White men who work full-time grabbed the smallest share of economic growth of any other demographic, the researchers found. The median income for these workers stood at $57,000 in 2018, but they would have earned $109,000 if they had kept pace. According to Rand's calculations, their incomes grew by about one-tenth of the nation's economic growth from the mid-1970s until 2018.

That share of economic growth trails the amount captured by White women, Black men and women and Asian men and women, the study noted.
