United States middle class shrinks amid rising income inequality

Economic data indicates a significant shift in the American socioeconomic landscape. The middle class, once comprising 62% of national income fifty years ago, has declined to 42%, while the headcount of adults in this bracket has dropped from 61% in 1971 to 51% today.

Income distribution is increasingly concentrated at the extreme top and bottom of the spectrum. This trend is reflected in the widening CEO-to-worker pay ratio, which rose from 60-1 in 1989 to 281-1 in 2024. Analysts note that the lack of a formal government definition for the middle class complicates these assessments.

In terms of the upper-middle class, estimates for 2026 suggest a household income range between $117,000 and $150,000, though this varies significantly by geography. Experts suggest that the transition from middle to upper-middle class is often defined by financial flexibility and the ability to maintain control over time and decision-making rather than income alone.
