An estimated 9 million children are now covered by the CHIP program across the U.S. In Missouri, more 624,000 children are covered by a combination of CHIP and Medicaid, though most children are covered by Medicaid. “CHIP has led to a substantial reduction in the uninsured rate for children, to the point where children now have only a 5 percent uninsured rate — the lowest ever,” said Tim McBride, professor at the Brown School and director of the Center for Health Economics and Policy. He also serves as chair of the oversight committee for Missouri’s Medicaid program called MOHealthNET.
