What Is Adulthood? Definition, Rights, and Responsibilities

Adult refers to someone who is fully grown or mature, typically in terms of age or physical development. In the context of human development, adulthood is generally considered to begin in the late teenage years or early twenties and lasts until old age. However, the definition of adulthood can vary depending on cultural, social, and legal factors.

In many countries, the legal definition of adulthood is 18 years old, at which point individuals are considered legally adult and are granted certain rights and responsibilities, such as the ability to vote, enter into contracts, and serve in the military. However, some cultures and societies may have different definitions of adulthood based on cultural or religious traditions.
