In the Demographic Transition Model, which stage is characterized by a rapid population increase due to falling death rates while birth rates remain high?

• A. Stage 1
• B. Stage 2
• C. Stage 3
• D. Stage 4

Answer: (B)

In this model, the stage described is one where death rates fall rapidly while birth rates stay high, causing the population to grow quickly. That happens because improvements in medicine, sanitation, and food supply reduce mortality, especially among children, but cultural norms and limited access to contraception keep birth rates high. So a surge in population follows as more people survive, even though families continue to have many children. The other stages don’t fit as well: earlier stage has high birth and death rates with little population growth; a later stage sees birth rates decline and eventually fall to match low death rates, stabilizing or slowing growth; and the final stage features low birth and death rates with near-stable population.
