Experts estimate that one-half to two-thirds of California's 7.3 million uninsured could be covered under the 2010 Affordable Care Act. While details of how this population will be covered are still being worked out, CHCF offers a brief look at the current health insurance market. These interactive graphics provide a breakdown of enrollment in commercial plans and public programs, as well as a visual guide to the consolidation of health plans since 1985. A timeline also marks key milestones in the history of health insurance in California, from the opening of the first prepaid group practice of physicians in Los Angeles, to the historic passage of national health reform in 2010.

The three graphics are provided through the links below.
