Yesterday, the Centers for Medicare & Medicaid released several important data-heavy reports, featuring a lot of month-by-month, state-by-state and year-by-year ACA enrollment data. There's a lot of data to dig into, so I'm breaking this into several posts.

First up: Average monthly effectuated enrollments. It's important to understand the difference between someone selecting a Qualified Health Plan (QHP) from one of the ACA exchanges during the Open Enrollment Period and someone actually being enrolled in an effectuated policy...that is, just because you sign your family up for a policy on HealthCare.Gov (or a state-based exchange), you aren't considered effectuated until you actually pay for the policy.
