Two countries have equally ambitious population policies. In Country A, fertility declines significantly, while in Country B, fertility remains relatively high despite similar policies. Which explanation best accounts for this difference?

Differences in economic, social, and cultural change

The correct answer is Option 2: Differences in economic, social, and cultural change.

Population policies do not operate in isolation. Their effectiveness depends heavily on social conditions such as education, gender relations, cultural norms, economic opportunities, and public attitudes towards family size. Similar policies can therefore produce different outcomes in different social contexts.
