The age structure of a population refers to the categorization of the world's population into age groups.
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. This further implies that there will be high fertility rates because young people are more likely to reproduce than the aged.
