What is the age range for Adulthood?

Adulthood is typically defined as the period in a person's life that begins around the late teenage years and continues until around the age of 65. The general consensus for the start of adulthood is around the age of 18, as this is when individuals usually gain full legal rights and responsibilities in many countries. While some definitions may slightly vary, the age range of 18 to 65 encompasses the full scope of adulthood, accounting for the transition from young adulthood through middle age.

In this context, the choice that specifies 19 to 65 narrows the starting point of adulthood to slightly later than the widely accepted age of 18. However, it still represents a definition that is commonly recognized, keeping the end of adulthood at 65, which is often considered the upper limit for many discussions concerning adulthood in health and social contexts.

The other choices limit the beginning of adulthood even more to ages 20 or 21, which could omit significant developmental milestones that occur around the age of 18, such as completing secondary education and entering the workforce or higher education. Hence, although they specify an age end of 65, they do not capture the broader understanding of when adulthood begins. Consequently, the choice that marks adulthood starting at 19 acknowledges
