This statement is true. According to the United Nations, the global fertility rate in 2015 was 2.5 children per woman. If this rate were to decrease to 1.5 children per woman, the world population in 2150 is projected to be around 3.6 billion. If the fertility rate were to increase to 3.5 children per woman, the population is expected to reach 27 billion. Therefore, a difference of only 1 child per woman can have a significant impact on the world population.
