Pathways to coverage: the changing roles of public and private sources.

Using data from the Medical Expenditure Panel Surveys for 1997 and 2005, spanning the eight-year period after enactment of the State Children's Health Insurance Program (SCHIP), we examine whether the composition of insurance coverage has changed for working families. Public coverage has played an increasingly important role for working families with children. For families without access to job-based insurance, roughly two-thirds of single-parent and over half of two-parent families with children had at least one family member covered by public insurance in 2005. Among families with access to job-based insurance, nearly half of minority single-parent families had at least one family member with public coverage.
