The Children's Health Insurance Program (CHIP) is one of a number of federally financed programs that provide benefits to low-income working families in the greater Washington area. The program was enacted October 1, 1997, as Title XXI of the Social Security Act. By October 1998, the program was implemented throughout the greater Washington area. During its first year of operation in Washington, D.C. and the surrounding areas, the program provided health insurance to more than 13,000 previously uninsured children.
