, the superficial matter which covers the solid rock below. Vietnam, since the war, has had an ambivalent attitude towards birth control although a large part of its youthful labor-force had perished during the war. There are, however, marked variations in the Muslim nations of Southeast Asia as well, for example, Indonesia or Malaysia, which have non-Muslim minorities, birth rates tend to be lower. These are diagrams in which the percentage of the population in each age group is shown as a bar male and female population considered separately.
So, the world population density is 13. The developed or industrialized countries which have a high literacy rates show less growth of the population. When a great variety of economic activity is concentrated in a single area, the result is high population density. Natural threats These may affect population density as people may try to avoid areas where pests, threatening animals and diseases are particular risks. The other areas are less dense and are less populated.
They show a direct relationship. Geography therefore, usually considers the main climatic belts of the earth as the framework within which human activity takes place. I do know that the cicadas are commonly found near wood. Nations with stable political and economic scenario tends to remain heavily populated. These industries give rise to towns like Bokaro, Jamshedpur and Bhilai. Population density is usually shown as the number of people per square kilometer.
Such a restriction would prevent couples from being able to have more than the restricted amount of children. Relief and landforms Lowland plains, flat river valleys and deltas and volcanic areas with fertile soil tend to have high population densities. The primary task of a population geographer, therefore, is to explain the irregularities in population distribution in terms of the influences of all these factors as an integral part of a dynamic process Clarke, 1972:14. Besides this, these countries also practice strict immigration procedures. 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. About two-thirds of the immigrants entered Manchuria by sea, and one-third came overland. They would eventually migrate to a more suitable area.
In Egypt, nearly 98 per cent of the population is concentrated forming a ribbon along the Nile River. The most significant internal population movement in modern Chinese history was that of the Han to now known as the Northeast. A more significant measurement that illuminates the relationship between population and development of areas relates people to the cultivated area or growth of capital and industrial production, technology and other economic and social indicators. Better medicine and health car … e. The Sahel Climate Areas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops e. Although reliable population data prior to the 20th century is lacking and even that of the 20th century for most part is scarce, uneven, or misleading , Asia has historically been the home of large populations.
Wherever the terrain is difficult, the area is sparsely populated. The regions inhabited by pastoral nomads also have low density because they migrate with their animals in search of pastures. These are usually places with hostile environments e. The demographic factors consist of natality, mortality, emigration and immigration. Physical environment and weather: fire, flood, temperature etc. The three wealthiest regions are along the southeast coast, centred on the Pearl Zhu River Delta; along the east coast, centred on the lower ; and near the Gulf of Chihli , in the -- region.
About other insects, I'm not quite sure. As for the old-age category, Japan has 15 percent of its population over the age of 60, as compared to only 6. They are also habitats for wild animals which may be a danger to human habitation, Livestock and crops. The population growth rate has increased many folds from the year 1901 to 1981. Weather and climate Temperate areas which experience few extremes of weather and climate tend to be more attracted than areas which experience extremes. This occurs despite the higher literacy rates and economic growth. Anyway, … having a large amount of these type of bushes and not any other necessary supplements for butterflies may cause them to live and breed within only areas with these bushes.
But these numerical comparisons are not strictly valid as Japan is a developed economy, and thus possesses a greater capacity to plan its population. La Paz, the highest city in the world 3,640 m and the capital of Bolivia, owes its existence to this factor. Only Japan, Taiwan and South Korea are the exceptions. Dense forests are sparsely populated. If links between cities and towns are poor, then areas will have a low population density. There are few countries which have maintained their development by immigration.
