  5. ASPE’s Concerns About Differing Estimates of the Uninsured • Confusion of policymakers and the public • Potential methodological flaws • Appropriate differences, and what they can teach us • Research strategies for understanding factors driving differences

  6. NCHS Research Proposal to ASPE(1) Record Linkage Strategies • Analyze linked NHIS/MEPS files to compare: • Health insurance responses • Income measures • Link NHIS to Medicaid administrative records
