What factors affect population density and distribution?

Character and causes of population distribution in Shenyang city, China

Combining GIS measures and statistic methods, this paper selects the physiographic factors and climatic factors to study the influencing strength and its functional forms of all factors on population density in the LRGR.

Describe and explain the physical and human factors affecting population distribution at the global scale. What might be the physical natural and human reasons for this? The pattern of where people live. World population distribution is uneven.

Factors influencing global population distribution Physical factors Climate People prefer to live in temperate climates where there is enough rainfall and no extremes of temperature. A lack of fresh water for drinking or irrigation stops people living in an area. Very high temperatures make farming difficult. Dehydration and heat stroke are other issues. Areas with high humidity are also uncomfortable places to live and can be affected by diseases such as malaria. Very cold temperatures make it difficult to grow crops or to build homes and transport links as the ground can be frozen for much of the year. Frostbite makes it difficult to work outside for any length of time, and protective clothing would need to be worn.

Multiple stepwise regression is carried out to identify the influencing factors of population dynamics in border regions. Given the increasingly market-oriented migration mechanism, the national reclamation policy has been no longer effective in population attraction in the new century. Education has significantly lowered and will continuously lower the fertility rate in remote border areas.

Character of population distribution is one of the focuses studied by urban geography. Using the fifth national census data as basic data and using areal interpolation method, this paper analyzes character of urban population distribution of Shenyang City, Northeast China, in terms of three aspects of statistical character, spatial auto-correlation and spatial structure. Furthermore, this research analyzes the factors affecting the population distribution of the city. The main conclusions include: 1 There is an obvious structure character of population distribution in the grid with a grain of m, which is appropriate scale when researching population distribution in Shenyang City. Spatial heterogeneity of population density is low. Population density distribution has multi-cores character.

What factors affect population density and distribution?

Population distribution is a term used to describe how humans are spread across the Earth. Population distribution across the Earth is uneven. Some areas are densely populated, whereas others are sparsely populated. Areas with extreme climates such as hot and cold deserts make it difficult to grow crops and access water.

Birth rates can be lowered by any one of a variety of practices: by late marriage and not marrying, as in Ireland; by induced abortion, as in Japan and the eastern European countries; or by contraception, as in all the western countries. An increase of five years in age of marriage in India would result in a decline of about 20 per cent in the birth rate; a decrease of 15 per cent in the proportion of people married would result in a corresponding decrease in the birth rate. But the marriage practices of a society are closely bound up with its social and cultural institutions and hence are not easily or quickly changed. Such shifts probably have to come as part of those long-term and basic changes in the very fabric of a society that accompany the transition from traditional to modern status. Induced abortion is widely and legally practiced in some countries, and it is quite widely but illegally, and badly, practiced in many others.

    The main factors determining population distribution are: climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbours, navigable rivers or canals, cultural factors, political boundaries, controls on migration and trade, government policies, types of.
