Middle adulthood is the age between the young adulthood and the old age. There have been several attempts to define this life stages since it occupies more than three quarter of the lifespan of an individual. Middle adulthood has been described to occupy the age between 45 and 60 years (Dacey and Travers, 2005). However, there has not been a consensus on the exact age that is occupied by this period.
For example the United States census defines the middle adulthood as the period between 35 to 54 years, Erickson, how is a renown theorist defined it as period between 40 and 65 years while Brian Boyle, who is also a theorist defines it as a period between 35 and 60 years. Despite the difference in the age definition, middle adulthood is recognized as the period between young adulthood and the onset of old age.
