Age dynamics refers to the changes in population structure and characteristics over time, particularly concerning different age groups. It examines how factors like birth rates, death rates, and migration influence the distribution of ages within a population. Understanding age dynamics is crucial for planning in areas such as healthcare, education, and workforce development. The concept also highlights the impact of aging populations, where a higher proportion of older individuals can lead to challenges like increased healthcare needs and pension sustainability. Conversely, a younger population may present opportunities for economic growth and innovation, as seen in regions with a high concentration of young professionals.
