What Age Is a Young Adult?

As people age, they are placed into different age categories. Age categories typically involve adolescence, young adulthood and later adulthood. According to the MIT Center for Work, Family & Personal Life, young adulthood is considered a developmental period. Young adulthood is often referred to as "emerging adulthood." Young adulthood is often viewed as a period of time where individuals continue to change and learn a number of important life skills.
