Documentation and methodology
Underlying data are from the Congressional Budget Office Average Federal Taxes by Income Group, “Average Federal Tax Rates for All Households, by Comprehensive Household Income Quintile, 1979–2007,” “Sources of Income for All Households, by Household Income Category 1979 to 2007” [Excel spreadsheets] and unpublished data related to the same report on the composition of in-kind income, with a breakout for health spending (both government transfers and employer-sponsored insurance benefits). The tax rate is taken directly from the first Excel spreadsheet cited here, while the transfer rate is calculated as the share of cash transfers and Medicare and Medicaid spending in comprehensive income.
