At what stage of life does a person transition from child to adult?

The transition from child to adult is most commonly recognized to occur at puberty. This is a significant stage in human development marked by various physical, emotional, and social changes that signify the onset of adolescence. During puberty, individuals undergo hormonal changes that lead to the development of secondary sexual characteristics and a range of other physiological changes.

This period is crucial as it also encompasses an increase in independence and the ability to take on more complex roles in society. Psychologically and socially, individuals begin to seek identity, form deeper relationships, and develop their personal values, which are all key aspects of adult life. While legal definitions of adulthood, such as reaching the age of 18, do exist, the biological and developmental changes associated with puberty lay the foundation for this transition, making it a vital stage in the journey from childhood to adulthood.
