Here are the data sources for the three charts presented for each department:

  • Spending in Constant Dollars. These figures are calculated from data in the Budget of the U.S. Government, Fiscal Year 2013.
  • Shares of Spending by Type of Activity. Aside from interest, all federal spending falls into one of four categories: employee wages and benefits, purchases or procurement, aid to the states, and subsidies or benefits paid to individuals, businesses, and nonprofit groups. Data in the pie charts are rough estimates based on budget data measured in “outlays” and other budget data measured in “obligations.” Spending on employee pay, purchases, and benefits by department are available in the Budget of the U.S. Government, Fiscal Year 2013, Federal Spending by Object Class.
