Read each question carefully and answer to the best of your ability. Refer to the provided population graph examples to help you analyze and respond.
Population pyramids are graphical illustrations that show the distribution of various age groups in a population, which forms the shape of a pyramid when the population is growing. It also shows the sex ratio (the number of males per 100 females) and dependency ratio (the ratio of dependents—people younger than 15 or older than 64—to the working-age population—those aged 15–64).
1. What type of information does a population pyramid primarily display?
Economic growth of a country
Age and sex distribution of a population
Annual rainfall in a region
Types of industries in a city
2. A population pyramid with a wide base and narrow top indicates:
A rapidly aging population
High birth rates and rapid population growth
A stable population with low birth and death rates
A population in decline
