*Health insurance enrollment refers to fully insured plus self-insured medical enrollment for health insurance companies-- companies that offer fully insured products. Does not include specialty benefits (dental, etc.)

**Managed care penetration rate calculated as a percentage of state population per U.S. Census Bureau estimates. Managed care penetration is calculated as the number of enrollees reported at the state level for health plans that are able to provide a geographic breakdown. State-by-state breakdown of enrollment was not available from all plans. Partial state breakdowns are used where only part of the total plan enrollment can be attributed to a specific state. Enrollment may be counted by the state in which each member resides, OR all members may be counted by the location of the employer/group health client/ plan sponsor. This can result in a managed care penetration of greater than 100% in a particular state.
