Four percent of the Illinois population is composed of illegal immigrants. This figure is from Illinois’ Undocumented Immigrant Population: A Summary of Recent Research, a report by the Illinois Coalition for Immigrant and Refugee Rights, which pegs the undocumented population in Illinois at 511,000. About 77 percent are from Mexico, but there are other countries of origin too, says author Fred Tsao.
