A good source of data would be to use the Tiger/Line Shapefiles: http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html There is a wealth of information here, and I hope it puts you on the right track. Thanks. Thoes are shapefiles. Do I need a map file, for example of Orange County? I know really little to this. Thanks
