Demographic Transition in Developing Economies

Steps:

• Development improves healthcare, lowering death rates through better medical access and nutrition.
• Economic growth and education reduce birth rates as families prioritize fewer children with higher quality of life.
• Enhanced living conditions boost worker health and skills, increasing labor productivity.
• These align with the demographic transition model, where mortality drops first, followed by fertility decline.

Why A is correct:

• Matches stage 3 of the demographic transition model: falling birth/death rates due to modernization, with rising productivity from healthier, educated workforce.

Why the others are wrong:

• B: Death rate falls (not rises) with healthcare; productivity rises (not falls) from better conditions.
• C: Birth rate falls (not rises) with development; productivity rises (not falls) via improved human capital.
• D: Both birth and death rates fall (not rise); productivity rises but rates contradict development effects.

Final answer: A
