More than 47 million nonelderly Americans lacked health insurance in 2012, according to the Kaiser Family Foundation.
So who are they?
— Most are adults from low-income working families. Medicaid and Illinois' All Kids program provide free or low-cost coverage for virtually any child who lacks it.
— 38 percent live below the poverty level. For a family of four in 2012, that meant living on less than $23,050 a year.
— About 80 percent are U.S. citizens.
— 32.1 percent have not graduated from high school.
— Hispanics are less likely than the general population to have health insurance. In 2011, about 31 percent lacked health coverage.
