About this dataset
This data set presents annual enrollment counts of Medicaid and CHIP beneficiaries by program type (Medicaid or CHIP). Three metrics are presented: (1) the number of beneficiaries ever enrolled in each group over the year (duplicated count); (2) the number of beneficiaries enrolled as of an individual's last month of enrollment (unduplicated count); and (3) average monthly enrollment in each group.
