Community health centers (CHCs) are in a strong position to meaningfully contribute to health promotion, early detection, and improvement in health care outcomes for some of the most vulnerable person in the nation, since almost one in three users of federally funded CHCs was uninsured in 1994. The purpose of this article is to compare uninsured CHC users with uninsured people nationwide. Data for the analysis came primarily from two population-based surveys: the 1994 National Health Interview Survey (NHIS) and the 1995 Community Health Center (CHC) User Survey.
