age structure

Age structure refers to the distribution of different age groups within a population. It is typically represented in a population pyramid, which shows the number or percentage of individuals in various age brackets, such as children, adults, and seniors. Understanding age structure is important because it affects a society's economic growth, healthcare needs, and social services. For example, a younger population may indicate future workforce potential, while an aging population might require more healthcare and retirement services. Analyzing age structure helps policymakers plan for demographic changes and their impacts on society.
