This collection contains expenditure data for the 150 largest United States federal government programs, which make up close to 90 percent of total federal spending. The source of information on federal funding activity is the GEOGRAPHIC DISTRIBUTION OF FEDERAL FUNDS (GDFF) series, published annually from 1968-1980 by the Federal Information Exchange System, a component of the Community Services Administration (CSA). The files released here have been further processed by the Intergovernmental Fiscal Analysis Project (at the University of Michigan) and the Inter-university Consortium for Political and Social Research (ICPSR), as part of an effort to develop a comprehensive database for monitoring and analyzing the distribution of federal funding in the United States. The files differ not only by units of analysis, but also by what the variables measure. There are three kinds of variables: (1) dollar amount of program expenditures, (2) amount expended per capita, and (3) percent of total federal funds spent on programs in geographic areas. In Part 1, Expenditures by State, the geographic region is the unit of analysis, and data cover the 50 states, the District of Columbia, census regions and divisions, and the nation as a whole. The variables are dollar amounts rounded off to thousands for each of 150 programs measured at 11 time points (10 years plus a transition quarter). In Part 2, Per Capita Expenditures by State, per capita expenditures (rounded off to thousands) for the top 150 federal programs are measured at 11 time points. For Part 3, Percent Concentration of Expenditures by State, percent concentration figures (which are equivalent to state share of total national program expenditures for the top 150 programs) are measured at 11 time points. In Part 4, Dollar Expenditures by State by Year, the record units are geographic units (the 50 states, the District of Columbia, and census regions) by time point. This file contains dollar expenditures (rounded off to thousands) for the top 150 programs. For Part 5, Per Capita by State by Year, the variables are per capita expenditures rounded off to thousands. In Part 6, Percent Concentration by State by Year, the variables are percent concentration figures (equivalent to state shares of total national program expenditures). In Part 7, Dollar Expenditures (Unit Is Program) for Each State by Year, the federal program is the unit of analysis and variables describe program characteristics, including type of recipient, House committee jurisdiction, hard dollars vs. soft dollars, appropriation account number, program name, type of assistance, and type of recipient. The remaining variables describe the program expenditures for each of 11 time points for 66 geographic units. For Part 8, Per Capita Expenditures (Unit Is Program) for Each State by Year, variables include per capita expenditures on the program for the 66 geographic units measured at 11 time points. For Part 9, Percent Concentration (Unit Is Program) for Each State by Year, variables include percent concentration of expenditures (share of the total federal expenditure for the geographic unit) for 66 states/regions for 11 time points.
