Middle adulthood spans which age range?

• A. 40-65
• B. 20-40
• C. 30-50
• D. 50-70

Answer: (A)

Middle adulthood is typically defined as roughly ages 40 through 65. This stage sits between young adulthood, when people focus on establishing careers and families, and late adulthood, when aging becomes more pronounced. The 40–65 window captures midlife transitions such as re-evaluating life goals, potential career changes, children becoming independent, and the start of physical aging, which is why it’s the reference range used in many psychology texts and practice questions.

Other ranges don’t fit as well because they place the period in different life stages. For example, 20–40 sits in young adulthood, before many midlife changes occur; 30–50 blends late young adulthood with early middle life and misses later midlife; 50–70 starts in late middle and extends into older adulthood, omitting the earlier part of middle life.
