What does a population pyramid illustrate?

• A. Population growth rate
• B. Migration patterns
• C. Economic indicators
• D. Age and sex distribution

Answer: (D)

A population pyramid shows how a population is distributed by age and by sex. It’s a two-sided bar graph where each horizontal bar represents an age group, with one side for males and the other for females. This layout lets you see the shape of the population: a wide base means many young people and usually high birth rates, while a wider top indicates an aging population. The differences between the two sides reveal the sex ratio at each age. In short, it illustrates age structure and gender composition, not just growth rate, migration, or economic indicators.
