The majority of municipalities in the Chicago region, including the city itself, lost population last year, according to newly released estimates from the U.S. Census Bureau. After losing an estimated 7,073 people from 2017 to 2018, Chicago stands at just over 2.7 million residents.
The new estimates, released in Chicago late Wednesday, show that most municipalities in northeastern Illinois are not adding residents. Of the 279 incorporated towns and cities in Cook County, the collar counties and Kendall County, more than three-fourths lost population in the last year. The average municipality in the area shrank by 0.6%.
