A population pyramid with a narrow base that bulges in the middle and upper sections is observed in a country. This pattern is characteristic of:

• A A declining population with low birth rates and an aging population ✓
• B A stable population with zero population growth
• C A rapidly growing population with high birth rates
• D A population with high infant mortality and high fertility

Explanation

C constrictive population pyramid with a narrow base indicates low birth rates, while the bulge in middle and upper sections reflects an aging population. This pattern is typical of developed countries with below-replacement fertility and increasing life expectancy. An expansive pyramid with a wide base would indicate a rapidly growing population.
