korösszetételt

Korösszetétel refers to the age structure of a population. It describes the distribution of individuals within a population across different age groups. This distribution is typically categorized into three broad segments: the young, the reproductive age group, and the elderly.

Understanding the korösszetétel is crucial for demographic analysis and planning. A population with a high proportion of young individuals, often referred to as a "young population," typically indicates high birth rates and a potential for future population growth. Conversely, a population with a large proportion of elderly individuals, known as an "aging population," suggests lower birth rates and potentially a declining population, with implications for healthcare, social security, and the labor force.

The korösszetétel of a population is influenced by various factors, including fertility rates, mortality rates, and migration. Changes in these factors over time lead to shifts in the age structure. For instance, a decline in fertility rates will gradually lead to a smaller proportion of young people and an increase in the proportion of older age groups.

Demographers often visualize the korösszetétel using population pyramids, which graphically represent the number or proportion of individuals in different age and sex groups. These pyramids provide a clear overview of the population's age distribution and can reveal trends and potential future challenges. Analyzing the korösszetétel helps policymakers and researchers make informed decisions regarding education, employment, retirement, and social services.
