the following passage:
"The term ZCTA was created to differentiate between this entity and true USPS
ZIP Codes.
ZCTA is a trademark of the U.S. Census Bureau; ZIP Code is a trademark of the U.S.
Postal Service."
Therefore, ZCTA information _approximates_ ZIP information for census purposes.
If you want to map/use ZIP code information, don't use the ZCTA information to
do it, I would infer.--ceyockey
any area-oriented representation of zip data will be an approximation.
it's the nature of the beast.
