Data analysis and graphics software for micro computers and main frames include components that will easily draw maps to the users' specifications. These components make it possible to apply data to a geographic base and to shade the map as desired. One of the major problems with computer mapping is the choice of geographic unit of aggregation and how information for local health policy and planning can be diluted and misleading by using geographically aggregated health statistics that are more appropriate for state and federal decision making. A study demonstrates the effects of choices of aggregation. Current developments affecting local policy and planning include geographic information system software designed to generate, analyze, and display mapped data.
