How does pay growth after age 35 differ across earnings brackets?
Core argument: Top lifetime-earnings workers saw earnings rise 435% between ages 25 and 35, versus over 65% for median earners and 16% for those at the bottom.
At age 25, individuals in the lowest lifetime earnings (LE) bracket earned an average of approximately $12,000, while those in the median and top brackets earned $28,000 and $39,000, respectively. As a result, the earnings gap between the highest and lowest earners—measured as the ratio of their average earnings—already stands at around 3.25 at the beginning of their working lives. Those at the top of the LE distribution witness a remarkable 435% surge in their incomes between ages 25 and 35. In contrast, median earners undergo a comparatively modest increase of over 65%, while those at the bottom experience minimal earnings growth, a mere 16% uptick. Interestingly, during the subsequent 10-year period (ages 35-45), the median LE group witnesses a significant deceleration in their earnings growth, plummeting from the previous decade’s 65% increase to approximately 15%. Meanwhile, the bottom LE group continues to undergo a gradual but consistent earnings growth of around 15%. The top LE group deviates substantially from the rest of the workforce. They once again experience surge in earnings, exceeding 150%, and by the time they reach age 45, they earned more than half a million dollars annually. Consequently, the earnings gap between the highest and lowest earners widens further, expanding from 15.3 to 33.1.
