From "CBO’s Analysis of the Major Health Care Legislation Enacted in March 2010" by Douglas W. Elmendorf, CBO Director, March 30, 2011, Statement before the Subcommittee on Health, Committee on Energy and Commerce, U.S. House of Representatives:

About 23 million nonelderly residents will remain uninsured: About one-third of that group will be unauthorized immigrants, who are not eligible to participate in Medicaid or the insurance exchanges; another quarter will be eligible for Medicaid but are not expected to enroll; and the remaining fraction will include individuals who are ineligible for subsidies, are exempt from the individual mandate, choose not to comply with the mandate, or have some combination of those characteristics.
