Explanation
The current age structure of the world’s population means the population will keep growing because of at least 2 reasons:
1. Death Rate Decrease: Death rate is decreasing more rapidly than birth rate, the child mortality rate had dropped drastically from 1-in-5 in 1950 to less than 1-in-20 today.
2. Increase in Average Human Age: This means that people are living longer than before, and if that is the case then population will keep growing
3. An expansive Age Structure of World Population: The world population will keep growing into the near future because it has an Expansive population pyramid which means that a larger percentage of people are in the younger age bracket.
