Peak earning years
Peak earning years refers to the time in life when workers earn the most money per year.

US perspective

Given their initial lack of experience, workers' earnings start out low. Earnings peak when workers hit middle age, then begin to fall as retirement approaches. But peak earnings now occur later in life and reach a higher level.

Two decades ago, the peak earning years were between 35 and 44. Now they occur ten years later. Twenty years ago, those in their peak earning years took home about twice as much as workers between the ages of 20 and 24. Now they earn more than three times as much.

In the past, muscle power was an important factor in earnings, but that falters with age. Today, people are paid for working smarter and doing so for a longer period of time.
