Stage 3 of the Demographic Transition Model is characterized by which trend?

• A. Birth declines while death remains low.
• B. Birth remains high while death declines.
• C. Birth and death both low.
• D. Birth declines and death increases.

Answer: (A)

Stage 3 shows fertility falling as societies urbanize and people adopt smaller family sizes, while health conditions remain good and death rates stay low. With improved medicine, sanitation, and overall living standards, death rates are already low, so the main change is in births: fewer children are born because of factors like education, women's empowerment, and access to contraception. That combination—birth rates decreasing while death rates stay low—leads to slower population growth compared to Stage 2. If births stayed high while deaths remained low, the population would grow very rapidly (characteristic of Stage 2). If both birth and death rates are low, the population growth levels off (Stage 4). A scenario where births decline and deaths rise would indicate worsening health conditions, not typical of the transition being described.
