What are the ages categorized as young adulthood?

• A. 20-40
• B. 18-30
• C. 25-45
• D. 30-50

Answer: (A)

Young adulthood is defined by the life tasks people typically pursue after adolescence: gaining independence, establishing a career or continuing education, forming intimate relationships, and often starting families. This set of experiences is most common from about age 20 up through the early to mid-40s, with peak independence and stability usually spanning the 20s and 30s and a gradual transition as people approach 40. Boundaries around 40 reflect a shift toward middle adulthood in many models, so this range best captures the period where those core responsibilities are most characteristic.

Other ranges tend to cut off part of this period or extend into ages more associated with middle adulthood—for example, including younger teens, omitting the late 20s/early 30s, or reaching into the 40s and 50s—which makes them less representative of young adulthood.
