The age structure of a population refers to the distribution of individuals across different age groups. This distribution is typically represented by an age pyramid, which visually depicts the proportion of young, working-age, and elderly individuals within a population. A population with a large proportion of young people and a smaller proportion of older people is considered to have a young age structure, often characteristic of developing countries with high birth rates. Conversely, a population with a significant proportion of older individuals and a smaller proportion of young people has an aging age structure, common in developed countries with lower birth rates and longer life expectancies.

The age structure of a population has significant implications for various aspects of society, including economic development, healthcare needs, social services, and political dynamics. A young population may require substantial investment in education and job creation, while an aging population places a greater demand on healthcare systems and pension funds. Changes in age structure can also influence consumption patterns, labor force participation, and dependency ratios, which is the ratio of dependents (children and the elderly) to the working-age population. Understanding and analyzing age structure is crucial for effective long-term planning and policy-making at local, national, and global levels.
