About this feed

The Health Insurance Exchanges Monthly Effectuated Enrollment data provide select metrics on monthly effectuated enrollment across the Federally Facilitated Exchange (FFE) and State‑Based Exchanges on the Federal Platform (SBE‑FPs), which both use the federal enrollment platform (HealthCare.gov), as well as State‑Based Exchanges (SBEs) that operate their own eligibility and enrollment platforms.

These metrics include effectuated enrollment counts by state, exchange platform type, year and month.
