korösszetételére

Korösszetételére refers to the age structure of a population. It describes the distribution of individuals within a population across different age groups. This demographic characteristic is crucial for understanding a population's dynamics, including its growth rate, dependency ratios, and future needs.

Typically, age structure is represented by an age pyramid or population pyramid. These graphical representations show the number or proportion of people in each age group, usually divided into five-year intervals, and often separated by sex. A pyramid with a broad base and a narrow top indicates a young population with a high birth rate and potentially rapid growth. Conversely, a pyramid with a more rectangular shape or a wider top suggests an aging population with lower birth rates and slower or negative growth.

The age composition of a population has significant implications for various societal aspects. A young population may require more resources for education and childcare, while an aging population will place greater demand on healthcare, pensions, and social support systems. Changes in age structure can also influence the labor force, consumption patterns, and even political landscapes. Factors such as birth rates, death rates, and migration patterns all contribute to shaping a population's korösszetételére over time. Analyzing this structure helps policymakers plan for future demographic shifts and allocate resources effectively.
