Nearly a third of American families now earn enough to be classified as upper middle class, making it the single largest income group in the country for the first time on record, according to research published by the American Enterprise Institute in January.
The AEI report, authored by labour economist Stephen J. Rose and senior fellow Scott Winship, found 31 per cent of US families qualified as upper middle class in 2024. In 1979, that figure was just 10 per cent.
