Areas with particularly dense rainforest, coniferous forests or those with little vegetation tend to have sparse populations. Mountainous areas with steep slopes and poor quality soil tend to have low population densities. Singapore Unstable countries tend to have lower population densities as people migrate e. Deaths, on the other hand, reduce the population size, thus decreasing the total population. The most appropriate example of temperature affecting population distribution is the one provided by the Arctic and Subtract Regions where, because of long and very cold winter nights and low intensity of solar radiation even during the summer, living conditions are extremely difficult and the energy of human beings is spent mainly on struggling against the difficult conditions created by nature.
Of all the climatic factors, twin elements of rainfall and temperature play the most important role in determining the population of an area. In other words, it's not crowded. Climate A climate which is not too extreme in either direction often encourages the greatest settlement growth. Like I said earlier, I live in the Northeastern U. 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. Various factors are employed to chart the population growth of species in order to ensure that it doesn't have any untoward effect on the ecosystem. Similarly, for herbivores, the limiting factor on the southernmost continent is the lack of vegetation.
This results in higher concentration of population. If more individuals are added than lost, then the population will show positive growth. Many industries have to be set up in proximity with the consumers of their products; conversely, wherever population concentration is great, such industries are set up. The existing population distribution sometimes acts as a demographic factor which attracts the setting up of certain industries, which in turn results in further development of the area and encourages concentration of population. D is explaining why unhealthy environments… 744 Words 3 Pages requirements of being an American citizen, and the age of 18 then he or she can vote.
Similar to birth rates, the death rate is also often described as a percentage of the population. Industries: Industrial growth offers massive employment opportunities and acts as a great magnet to attract people, particularly from the neighbouring areas. The Population Growth Rate Although there are factors that either increase or decrease the human population, when these factors are combined, they represent the overall population growth rate. In that scenario, the human population on Earth would increase. Relief and landforms Lowland plains, flat river valleys and deltas and volcanic areas with fertile soil tend to have high population densities. The tables below illustrate this.
It's a close-knit community where the majority of people share the same ethnicity. Singapore Unstable countries tend to have lower population densities as people migrate e. For this reason, when we first moved here, we were viewed a bit suspiciously since our Southern accents didn't quite jive with their German heritage. The term most commonly used when describing natality in the human population is 'birth rate'. In more recent times, several Middle East countries have allowed and have even encouraged immigration from neighboring developing countries to man several skilled well as semi-skilled and unskilled jobs. This cause formerly inhabited areas to become sparsely populated while new settlement realize an increase in population. For example, rodents called lemmings respond to high population density by emigrating in groups in search of a new, less crowded place to live.
A number of factors can affect population density. On a grander scale, you can see ethnicity affecting population distribution with how common neighborhoods like Chinatowns are in major cities, or the Irish pubs that line the streets of Boston. This is a simple yet effective way of showing how area, population in whole and if they population can move anywhere else effect the population density. Population pyramids for every country in the world can be found. Brasilia and the development of the Trans-Amazonian Highway in Brazil; the movement of Han Chinese to Tibet; the development of Abuja as a new capital city in Nigeria. 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. On one hand the population of India is highly concentrated in some pockets such as highly urbanized and industrialised areas and areas of high agricultural productivity, while on the other hand there are virtually demographic deserts in high mountains, arid lands, thickly forested areas and some remote corners of the country.
The darker the colour the greater the population density. The Assam valley in the north-east and the Circars coast on the Bay of Bengal has moderate density of population although these areas receive heavy rainfall. Vegetation is and influential factor as well. Some government program mes may require the removal of people from certain areas in order to settle them in new areas. 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.
This rapid growth in population has been called a population explosion. More than any other mineral, coed attracts industries and resultant population concentration. 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. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. This reduced population in these areas. Limited job opportunities cause some areas to be sparsely populated e. It gives them a clearer idea of the kind of care that they should expect to be giving local people and the health concerns that they may be dealing with.
