Mirroring larger American trends, a new report finds poverty is split evenly between Chicago and its suburbs.

The “Poverty Matters” report, released today by the Heartland Alliance’s Social IMPACT Research Center, says the suburbs accounted for 34 percent of the area’s poor in 1990. Now, the suburbs are home to 50 percent of the area’s poor…

“We were pretty shocked that it balanced out to 50-50,” said research associate Jennifer Clary. “It definitely flies in the face of the image of affluence in the suburbs.”…

Since poverty is a complex problem, the Heartland Alliance report states there is no single reason for the shift. Causes include growth in low-wage work, stagnating wages and shifts in policies for low-income housing, according to the report…

In the suburbs, the poverty rate increased by 33 percent for foreign-born people, 26 percent for native-born whites, 31 percent for native-born Latinos, and 12 percent for native-born blacks from 1990 to 2011.

Given what is happening elsewhere, these findings shouldn’t been too surprising. But, as the report notes, now the onus is on suburban communities to adjust to changing populations.
