About RAS

Research Advisory Services specializes in the analysis of data about geographic areas – Census blocks and tracts, Zip Codes®, voting precincts, land parcels, and traffic analysis zones.  To manage and analyze very large files of data about thousands of small areas, RAS relies on geographic information system (GIS) software and database management programs.
