Maps can be created with SAS® by using either SAS/GIS® or the GMAP procedure (PROC), one of the procedures available within SAS/GRAPH. This paper shows you how to use the GMAP procedure, not SAS/GIS. Four different map types can be created using GMAP: choropleth, prism, surface, and block.

How is a choropleth map created in SAS?

Choropleth maps are produced by using a combination of a map data set and a response data set. A map data set contains the information needed to draw map boundaries, e.g. countries, states, counties, zip codes, etc. A response data set contains the information that is to be displayed on the map, e.g. population, birth rates, death rates, etc.
