Where to Find Medicaid and CHIP Enrollment Data by State

Updated

The main entry point is the Enrollment & Operations Snapshot on Medicaid.gov, a monthly report with preliminary state-level Medicaid and CHIP eligibility operations and enrollment data. From the Medicaid.gov homepage, look for the "Enrollment & Operations Snapshot" heading and select "Get Report." If you want a shorter summary rather than the full dataset, check the "New & Notable" list for the latest monthly "Medicaid & CHIP Enrollment Data Highlights" item (for example, a June 2026 edition was posted). For program-wide performance measures rather than raw enrollment counts, the Medicaid & CHIP Scorecard is the companion resource.

What the Enrollment & Operations Snapshot contains

According to Medicaid.gov, the snapshot is a monthly data report covering preliminary state Medicaid and CHIP eligibility operations and enrollment data. Three words matter here:

  • Preliminary — figures can be revised in later releases, so cite the release month when you use them.
  • State-level — the report is organized so you can compare states, which is the usual reason people search for this data.
  • Eligibility operations plus enrollment — it covers both how eligibility determinations are running and how many people are enrolled, not enrollment alone.

How to get the data

  1. Go to medicaid.gov.
  2. Find the Enrollment & Operations Snapshot section on the homepage.
  3. Select Get Report to open the monthly report.
  4. Note the report month before pulling state figures, since the data is preliminary.
  5. For the most recent month's headline numbers, scan New & Notable for the latest "Medicaid & CHIP Enrollment Data Highlights" entry.

Expected result: a monthly, state-level dataset of eligibility operations and enrollment, plus a short highlights summary for the newest month.

Common sticking points

  • Treating preliminary numbers as final. Because the snapshot is explicitly preliminary, a state figure you quote today may differ from a later release. Always attach the report month.
  • Expecting one national total. The report is built around state eligibility operations and enrollment; if you need a single national figure, use the monthly highlights item instead.
  • Confusing it with policy pages. The homepage also features items such as Work Requirements Information and the Rural Health Transformation Program. Those explain rules and programs, not enrollment counts — the snapshot is the data page.

For state-level Medicaid and CHIP enrollment, start with the Enrollment & Operations Snapshot, use the monthly highlights for a quick read, and turn to the Scorecard when your question is about performance rather than counts.
