Factors That Increase Population Growth

According to sociology, the term "population" is used for a collection of human beings. The size of any population depends upon a number of factors that affect the quality of life and thereby mortality rate. The U.S. Census Bureau stated that as of May 2011, the world population is 6.917 billion. The UN Population Division, in a press release dated March 2007, calculated that the world population would increase by 2.5 billion by the year 2050. Whether such a volume of world population is sustainable or not is another question.

  1. Better Nutrition

    • Food quality is better today. The quality of the food, quantity and the purchase power of people ensure that people eat well and thereby maintain their health better. The ability to eat better food ensures that people live longer lives and are able to produce more children, who also would have a long life expectancy.

    Better Access To Health Care

    • Though people still fall prey to various sicknesses, they have access to better medical care than say a century or two ago. This is another important factor that contributes to the longevity of human beings today, and hence to the increase in population growth.

    Improved Sanitation

    • People are aware of the importance of sanitation in their day-to-day lives. They are also applying all such rules to the methods they cook their food, preserve it, bring up their children and so on. The improved sanitation levels reduce mortality rate considerably both among children and adults.

    Widespread Immunization

    • Immunization against fatal diseases such as Hepatitis B and diphtheria ensure that children stay healthy, live longer and grow into healthy adults. The reduced infant mortality rate also means an increase in population growth. The healthier the children become, the more the population will grow.

    Higher Purchasing Power

    • People are able to make more money today. Though unemployment is still one of the most critical problems worldwide, on an average the purchasing power of the common man has increased manifold. This in turn gives people access to better living conditions, better education, better food --- which in the end means a longer life.

    Better Pest Control

    • There are many animals that in the past caused epidemics that decimated populations across the globe. Some examples are black death, dengue, malaria, cholera and so on. By identifying the vectors and eliminating these from human beings' vicinity, life expectancy is increased and population is increased as well.
