Chicago didn’t become poorer. It became polarized.

A city without a middle class isn’t diverse. It’s fragile.

Urban “growth” now rewards wealth concentration while taxing stability out of existence.

BRIEFING

Grant here. Throughout the United States and over the last decade, we've seen a big breakdown in the middle class, but Chicago just became the ultimate example of this collapse. Let’s break it down.

Chicago’s middle class didn’t just vanish overnight. Like many other American cities, it was slowly erased through policies that rewarded concentration at the top and dependency at the bottom, while making ordinary stability harder to sustain.

The maps and data tell the story of this decline clearly. In 1970, large portions of Chicago were middle-income. By 2017, those areas had thinned dramatically, and what replaced them wasn’t broad prosperity but a split city. Wealth clustered tightly in select neighborhoods, while poverty expanded across many others. Then the middle, the group that pays taxes, maintains homes, and anchors communities, was squeezed out.

Chicago’s Middle Class Is Disappearing: “The middle class is declining because the top 10% is swelling” in the city, says demographer Rob Paral, “& the bottom 20% is swelling. In a place like North Center, the median income is going through the roof” https://t.co/lIrH5nkdlB pic.twitter.com/XwwBX1bLMi

And you won't find this degradation of the middle class just from this chart but also from well-cited research.

The University of Illinois Chicago’s Voorhees Center documents just how dramatically Chicago’s income structure has shifted over time. Their neighborhood-level analysis shows that middle-income communities have steadily disappeared, replaced by a growing concentration of wealth in some areas and expanding low-income zones in others. The data doesn’t describe a city getting richer or poorer overall; it illustrates a city losing balance, where the middle is no longer economically viable in large parts of Chicago.

There’s a map that, like so many other Chicago maps, charts the decline of the middle class in the city. In 1970, nearly half of the city’s census tract were identified as middle income. Now, the few middle-class neighborhoods left are in the Northwest and Southwest corners of the city, where city workers with middle-income jobs — teachers, firefighters, nurses — tend to cluster. The South and West sides are almost all lower income. And there’s a new element: high-income neighborhoods, which have expanded from a thin strip along the lakefront in 1970 to consume almost the entire North Side today. According to the Pew Research Center, the nation’s share of middle-income families has declined from 61 percent to 51 percent over those years. The middle-class squeeze seems even more pronounced in Chicago.

“The middle class is declining because the top 10 percent is swelling” in the city, says demographer Rob Paral, “and the bottom 20 percent is swelling. In a place like North Center, the median income is going through the roof.”

That’s part of a nationwide trend. In the same time period displayed by those maps, the share of income earned by the top 10 percent has increased from 33 percent to nearly 50 percent, according to the Economic Policy Institute. Increasingly, those high earners want to live in cities, which is a big change from the 1970s and ’80s, when people with money were fleeing urban America for suburban America. Since 2000, the fastest-growing concentration of $200,000-plus earning households is on the former site of the Cabrini-Green housing projects, which has replaced blight with condominiums, gyms, movie theaters and a Mariano’s. The city’s fastest-growing neighborhoods are also its wealthiest. The Loop, with a median household income of $119,837, has nearly doubled in population since 2010. Meanwhile, the population of Edison Park, one of the few remaining middle class neighborhoods, has been completely flat. Englewood, one of the city’s poorest, has lost half its population since 2000. The city isn’t building middle class housing, as it did during the era of bungalows and two-flats. It’s building the Aqua Tower, it’s building the St. Regis, and it’s building affordable housing. In 2025, the city invested $137 million in affordable housing and opened 561 affordable units.

Last year, 156 homes sold in the Chicago area for more than $4 million, beating the previous record of 136. More than half were in the city.

DEBRIEFING

Put the maps and the data together, and the full picture here becomes unavoidable. Chicago didn’t lose its middle class because residents suddenly failed to work hard enough or make smart choices. But this once great city lost its middle class because the city stopped being structured for ordinary life.

When housing, taxes, and basic living expenses rise faster than wages, the people in the middle don’t fall down, but they adjust and try to survive in the only way they can. Which subsequently leaves only one option: move out.

Neighborhoods didn’t gradually improve or decline together; they literally split down the middle. With wealth concentrated tightly in a handful of areas while poverty spread across others. The middle, the space where teachers, tradesmen, nurses, small business owners, and city workers once lived, simply stopped being supported.

And sadly, Chicago isn’t an outlier, but it’s certainly an extreme warning. One that's growing at a rate that other cities will surely catch up to.

NOW YOU KNOW

This isn’t a decline by accident. It’s erosion by design.
