More than half of Californians get their health insurance through private carriers. This infographic shows how the largest plans stack up in terms of enrollment and revenue.

April 2017

Health insurers covered more than 14 million Californians through group and individual policies in 2015. The interactive graphic below shows the breakdowns for health plans by regulatory body and type of coverage. This data visualization is a companion to California Health Insurers: Two Years After Reform, part of CHCF's California Health Care Almanac.
