Last week, the U.S. Census Bureau released 2011 population estimates for all metropolitan statistical areas (MSAs) and counties; these are the first estimates released since the 2010 Census.
- Between 2010 and 2011, the Chicago MSA grew by an estimated 32,169 people (0.3%) to 9,504,753 total residents; this ranks it 18th nationally for total growth and 233rd for percent growth (of 366 MSAs). Minneapolis-St. Paul was the only Midwestern MSA to add more residents than the Chicago region (by 404 people, 32,573 added total), and the Detroit and Cleveland MSAs lost the most nationwide (-4,890 and -7,257, respectively).
- Within the Chicago MSA, Cook County added the most total residents (17,109), while Kendall County grew by the largest percentage (1.2%).
