IGCSE Population Case Studies Practice Test

A population pyramid is a graphical representation that displays the age and gender distribution of a given population. It is particularly effective for illustrating not only the distribution of various age groups but also the growth trends of the population over time. The two columns of the pyramid typically represent males and females, with the youngest age groups at the bottom and the oldest at the top.

By analyzing the shape and structure of the pyramid, one can determine whether a population is growing, stable, or declining. For instance, a wider base suggests a higher birth rate and potential for future growth, while a more uniform shape may indicate stability or low growth. Conversely, a narrower top may reflect higher mortality rates or an aging population. This information is critical for policymakers, demographers, and social planners who need to anticipate the needs of different age cohorts in the population, such as education, healthcare, and employment strategies.

In contrast, the other options are focused on economic and political aspects rather than demographic characteristics, making them less relevant in the context of what a population pyramid conveys. This reinforces the understanding that the primary purpose of a population pyramid is to illustrate age structure and growth trends.
