Which factor has played a major role in the population growth of
emerging societies?



Better health standards.

Explanation:

When emerging populations are in a position to obtain good health standards, such as adequate food, water in correct quantity, good quality of life and medical care whenever necessary, there is an increase in the birth rate of this population, which extends through the years, along with increased life expectancy. As a result, population growth is stimulated and the population has a fast and efficient population.
