The developing world's population pyramid tends to be primarily triangular because of a large youth population. Which option best matches this description?

• A. Diamond shape
• B. Triangle shape
• C. Rectangular shape
• D. Inverted pyramid

Answer: (B)

Population pyramids show how many people are in each age group. When a country has many births relative to deaths, there are a lot of young people, so the bottom of the pyramid is wide and it narrows quickly with age, creating a triangular shape. This reflects a large youth population typical of many developing nations. The other shapes describe different patterns: a diamond would indicate a bulge in middle ages, a rectangular shape suggests a stable, evenly distributed population across ages, and an inverted pyramid would mean more older people than younger. So the triangle shape best matches a population with a large youth cohort.
