Factors influncing Population Distrbution & Population
Density
Introduction:
World’s total population i.e. total human beings living on
this planet earth has crossed the 7 billion mark. According to various
statistics, it has been found that the Least Developed Countries (LDCs) is a
home to 82 % of the world’s population whereas the remaining i.e. 18% live in
Most Developed Countries. This huge population is not distributed evenly
throughout the world as the continent of Asia is home of around 4 billion
people, Africa 1 billion, Europe 733 million people, Latin America and
Caribbean 589 million, North America of 352 million and Australia and
Antarctica combine 35 million people. Not a single factor is responsible for
this variable distribution and density of Population.
Factors influencing Population
Density and Population Distribution:
Geographical Factors:
Availability of Water:
It is one of the main factor which force people to settle in
a particular area as water is used for drinking, crops growth, cattle breeding
etc.
Landforms:
People prefer to live in plain areas as these areas are easy
to access, and are feasible for communication, agricultural and industrial
activities.
Climate:
Another important factor for dense population in an area is
climate. People prefer to live in areas which have moderate climate-thus
avoiding extreme climates like that in Antarctica.
Soil:
Most of the people who are linked with agriculture prefer to
live in areas which are fertile.
Economic Factors:
Urbanization:
Better job opportunities, education and health facilities
are also responsible for dense population in a limited area. Urban cities are
densely populated as it has all these facilities. To name a few, Tokyo, London,
New York, Dubai are some of the famous cities in the world.
Minerals:
Areas rich in minerals attract people interested in mining
activities and thus companies of international standard which in turn attract
people in search of jobs thus increase in population of that area.
Industrialization:
Industries not only require labors but also operators,
management staff, engineers, doctors etc as it has its own residential area.
Need for High Income:
Farmers in agricultural areas require larger work force to
increase crop yield and income. They do not think about increased population.
Social/Cultural Factors:
Religious Cultural Factors:
Islam and Christianity strongly criticize family planning
therefore; people who are very religious minded do not care for increased
population. People try to live at places where people of same culture are
present.
Lack of Education:
Lack of education is also one of the greatest factors of
increase in population as people are unaware of the economic burden, increased
population put on country’s economy.
Government Policies:
Frequent government changes results in inconsistency of
policies against high population growth rate. The government of France now
gives incentives to the parents for giving births to more children as their
population growth rate is now negative.
Age of Marriage:
In the Least Developed Countries (LDCs), females get married
at very young age and this also contributes to high population growth in Least
Developed Countries.
Wish for a Boy:
People also wish for a baby boy who would be a source of
income for the parents in their old age. In wish of a boy, sometimes people
have more daughters as well.
Decrease in Death Rate:
The advanced medical facilities have caused decrease in
death rate which has also contributed to the increase in population density.
Political Unrest or War:
Areas which are involved in war or are experiencing
political unrest, people tend to move from that areas which result in less
population at one and increase in another area.
Effects of Overpopulation:
Overpopulation in one way or the other has many adverse
effects. Some of the main effects are as follows:
- Increases
in noise pollution, water pollution, air pollution, soil contamination.
- Reduction
in natural resources.
- Deforestation,
changes in atmospheric composition.
- Loss
of arable land.
- High
infant and child mortality due to poverty.
- Emergence
of epidemics and pandemics.
- Standard
of living reduced and crime rate increases for survival.
- Increased
conflicts over scarce resources.
