Did your town gain or lose? Check out the 2020 Census details for southwest Illinois
Results from the 2020 Census show which cities and villages across the metro-east either gained or lost population as compared to the previous census in 2010.
Five metro-east counties lost population in the 10-year period between 2010 and 2020 and one gained population, according to statistics released by the U.S. Census Bureau last week. Monroe County gained population while St. Clair, Madison, Clinton, Randolph and Washington counties lost population.
The Census Bureau has not yet posted 2020 population figures on its website for most metro-east towns but the BND has analyzed data released by the bureau to find the latest population figures for 93 cities and villages in six counties across southwestern Illinois.
There were increases in 35, losses in 57 and one place, St. Rose in Clinton County, remained the same at 1,422 people.
