What are the age structures of representing nongrowing slowly growing and rapidly growing countries?

The age structure of nongrowing countries typically features a larger proportion of older individuals, indicating low birth and death rates, often leading to an aging population. Slowly growing countries exhibit a more balanced age distribution, with a significant number of individuals in the working-age group and a moderate proportion of young and elderly individuals. In rapidly growing countries, there is a high percentage of young people, often accompanied by high birth rates, resulting in a youthful population structure with a potential demographic dividend if adequately supported by economic opportunities.
