Middle adulthood is the developmental period that begins at approximately 40 to 45 years of age and extends to about 60 to 65 years of age.
More about middle adulthood:
The stage of life between early adulthood and late adulthood is known as middle adulthood, often known as midlife. Although there are cultural differences in how people define ages and tasks, the most typical range is from 40–45 to 60–65.
As many parts of midlife are still being investigated, this may be the least researched period of the lifespan, and study on this developmental stage is relatively recent.
Because the enormous Baby Boom cohort—those born between 1946 and 1964—are now in their mid- to late-life years in the United States, there is more interest in this developmental stage.
