Illinois Medicaid

Medicaid, together with CHIP and AllKids, provides services to some 3.2 million people.

Nearly a million Illinois residents have gained health insurance since the ACA opened for business in October 2013 – the vast majority of them through the expanded Medicaid program.

Illinois' AllKids program provides healthcare coverage to about 71% of Illinois children in families with low to modest income – and over 40% of all the state's children.

Illinois Medicaid


Medicaid beneficiaries represent about a quarter of Illinois' residents, with children accounting for nearly half of the total. Enrollment rates vary considerably across the state's 102 counties.

ACA Expansion

Illinois' Medicaid expansion has been responsible for the largest share of the decline in uninsurance since ACA enactment. Medicaid covered 1.3 million working-age residents (17.5%) in 2016, up from 864,000 in 2012 (13.2%), a 49% increase.
