Here's a story that flips the usual economic doom narrative on its head. The middle class is shrinking, sure. But according to new research from the American Enterprise Institute, it's not because American families are struggling. It's because they're earning more money.

Researchers Scott Winship and Stephen J. Rose analyzed income data stretching back to 1979 and found something surprising. Yes, the core middle class has gotten smaller over the past four decades. But that's only because huge numbers of families have climbed into higher income brackets. "What we see, then, is not a hollowing out of the middle class but a booming upper-middle class," the report explains.

The Upper-Middle Class Has Tripled

The numbers tell a pretty remarkable story. Back in 1979, just 10% of American families qualified as upper-middle class. Today, that figure stands at 31%. Meanwhile, the core middle class shrank from 36% to 31% of the population during the same period. For the first time ever, more families now sit above the middle class than below it.

The researchers defined these income groups using consistent purchasing power, accounting for both inflation and family size. What they discovered was that the number of poor or near-poor families dropped dramatically, falling from 30% in 1979 to just 19% in 2024.

"The shrinking core middle class is due to a booming upper-middle class," the authors note. "Only the relatively worse-off parts of the middle class have shrunk—and by less than the upper-middle class has grown."

Translation: families didn't slide out of the middle class by getting poorer. They graduated out of it by earning more.

Income Gains Across the Board

Even families at the lower end of the income spectrum are better off than they were decades ago. According to the AEI report, adjusted median family income jumped 52% between 1979 and 2024. Families at the 10th percentile of the income distribution are nearly 30% better off than their counterparts were 45 years ago.

Now, the gains weren't exactly distributed evenly. Higher earners saw much faster income growth. The top 1% of earners increased their share of national income from 5% to 9%. The richest families now collect 19% of all income, compared to just 2% in 1979. Still, the data shows measurable improvement at every income level.

This directly contradicts the narrative you hear from politicians and pundits on both sides of the aisle. The "shrinking middle class" has become shorthand for economic failure. But as the AEI researchers point out, "decrying a shrinking or hollowed-out middle class is just a gloomy way of saying the upper-middle class has boomed and fewer families are in hardship."

What This Means For American Families

The shift in America's income distribution creates new challenges and opportunities. As more households cross into upper-middle-class territory, their financial needs become more complex. Managing higher incomes effectively requires different strategies than simply making ends meet.

The big picture here is that the American income ladder has changed shape. The middle class may be smaller in percentage terms, but that's not because families are falling behind. It's because they're climbing higher. The economic story isn't about a disappearing middle class. It's about an expanding upper-middle class and a shrinking number of families in poverty.

Sometimes the gloomy headline hides a more optimistic reality. This appears to be one of those times.
