Coverage Trends
With the implementation of the Affordable Care Act (ACA), the health insurance landscape changed dramatically in California. Fewer Californians are uninsured, more than one in three is now enrolled in Medi-Cal, and over a million purchase insurance through the ACA-mandated health insurance marketplace, Covered California. CHCF reports analyze and track trends in health insurance coverage, how much that coverage costs, and who remains uninsured.

Coverage Trends
Millions of Californians lost jobs during the COVID-19 pandemic. But early information from California’s insurance regulators suggests that — at least through June — the number of Californians with job-based health insurance has not changed as dramatically as feared.
