Which stage of the Demographic Transition Model is characterized by high birth rates and declining death rates, leading to rapid population growth and significant social change?

The stage of the Demographic Transition Model that shows high birth rates and declining death rates is called Stage 2. In this stage, people still have many children, but improvements in healthcare and sanitation reduce the number of deaths, especially among infants. This combination leads to rapid population growth, as more people are living longer and healthier lives. For example, in many countries in Africa, families may have several children while medical advancements help more of those children survive to adulthood. This situation often brings about significant social changes, such as shifts in family structure, education, and economic opportunities.
