factors affecting population distribution

In Egypt, nearly 98 per cent of the population is concentrated forming a ribbon along the Nile River. Kalgoorlie, a gold mining town in the Australian deserts, is a very good example in this regard. Industrialization and discovery of new sources of minerals and energy resources have, throughout human history, brought about redistribution of population through migration. The social and economic factors affecting population distribution are: (1) the type of economic activity; (2) the type of technology employed; and (3) social policy. For example, in some islands, most people live near the coast and few live in the interior. Factors affecting Distribution of Population 1.1 Introduction Population distribution is the spatial pattern of the dispersal of populations, formation of agglomerations, linear spreads of population, etc. ← Prev Question Next Question → 0 votes . Physical factors that affect population distribution include altitude and latitude, relief, climate, soils, vegetation, water and location of mineral and energy resources. Species distribution is the manner in which a biological taxon is spatially arranged. These, in turn, provide contrasting environment for a variety of agricultural activities, and hence, lead to different population density. Physical factors include shape and height of the land, resources, and climate. Cultural Factors 4. Areas in which populations are small usually lack one of these four qualities. Nearness to sea, lack of roads, temperate climate, lack of industries, new cities and towns, tropical moist forests, minerals, semi-arid climate, cultivable land. African tribesmen, who lived in their own self-sufficient economies, initially had no incentive to work on wages for European enterprises. Job opportunities attract people to live there as more jobs = more income = more infrastructure and transport. Lowland plains, flat river valleys and deltas and volcanic areas with fertile soil tend to have high population densities. It is only in some exceptional areas like those with extremely cold climate that the factor of climate itself determines population growth. Coastal plains and interior plateaus where crops grow well, animals can be reared and raw materials for industries can be found tend to have high population densities Transport networks are easy to build due to gentle and undulating landscape Areas that experience extremely low or high temperatures tend to be sparsely populated The influence of altitude has already been noted. The social and economic factors affecting population distribution are: (1) the type of economic activity; (2) the type of technology employed; and (3) social policy. The main reason for this is the fact that, as man gains increasing control over natural phenomena, he is less inclined to accept the natural conditions in which he finds himself, but tends to modify these to suit his own requirements, if other conditions of habitation social and economic conditions are attractive. Same geographic conditions provide different opportunities for people with different types and scale of economic activities. There are now more than 28,000 cities with more than 5000 inhabitants and about 1000 with more than 100000 inhabitants. Declining birth and death rates are the major reasons why Japan is … Global factors affecting business The way of running the business differs from country to country. Over the past couple of decades Japan has experienced a significant decrease in the population. 1800 years ago there were 750 cities with more than 5000 inhabitants and 45 with more than 100000 inhabitants. On the other hand, in urban areas, people do not depend on land for sustenance and, therefore, can live in one area, though they depend on products from other areas. An approximate estimate has been made of the proportion of the world’s soil that is fit for cultivation in the present times. The major soil factors which influence the microbial population, distribution and their activity in … PreserveArticles.com is a free service that lets you to preserve your original articles for eternity. SocialAreas will have a high population density if they are located close to good communications links. Classify the factors affecting the distribution of population into favourable and unfavourable. All these factors are usually inter-related. 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. Geographical Factors 2. Mountains in Africa and Latin America are much healthier than plains, and large cities have sprung up at high altitude. Normally speaking, plain areas encourage higher density of population as compared to mountain regions. It the past, because of lack of such knowledge, degradation of the sort has been known to be the cause of the disappearance of flourish” civilisations like that of the Mayas in Central America. Geographical Factors 2. The mining areas, therefore, lacked a sufficient labour force, and most of the workers had to come from other areas, either of the same country or from adjoining countries, and sometimes even from distant countries. Institute of Terrestrial Ecology, Banchory, Scotland. Social and Economic Factors of Population Distribution. Population distribution (how people are geographically spread out) within countries is also varied. Among the many kinds of minerals, coal was the first to be used as a source of both heat and motive power, and soon became a symbol of man’s control over nature. Answer the question as per the instructions. Plagiarism Prevention 4. Sites of water power are also able to attract population, though not to the same extent as minerals, because electricity can be transmittal over long distances, and industries do not have to be set up at the place where electricity is generated. Declining birth and death rates are the major reasons why Japan is … Population Distribution Population distribution means the pattern of where people live. Migration has positive and negative effects on a country or area. The concentration of communities has accelerated the growth of populations. Thus, apart from physical factors, numerous social, demographic, economic, political and historical factors affect population distribution. It is the average number of the children born in a country compared to the rest of the population. There are many factors contributing to the unbalanced population distribution, including natural condition, social and economic development, and transportation infrastructure. What are the Factors affecting the distribution of insolation? As against this, in the high latitude areas, it becomes extremely difficult to live beyond a few hundred metres from sea level. In countries such as Dominica and Guyana, forests, rugged terrain and rivers deter settlements in vast areas of the country, forcing people to occupy a relatively small geographic area of their total land space. Factors affecting population growth. Lesson 10 of 10 • 1536 upvotes • 12:33 mins. There are many factors that contribute to population density and distribution. In association with climatic conditions, varying soil types give rise to variety of vegetation cover on the earth surface. Each stage in economic development was marked with profound changes in population density and distribution in the region. Though the three demography variables fertility, mortality and migration are themselves determined by social, economic and geographic factors, it is possible to consider them in the light of their influence on population distribution. Several factors determine an area's population distribution and density. It is obvious that wherever there are extremes of temperature, human life is difficult to sustain, and consequently such areas are sparsely inhabited. For instance, in a mountainous region, population density is low because the area of arable land is limited, and it is difficult to maintain even the existing arable land. As against this, in tropical swamps and dissected plateaus, river valleys tend to repel population. Search for more papers by this author. 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, 1980:20). 10 views. Large towns have grown up in inaccessible and extremely inhospitable areas such as deserts, Polar Regions or in the midst of forests where precious minerals and metals have been found. La Paz, the highest city in the world (3,640 m) and the capital of Bolivia, owes its existence to this factor. 9:54 mins. Wars have forced a great number of people to migrate from one region to another all over the world. Natality 2.Mortality 3.Dispersal 4.Age Distribution 5.Biotic Potential and Environmental Resistance 6.Biotic and Abiotic Factors 7.Density Dependent and Density Independent. The deltas in India and Indo-China and the Nile Valley provide examples of this type of rich soil. It has also been observed that “two-third of the inhabitants of the temperate zones live in less than 500 kilometres from the sea, and almost one-half of the remainder live in less than 1,000 kilometres inland.”. Institute of Terrestrial Ecology, Banchory, Scotland. Climate is one of the most important natural conditions which have historically played a vital role in the development of hum life, for it is the main factor determining the formation of botany environment and of vegetable and animal associations. However, the geographical distribution of population is greatly unbalanced. 2. Places which are densely populated contain many people. Some are of the view that social and economic factors are more important than physical factors, and that, as society becomes more complex, these physical factors become less important in determining population distribution. Factors Affecting Distribution, Activity and Population of Soil Microorganisms Soil microorganisms (Flora & Fauna), just like higher plants depends entirely on soil for their nutrition, growth and activity. The influences of latitude and altitude on population distri­bution cannot be separated from one another. Short Essay on the Study of Population Distribution by Geographic Areas. Factors Affecting Population Factors Affecting Population Cultural Factors In some cultures and religions, people are respected more if they have many children resulting in an increased birth rate For example, in some cultures having many children is seen as a sign of virility in men. Writing about the distribution of population in pre-partition India on the basis of the 1941 census, Kingsley Davis observes: “In other words, the region’s population is heavily concentrated in the well-watered river and coastal plains.”.
