INTRODUCTION I. Define Population A population is a summation of all the organisms of the same group or species which live in a particular geographical area and have the capability of interbreeding. The Latin word populous, meaning “people,” gives us the root population. Words from the Latin populous have something to do with people. A population is the group of people living in a particular place. In the future, the world's population is expected to peak, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it is very likely that the world's population will stop growing before the end of the 21st century.
II. What is Population Explosion? Population explosion refers to the rapid and dramatic rise in world population that has occurred over the last few hundred years. Between 1959 and 2000, the world’s population increased from 2.5 billion to 6.1 billion people. According to United Nations projections, the world population will be between 7.9 billion and 10.9 billion by 2050. Most of the growth is currently taking place in the developing world, where rates of natural increase are much higher than in industrialized countries. III.
Causes of Over Population Explosion a) Birth Rate
The term birth rate could be defined as the rate at which the births take place in a population during a particular time or period. Since it is a rate, the involvement of time for the number of births is very important. Usually, the period is defined for a calendar year (from 01st of January to 31st of December of a particular year).

b) Fertility Rate The ratio of live births in an area to the population of that area expressed per 1000 population per year. Fertility rate is generally expressed as the number of births per 1,000 women aged 15-44 in a calendar year. The fertility rate varies significantly across different countries with developed nations have low rates (1 – 2 or 2 – 3 children per female) and developing nations have high rates with sometimes up to 7 – 8 children per woman.
c) Early Marriage/Universal Marriage System Child marriage or early marriage is a formal marriage or informal union entered into by an individual before reaching the age of 18.The legally prescribed marriageable age in some jurisdictions is below 18 years, especially in the case of Page | 2
girls; and even when the age is set at 18 years, many jurisdictions permit earlier marriage with parental consent or in special circumstances, such as teenage pregnancy .
d) Poverty and illiteracy Poverty is general scarcity, or the state of one who lacks a certain amount of material possessions or money. It is a multifaceted concept, which includes social, economic, and political elements. Illiteracy having the maximum influence on increasing poverty causes poverty across the world. Poverty as we all know defined as a miserable state of living condition without the basic needs of life food, clothing and shelter.

IV. Effects of Population Explosion A. Unemployment Unemployment occurs when a person who is actively searching for employment is unable to find work. Unemployment is often used as a measure of the health of the economy. The most frequently cited measure of unemployment is the unemployment rate. This is the number of unemployed persons divided by the number of people in the labour force. B. Manpower utilization i.
Pressure on infrastructure
With the continuing growth in urban population across the globe, both public and private sector stakeholders are coming together to develop and implement solutions that alleviate pressures on existing infrastructure and resources while also enhancing quality of life for urban dwellers. This study highlights steps that are being taken by hardware and software vendors, systems integrators, governments, and other members of the smart city eco-system in creating sustainable solutions that effectively address challenges faced by modern day cities.
ii.
Resource utilization
Population growth impacts on natural resources management, bio diversity conservation, Environment, Health, and socio economic development. Uganda’s population is dependent on the Environment for survival, with 90% of the population involved in agriculture. With population growth, mans activities have increased along mount hills and rivers causing contamination, depletion. As well planning for big populations becomes difficult. All these are a great threat to the environment and accelerators of climatic change.
iii.
Inequitable income distribution
Economic inequality, also known as income inequality, wealth inequality, or the gap between rich and poor is the disparity of any of various measures of economic well-being among individuals in a group, among groups in a population, or among countries. Economists generally focus on economic disparity in three metrics: wealth (wealth inequality), income (income inequality), Page | 6
and consumption. The issue of economic inequality can be relevant to notions of equity, equality of outcome, and equality of opportunity. iv.
Decreased production and increased cost
Every nook and corner of India is a clear display of increasing population. Whether you are in a metro station, airport, railway market, temple, or even in a social/ religious gathering, we see station, road, highway, bus stop, hospital, shopping mall, all these places are overcrowded at any time of the day. According to the Indian census, carried out in 2011, the population of India was exactly 1,210,193,422, which means India has crossed the 1-billion.
V. Reasons for Increase in Population a. Decline in the death rate: At the root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize. Talking about overpopulation shows that while there are many factors that can increase the death rate for short periods of time, the ones that increase the birth rate do so over a long period of time. The discovery of agriculture by our ancestor was one factor that provided them with the ability to sustain their nutrition without hunting. b. Better Medical Facilities: Following this came the industrial revolution. Technological advancement was perhaps the biggest reason why the balance has been permanently disturbed. Science was able to produce better means of producing food, which allowed families to feed more mouths. Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines. Combining the increase in food supply with fewer means of mortality tipped the balance and became the starting point of overpopulation. c. Technological Advancement in Fertility Treatment : With latest technological advancement and more discoveries in medical science, it has become possible for couple who are unable to conceive to undergo fertility treatment methods and have their own babies. Today there are effective medicines which can increases the chance of conception and lead to rise in birth rate. Page | 7
d. Immigration: Many people prefer to move to developed countries like US, UK, Canada and Australia where best facilities are available in terms of medical, education, security and employment. The end result is that those people settle over there and those places become overcrowded. Difference between the number of people who are leaving the country and the number of people who enter narrows down which leads to more demand for food, clothes, energy and home .This gives rise to shortage of resources.
VI. Factors Controlling Population Density a. Geographical factor Physical conditions, such as climate (temperature and rainfall), landforms in terms of altitudes, the quality of the soil and the availability of energy and mine resources are the important geographical determinants of population distribution. Another important factor is the relationship between the location of one place and other places of importance .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. b. Availability of natural resources 1. Fuel: In addition, the cost of transportation and of constructing, maintaining and operating agricultural equipment, is high; and the high altitude also adversely affects human activity and lots of fuel is used. It has been estimated that high mountains, which generally tend to discourage human settlements, occupy more than one million square miles of the earth's land surface.

2. Water Bodies: Availability of water plays a significant role in determining the population of a given area. Water is the basic necessity for several purposes including irrigation, industries, transport and domestic affairs. Rivers are the greatest source of fresh potable water. Therefore, most of the population is concentrated in the river valleys.
3. Mineral Resources: Minerals act as great source of attraction for people from different areas, which results in higher density of population. The higher population densities in the Chota Nagpur Plateau of Jharkhand and in the adjoining areas of Orissa are largely due to the availability of minerals.

4. Social and Economic Factors of Population Distribution: Geographers are not unanimous in their opinion that the distribution of population is determined mainly by physical factors. 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.
VII. Aims and Importance of Population Study Population study is broadly defined as the scientific study of human populations. Major areas studied include broad population dynamics; fertility and family dynamics; health, aging, and mortality; and human capital and labour markets. Researchers in population studies also focus on methodology. Population study Page | 10
is an interdisciplinary area of study; scholars from demography, epidemiology, sociology, economics, anthropology, and various other disciplines study populations. Various associations and centres exist throughout the United States and elsewhere.
VIII. Methodology i. Decline in the Death Rate: The fall in death rates that is decline in mortality rate is one fundamental causes of overpopulation. Owing to the advancements in medicine, man has found cures to the previously fatal diseases. The new inventions in medicine have brought in treatments for most of the dreadful diseases. This has resulted in an increase in the life expectancy of individuals. Mortality rate has declined leading to an increase in population.
ii. Rise in the Birth Rate: Thanks to the new discoveries in nutritional science, we have been able to bring in increase in the fertility rates of human beings. Medicines of today can boost the reproductive rate in human beings. Thus, science has led to an increase in birth rate. This is certainly a reason to be proud and happy but advances in medicine have also become a cause of overpopulation.
iii. Migration: Immigration is a problem in some parts of the world. If the inhabitants of various countries migrate to a particular part of the world and settle over there, the area is bound to suffer from the ill effects of overpopulation. If the rates of emigration from a certain nation do not match the rates of immigration to that country, overpopulation makes its way. The country becomes overly populated.
iv. Lack of Education: Illiteracy is another important cause of overpopulation. Those lacking education fail to understand the need to prevent excessive growth of population. They are unable to understand the harmful effects that overpopulation has. They are unaware of the ways to control population. Lack of family planning is commonly seen in the illiterate lot of the world.

IX. Result and Discussion I think to control populations govt should adopt a policy of one child only it doesn't matter its a boy or a girl. By 2021 India will be very near to china in comparison of population. Friends we say why India is still the developing country. The main reason is populations. If this happen then by any mean India will sure become developed country by 2050 whereas in case of china they will remain the most populated country in the world till 2040 and will also be declined below African countries. In India UP, Maharashtra, Bihar and many other states where populations is increasing tremendously, over there govt should take serious action regarding this issue and should adopt one child policy. Not more than one. If there are twins then it can be ignored.

X. Conclusion What will happen in 2025? Page | 12
While China’s spectacular growth has already benefitted from demographic dividend, India is yet to do so. By 2025 India will be more populous than China. Its population will also be much younger. More than 10 million new workers will join the labour force, every year, for the next two decades. This is equivalent to the entire population of Sweden joining the labour force. The demographic dividend will benefit growth not only through the swelling of the labour force, as the baby boomers reach working age, but also due to society’s ability to save more because working age happens to be the prime years for savings, and the increased fiscal space that will divert resources from spending on children to investing in infrastructure and technology. By 2021 India will be very near to china in comparison of population. Friends we say why India is still the developing country. The main reason is populations. If this happen then by any mean India will sure become developed country by 2050 whereas in case of china they will remain the most populated country in the world till 2040 and will also be declined below African countries.
XI. Population Control Education: Education forms the backbone of an individual and economy. Once educated people know and understand the harms which a high population growth rate possesses. Education, especially women education, can work wonders in Page | 13
controlling population. An educated man and woman can readily understand the benefits of a small family. Without sufficient education most measures like awareness campaigns and women empowerment will prove to be insufficient and pointless. So it is important that people understand the importance of education and educate their children.
Family Planning: India was the first country to adopt family planning (in 1951) as the government sponsored programme. But after the efforts of Indian government for about 50 years, birth rate in India has come down only slightly (only from 41.7 in 1951 to 28.3 in 1997 per 1,000 per year). This showed that voluntary family planning programme was not very successful. In 1976, Indian government thought of introducing a programme of compulsory sterilization which required one parent to undergo sterilization after a couple had produced two children. But due to public resistance, this programme was again changed to voluntary programme.
