Order Code 96-979Updated September 5, 2008Health Insurance: Uninsured by State, 2005-2007Chris L. Peterson and April GradyDomestic Social Policy DivisionSummaryBased on data from the Census Bureaus Current Population Survey (CPS), anestimated 45.7 million people lacked health insurance coverage in 2007, representing15.3% of the civilian noninstitutionalized U.S. population.When comparing state-level health insurance estimates, a three-year average is usedto increase their reliability. During 2005-2007, the estimated average percentageuninsured was 15.5% nationally, ranging from a low of 8.3% in Massachusetts to a highof 24.5% in Texas. States in the Midwest and Northeast generally had lower uninsuredrates than those in the South and West.These state-level estimates must be interpreted with caution because they are basedon a sample of the population. When sampling variation is taken into account, theuninsured rate in nine states is not statistically different from the national rate. Theuninsured rate in 28 states and the District of Columbia is statistically lower than thenational rate, and statistically higher in the remaining 13 states.Estimates of Health Insurance Coverage, by St
