Middle- and low-income households in the U.S. made less money in 2014 than they did in 1999 as the middle class lost ground in almost 90 percent of the country’s metropolitan areas, a new analysis by the Pew Research Center released Wednesday has found.

The report looked at 229 of the 381 federally designated “metropolitan statistical areas” in the U.S., from Seattle to Boston, which accounted for 76 percent of the nationwide population in 2014. It found that poorer households saw their income drop from a median of $26,373 in 1999 to $23,811 in 2014, while middle-class incomes fell from $77,898 to $72,919 in that same time period.

The erosion of the middle class came as household incomes decreased, “a reminder that the economy has yet to fully recover from the effects of the Great Recession of 2007-09,” Pew said—but more than that, it is a reflection of rising income inequality.
