Integrating information from local school district and community data sources is essential to understanding the relationships between them. A major problem in merging such data concerns the geographic incongruities of the boundaries of school districts (local education agencies) and the boundaries of communities. This paper focuses on resolution of this problem at the national and state levels. The recent attempt of the Southwest Regional Laboratory to resolve this problem through the Census Mapping project is described. It is evident that the near-optimal solution lies in a complete blocking of the United States and the identification of all the blocks in every school district to allow an accurate aggregation of Census data pertaining to each local education agency. The complexity of this effort has led the Census Bureau to develop and implement a digital cartographic database, the Typological Integrated Geographic Encoding and Referencing (TIGER) system. School district information from the states is being included. A lot of staff power is required to construct the database, and the district equivalency file will not be available until 1993. Great progress will be made if Congress passes a Uniform Data Act that requires a universal format for data from states receiving federal funds. Better forecasting and planning and more equitable distribution of funds will result when more timely and accurate data are available. There is a 14-item list of references. (SLD)
