The Black Family Exodus From Chicago, Illinois.

Via WGN,
COOK COUNTY -- Cook County has the largest African-American population in the U.S., but according to the Chicago Tribune, census data shows black residents are also leaving the county at an increasing rate.
Between 2015 and 2016, more than 12,000 black residents moved out of Cook County, an increase from 9,000 the year before.
Experts say people are leaving due to high taxes, high crime, and weather. These Black Families are in search of jobs and safe neighborhoods. These are things that Chicago is not offering them anymore.

The general population in Illinois dropped by more than 37,000 people last year, more than any other state.
People move from the city to the suburbs for a host of things ... But I wouldn't expect those people to move from a whole metropolitan area. Something bigger's going on.— William Frey, demographer with the Brookings Institution
