korösszetétele

Korösszetétele, also known as age structure or age composition, is a demographic term that describes the distribution of a population by age. It is a crucial component of population studies and is often used to analyze the demographic characteristics of a region, country, or community. The age structure of a population can significantly influence various aspects of society, including economic development, social policies, and healthcare systems.

The age structure is typically represented in a population pyramid, which is a graphical representation of the age distribution of a population. The pyramid is divided into male and female segments, with the youngest age groups at the base and the oldest at the top. The shape of the pyramid can provide insights into the demographic trends of a population, such as whether it is growing, stable, or declining.

There are three main types of age structures:

1. Expanding population: Characterized by a large proportion of young people, indicating a growing population.

2. Stationary population: Has a relatively equal number of people in all age groups, suggesting a stable population.

3. Declining population: Features a large proportion of older people, indicating a shrinking population.

Korösszetétele is an essential tool for policymakers, researchers, and planners to understand the demographic dynamics of a population and to make informed decisions regarding resource allocation, social services, and economic development. It is also used to compare the demographic characteristics of different regions or countries and to identify trends and patterns in population growth and aging.
