Medicaid enrollment data updated monthly by KFF tracker

KFF publishes a monthly tracker presenting the latest data on Medicaid and Children’s Health Insurance Program (CHIP) enrollment, according to their October 2026 report.

The enrollment data come from the Centers for Medicare & Medicaid Services (CMS) as part of the Performance Indicator Project, providing insights into both children and adult enrollees.

The tracker focuses on full-benefit enrollees and excludes individuals receiving limited benefits, such as family planning services only, meaning it does not represent the total Medicaid population.

This data is useful for analyzing trends in Medicaid enrollment over time and supports health policy research and public understanding of the health care system.

KFF’s role includes conducting original public opinion and survey research to inform national debates on health policy, with this tracker being a key resource for current enrollment statistics.
