Final answer:
Education plays a crucial role in addressing the need for replenishing the population by influencing birth rates. As women gain better education and control over their reproduction, birth rates decrease.
Step-by-step explanation:

This demographic shift has been observed in developed nations where family sizes have decreased due to increased economic security and education.
