The application of computer programing to construction of maps and geographic distributions of data has been called geocoding. This new use of the computer allows much more rapid analysis of various demographic characteristics. In particular, this paper describes the use of computer geocoding in the development of a plot of student density in Milwaukee, where school boundaries were being redrawn. The objective of redistricting was to solve school overcrowding and identify possible future boundaries for smaller school districts. The computer produced location grids which, when superimposed on conventional maps, allowed analysis of the school population on several variables, and hence more efficient redistricting. Such geocoding could have many possible applications in the study of other school demographic problems, such as the distribution of minority groups. (RB)
