I know that zip code boundary files are not in the public domain, but
they just keep asking...  Has anyone ever seen the area (as in sq. miles)
of zip codes?  Five digit would be fine now, but you know he'll be back for
+4.  This is for a population density question and the user has been advised
that zips are not an appropriate statistical area...
 
Thanks in advance.
