Effect of geography on population distribution

Population pyramids for every country in the world can be found here. Growing commercial activities, for instance, in the developing world, accompanied by improvements in transport network, have resulted in considerable redistribution of population and emergence of mega urban centres.

As a general rule the higher the life expectancy the more healthy or developed a country is. In the world's population reached 1 billion. With increasing state control over economic activities, government policies have led to a significant change in the patterns of population distribution in several parts of the world.

The prices of some key commodities, especially of industrial raw materials and major industrial products, are still determined by the state, although the proportion of these commodities under state control continues to decline.

Population Distribution, Settlement Patterns and Accessibility across Africa in 2010

The industrial revolution has resulted in considerable change in population distribution in many parts of the world. Population pyramids are used to show the structure of the population according to age and sex. Although climatic optima are difficult to define, extremes of temperature, rainfall and humidity certainly limit the concentration of population in any part of the earth.

The labour force and the pricing system are still areas of concern. There are several instances of formerly prosperous and densely populated areas, which are now only sparsely populated.

Integrated geography Environmental geography is concerned with the description of the spatial interactions between humans and the natural world. The technological level and quality standards of many of its industries have improved rapidly and dramatically.

These early foundations of population geography were quite different from and indeed had relatively little effect on demography, but from the s it was increasingly argued that geographers needed to focus more clearly on demographic methods. Each stage in economic development was marked with profound changes in population density and distribution in the region.

Antarctica or far too hot e. Underemployment is common in both urban and rural areas, and there is a strong fear of the disruptive effects that widespread unemployment could cause. Some population geographers called for a greater awareness of social theory in population geography, for a more critical view of established data sources and theories, and for a move to qualitative as well as quantitative methods.

Death rates are number of people dying per people. A concern with spatial variation has been the geographer's distinctive contribution to population studies, in comparison to the demographer, who is much more interested in patterns of birth, marriage, and death, and less interested in the influence of migration and spatial variations in general.

Bring fact-checked results to the top of your browser search. This is particularly true in the temperate and other high latitude areas where insolation is very important. This information is displayed as an age-sex or population pyramid.

Social Groups of people want to live close to each other for security e. The main aim is to understand, or define the uniqueness, or character of a particular region that consists of natural as well as human elements.

GEOGRAPHY, POPULATION

Some of the geographers in past have, therefore, gone to the extent of claiming a deterministic relationship between climate and population distribution. Each stage in economic development was marked with profound changes in population density and distribution in the region.

For Trewartha, "population is the point of reference from which all other elements are observed and from which they all, singly and collectively, derive significance and meaning. 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.

Post-partition redistribution between India and Pakistan, or displacement of several million Sudanese as a result of civil war, or expulsion of Asians from Uganda in the early s are some of the instances of how political events can cause changes in population patterns.

Most of the high-density areas are coterminous with the alluvial plains on which intensive agriculture is centred. Regional science comprises the body of knowledge in which the spatial dimension plays a fundamental role, such as regional economicsresource managementlocation theoryurban and regional planningtransport and communicationhuman geographypopulation distribution, landscape ecologyand environmental quality.

Improved transport network, growing spatial mobility of labour and increasing trade in the wake of economic and technological advancements have led to decline in the importance of place bound industries.

In association with climatic conditions, varying soil types give rise to variety of vegetation cover on the earth surface. They must learn geodesy and fairly advanced mathematics to understand how the shape of the Earth affects the distortion of map symbols projected onto a flat surface for viewing.

As against this, in the high latitude areas, it becomes extremely difficult to live beyond a few hundred metres from sea level. No longer was the movement primarily one of agricultural resettlement, and instead it became essentially a rural-to-urban movement of interregional magnitude.

Demographers such as Ansley J. Likewise, sun-facing slopes provide favourable locations for the emergence and growth of settlements.Population distribution.

Factors that Affects Population Distribution

China’s complex natural conditions have produced an unevenly distributed population. Population density varies strikingly, with the greatest contrast occurring between the eastern half of China and the lands of the west and the northwest.

It is, however, not to suggest that population distribution on the earth surface is determined by physical factors alone, for within the broad framework of physical attractions and constraints, cultural factors strongly influence the way mankind is distributed over the earth (Hornby and Jones, ).

Population geography is a division of human geography. It is the study of the ways in which spatial variations in the distribution, composition, migration, and growth of populations are related to the nature of places.

Population geography involves demography in a geographical perspective. Population geography is a branch of human geography that is focused on the scientific study of people, their spatial distributions and density.

To study these factors, population geographers examine the increase and decrease in population, peoples' movements over time, general settlement patterns. Geographers study the space and the temporal database distribution of phenomena, of cause and effect.

regional economics, resource management, location theory, urban and regional planning, transport and communication, human geography, population distribution, landscape ecology, and environmental quality. The Effects of Population on the Environment chapter of this Human Geography Help and Review course is the simplest way to master the effects of population on the environment.
