IF YOU DRILL down below the federal subfunction level you can see federal spending at the agency code level. This spending information is obtained from Outlays, an Excel spreadsheet (4.5MB) that contains federal spending numbers classified by department, bureau, and agency code for FY 1962 through FY 2008. There are about 4,000 line items at the agency code level. The file can be downloaded from Budget of the United States Government: Public Budget Database Fiscal Year 2008 in xls, csv, or zip format. Only spending line items in excess of $0.05 billion are displayed atusgovernmentspending.com.
