The DOD has responded to the NEPA EIS requirement in many ways. The socioeconomic impact of projected federal actions has been predicted through the CERL EIFS model, which is based on county level information from within a 30 mile radius of the installation with a proposed change. The purpose of the study was to investigate the possibility of basing the model on census tract information. Rules were established for assigning census tracts to zip code areas. The zip code areas were used because they most accurately and conveniently depicted where the base personnel live. Thus, areas actually affected by base mission changes were examined. The rules proved to be valid. Subsequently assignment and environmental impact assessments were run to determine if differences existed between results gained from census tract and county based data. The differences were difficult to detect because of the need to specify a multiplier for each area of assessment. All indications support intuition that the results are different for the two data basis and more practical for the user.
