The projections by the United Nations on the world’s population are high, medium and low. The predictions will affect the global community by explaining the factors that influence the growth of population, stagnation, and reduction in the number of people in different places. The trends will, for instance, explain the role of fertility as a powerful determinant of population growth. Considering the policies being made in some countries such as China on one child per family, medium or low population may be seen in that region (Population Reference Bureau, 2013). If family planning education is not provided to families in the third-world nations, then the population is likely to be higher, and it will affect the economies of those communities.
Mortality is the other determinant of population growth. The nations which have relatively high mortality and low life expectations will be expected to improve. Factors resulting in high deaths, such as in infant mortality are being addressed. Women are being educated about prenatal and antenatal care, and the providers are also trained on how to take care of infants. The improvement will result in a high population in low life expectancy nations.

Immigration factor determines population growth in some nations such as the United States (Population Reference Bureau, 2013). America has a significant number of immigrants thus increasing the population. Depending on the world situation, such as continued terrorism in nations such as Afghanistan, the population of America is projected to increase. The country is known to offer asylum to the victims of war and poverty and as long as these issues are not solved immigration will continue. The projections, therefore, will give a guide on the possible increase or decrease in population in different nations across the globe.
