Report: Illinois’ Undocumented Immigrant Population

February 04, 2014

The Illinois Coalition for Immigrant and Refugee Rights (ICIRR) is releasing a new report, “Illinois’ Undocumented Immigrant Population.”  This report summarizes demographic research by Rob Paral and Associates regarding the geographic distribution and major characteristics of our state’s undocumented immigrants. Among the major findings:


·         Of Illinois’ 511,000 undocumented immigrants, 60% reside in the Chicago suburbs, with large concentrations in Kane, Lake, and DuPage Counties as well as suburban Cook County.


·         Three out of every five undocumented immigrants is between the ages of 25 and 44.


·         Undocumented immigrants live overwhelmingly in family households, most of which also include U.S. citizen relatives.


·         Illinois’ undocumented immigrants participate in the state labor force at high rates, working in a broad range of industries and occupations.


The report also discusses the implications of these findings for immigration reform. The full report is available here. For more information, please contact Fred Tsao at 312 332-7360 x213 or ftsao[at]


This report is made possible through the generous support of the Polk Bros. Foundation, John D. and Catherine T. MacArthur Foundation, the Illinois Funders DACA Relief Initiative, and the Chicago Community Trust.
