Explanation:

Age structure diagrams, or population pyramids, are visual tools. Their main purpose is to show how a population's age is distributed. Pie charts (for education levels), infographics (for nationalities), and statistical tables (for wealth distribution) are different from them. These other options focus on aspects like education, nationality, or wealth, not age distribution. So, the correct description is about visual representations of age distribution.

Answer:

visual representations of a population's age distribution
