On UN projections between 2015 and 2050, the world population will grow by nearly 2.38 billion people, from 7.35 billion to 9.73 billion. Although this 32% growth is a big increase, it marks a slowdown from the 66% growth rate recorded in the preceding 35 years (1980-2015). Total Fertility Rates (TFRs) have come down all over the world and are expected to continue falling.
