We have data covering all states of the U.S. that includes address
information for each observation in our file.  We want to determine a county
for each address in our data set.

Yes, our addresses include ZIP codes, and yes, I have located the zipcnty
SAS program kept at CIESIN (thanks to John Blodgett and Henk Meij).  But,
as John's explanatory memo points out, 13% of all ZIP code areas cross
county borders.  For addresses in those ZIP codes, we need a way to
determine a county knowing other address information (address, street or
road, place).  Where can I look for such information?


thanks,
