What does a population pyramid primarily indicate about a country?

• A. Economic growth rate
• B. Climate variability
• C. Literacy rates
• D. Age structure and growth prospects

Answer: (D)

A population pyramid shows how a country's people are distributed by age and sex, letting you see the age structure at a glance. The shape tells you about future growth prospects: a wide base means lots of young people and usually rapid population growth with high child dependency, while a narrow base and a broader top indicate an aging population and slower growth with higher elderly dependency. It also reveals the balance between males and females in different age groups. This is not a direct measure of climate variability or literacy rates, and while age structure can influence long-term economic growth, the pyramid itself is a picture of who is young, who is old, and how fast the population is likely to change.
