- We calculated the size of each market from 2015 through 2022 using covered life-years that issuers reported to Centers for Medicare & Medicaid Services or states. This measure is calculated as the average number of lives insured each month in the reporting year. Rather than a point-in-time measurement, this measure accounts for changes in enrollment that occur throughout the year.
- Covered life-years is one of several ways to measure health insurance enrollment, so it may differ from other measures of market size.
- We rounded market share values of less than 0.5 percent to zero.
