When the Tribune looked at the demographics of people who moved out of state from the Chicago area — Cook, DuPage, Kane, Lake, McHenry and Will counties — it found the income and racial breakdowns for this group generally mirrored the patterns of the overall population in the area. Most of the movers made $50,000 or less in income, and most were white non-Hispanic, according to census survey data collected from 2013 to 2017.
