Exercise 7

Find three different projections for the size of the global population in 2050 ( Core Case Study ). Explain how the projections were made. To do this, try to find out the assumptions behind each of the projections with regard to total fertility rates, crude death rates, infant mortality rates, life expectancies, and other factors. Based on your reading, choose the projection that you believe to be the closest to reality, and explain why you chose this projection.
