Boundary Data

Administrative and Statute boundary data is derived from the National Map (also know as 'the Prime 2' database) and supplied as attributed polygon structures which may be incorporated into Geographical Information Systems (GIS). These products are suitable for use as a powerful demographic analysis tool, particularly in conjunction with census data.
