Source of data: IECAM demographers prepared estimates of population based on Census Bureau estimates for the following programs or surveys:

  • Population Estimates Program v2010
  • American Community Survey 1-year
  • American Community Survey 3-year
  • American Community Survey 5-year

These data are available for the following geographic areas: state, county, township, IL state senate district, IL state house district, US Congressional district, Elementary School District, Unit School District (and by ISBE region and IDHS region, which are sums of counties)

Note: For the “total number of persons” for the population demographics, the sum of the population for Chicago and the population for Non-Chicago Cook County may exceed the total population of Cook County because there are some residents of Chicago who live in DuPage County. The City of Chicago contains a small portion of northeast DuPage County.
