  1. DEMOGRAPHIC PROBLEMS

  2. POPULATION • In sociology, population refers to a collection of human beings. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population. • As of today's date, the world population is estimated by the United States Census Bureau to be 7.003 billion. • According to papers published by the United States Census Bureau, the world population hit 6.5 billion (6,500,000,000) on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion.

  3. POPULATION GROWTH • Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. The last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity, particularly beginning in the 1960s, made by the Green Revolution. In 2007 the United Nations Population Division projected that the world's population will likely surpass 10 billion in 2055.

  4. DECLINE IN POPULATION • According to one report, it is very likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will actually decline before 2100. Population has already declined in the last decade or two in Eastern Europe, the Baltics and in the Commonwealth of Independent States. • The population pattern of less-developed regions of the world in recent years has been marked by gradually declining birth rates following an earlier sharp reduction in death rates. This transition from high birth and death rates to low birth and death rates is often referred to as the demographic transition.

  5. OVERPOPULATION • At present, there are 6.5 billion people in the world and the number continues to multiply. In contrast, there are only a limited number of natural resources. On a global basis, the human population has shown a J-shaped pattern of growth over the past two thousand years, while the availability of natural resources mandatory for human survival is in slow decline. The implications of this are not limited to mass starvation, poverty and overcrowding of poorly sanitized cities. In fact, the current stress created by the imbalance between a burgeoning population and a finite number of resources are also one of the main factors contributing to the rise of violent inter-group conflict. Clearly, something must change in order to insure our own survival and the survival of our planet.  • Unfortunately, human nature adopted its current manufacture and consumption habits during a time when the balance between the number of humans and their available resources was not nearly as stressed. 

  6. AGEING OF POPULATION • Population ageing occurs when the median age of a country or region rises. This happens because of rising life expectancy or declining birth rates. Excepting 18 countries termed 'demographic outliers' by the UN, this process is taking place in every country and region across the globe. In the entirety of recorded human history, the world has never seen as aged a population as currently exists globally. The UN predicts the rate of population ageing in the 21st century will exceed that in the 20th. Countries vary significantly in terms of the degree, and the pace, of these changes, and the UN expects populations that began ageing later to have less time to adapt to the many implications of these changes.

  7. INFANT MORTALITY • Infant mortality is babies who die during the first year of their life. In 2002 there were 7.2 million infant deaths worldwide; 5.4% of all babies born died within their first year, including 2.3% in their first week. • The territory with the most infant deaths was India, at 1.7 million, or 24% of the world total. In India, for every 100 babies born alive, almost 7 die in the following 12 months. • In 22 territories the rate is over 1 infant death for every 10 live births. All of these 22 territories are in Africa. The highest infant mortality rate is in Sierra Leone where 16.5 babies die, of every 100 born alive.

  8. Population projections (INDIA) India is projected to overtake China as the world's most populous nation by 2030. India's population growth has raised concerns that it would lead to widespread unemployment and political instability... The population projections of India are as follows : 2020: 1,326,093,000 2030: 1,460,743,000 2040: 1,571,715,000 2050: 1,656,554,000

  9. IMPACT OF OVERPOPULATION ON ENVIRONMENT • Overpopulation causes unmanageable pollution, improper use and distribution of natural resources, increase in crime rates and overall lower quality of life. • There are quite a few very specific negative effects of overpopulation to nations. One of the most obvious effects is the substantial increase of pollution or garbage, especially solid waste. Air pollution also increases because industrial factories have to multiply in number or scale in order to meet the demands of the population.
