Alterszusammensetzung

Alterszusammensetzung refers to the distribution of age groups within a population. This demographic characteristic is a key indicator used in sociology, economics, and public health to understand a society's structure and its potential future trends. Typically, populations are broken down into broad age categories such as children (0-14 years), working-age adults (15-64 years), and the elderly (65 years and over). However, more granular breakdowns are often used for detailed analysis.

The age structure of a population significantly impacts various aspects of a society. A population with a high proportion of young people, often termed a "young population," may face challenges related to education, employment opportunities, and childcare infrastructure. Conversely, a population with a high proportion of older individuals, or an "aging population," may experience increased demand for healthcare services, pensions, and social care.

Factors influencing age composition include birth rates, death rates, and migration patterns. High fertility rates tend to create a younger population, while declining fertility rates and increased life expectancy contribute to an older age structure. International migration can also alter the age distribution, with younger migrants often contributing to a more youthful population. Analyzing the Alterszusammensetzung is crucial for policymakers to plan for social services, economic development, and resource allocation.
