Medicaid and State Children’s Health Insurance Program (CHIP) data are dispersed across a wide variety of sources and often difficult to find. MACPAC brings together the most up-to-date Medicaid and CHIP data into one source, MACStats, which are published annually in the MACStats: Medicaid and CHIP Data Book, and updated periodically throughout the year on macpac.gov. This presentation provides highlights and key points from the 2017 edition of the MACStats data book.
