California is a bellwether state for understanding the impact of the Affordable Care Act (ACA). Much attention has been paid to enrollment in California's new coverage options, such as the Medicaid expansion (Medi-Cal) and plans sold through ACA marketplaces (Covered California), and to changes in the uninsured from 2013 to 2014. However, less is known about how this coverage has affected people’s access to care and financial security, and why others remain uninsured. This report, based on the 2014 Kaiser Survey of Low-Income Americans aims to fill this gap by comparing the newly insured, previously insured and remaining uninsured across several of these important dimensions.
