Twice a year, CHIA updates its analysis of Massachusetts health insurance enrollment trends for the most recent trailing two-year period to give researchers and policymakers insight into the market. Approximately 6.4 million Massachusetts residents have health insurance coverage, where coverage is defined by unique Massachusetts residents with primary, medical membership in the 14 largest commercial payers, MassHealth (Medicaid), or Medicare.
The March 2020 edition, which covers the period between September 2017 and September 2019, includes an interactive dashboard, a detailed databook, and technical appendix.
Enrollment measures are also reported in CHIA’s Annual Report on the Performance of the Massachusetts Health Care System.
