Low-income people in states that haven’t expanded Medicaid are much more likely to forgo needed medical care than the poor in other states, according to a government report released Monday amid election debates from Georgia to Utah over coverage for the needy.

The nonpartisan Government Accountability Office worked with the National Center for Health Statistics to analyze federal survey data from 2016. The research focused on low-income adults ages 19-64 in states that did not expand Medicaid under the Obama-era Affordable Care Act, compared to their peers in states that did.
