Age classification is a system used to categorize individuals based on their age. This classification helps in various fields, such as education, healthcare, and sports, where age can influence development, abilities, and needs. For example, children may be grouped into different classes in schools to ensure age-appropriate learning. In sports, age classification allows for fair competition by grouping athletes into categories like youth, junior, and senior. This ensures that participants compete against others of similar age, promoting safety and fairness. Age classification can also assist in research and policy-making by identifying age-related trends and issues.
