The 2005-2007 SAHIE estimates utilized the Annual Social and Economic Supplement (ASEC) of the Current Population Survey (CPS) to model health insurance coverage. See methodology for additional information. The estimates were produced for either 200% or 250% of the income-to-poverty ratio (IPR) depending upon the state's implementation of the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) guidelines.
