Stage 3 of the demographic transition demonstrates what trend?

Stage 3 of the demographic transition model is characterized by significant social and economic changes that lead to a decline in fertility rates while mortality rates continue to decrease. This stage represents a shift towards greater urbanization, improved health care, and enhanced educational opportunities, especially for women.

As fertility rates drop, families tend to have fewer children, which results in a more even age distribution across the population. This is often coupled with changes in societal values regarding family size and child-rearing practices. Increased access to contraception and a greater focus on careers and education also contribute to this trend.

The population becomes more balanced in terms of age and sex distribution, as both birth and death rates stabilize. This is in contrast to earlier stages where higher fertility rates result in a younger population composition. Thus, the trend observed in Stage 3 reflects a demographic shift that is essential for understanding population dynamics and planning for services required to support an aging population.
