Of the 3.7 million people who could lose coverage, most are low-income earners, young adults, part-time workers, or people of color.

Nearly 10% of California residents have gained insurance coverage under Medicaid expansion, and 3.7 million residents could lose coverage if Medicaid expansion is reversed under a repeal of the Affordable Care Act, according to a recent study.

The impact of an ACA repeal would vary by county, because some counties have benefited more than others under Medicaid expansion, stated researchers in the study, titled ACA Repeal in California: Who Stands to Lose?

A reversal of Medicaid expansion would disproportionately impact low-income earners, young adults, part-time workers, and people of color, according to the study, which was conducted by the University of California Berkeley Center for Labor Research and Education and the UCLA Center for Health Policy Research.
