Age distribution refers to the way different age groups are represented within a population. It is often displayed in a graph or chart, showing the number of individuals in various age ranges, such as children, adults, and seniors. Understanding age distribution helps in analyzing demographic trends and planning for resources like education, healthcare, and retirement services. This concept is crucial for governments and organizations to address the needs of different age groups. For example, a population with a high percentage of young people may require more schools, while an aging population may need increased healthcare services for seniors.
