One thing to watch out for is that the Census doesn't use the official
USPS zip code boundary definition; they use what they call "Zip Code
Tabulation Areas." (working from memory so the definition of the
acronym may be slightly off) They are generally analogous to USPS zip
codes and accurate enough for many purposes, but they are "artificial"
zip code boundaries designed for fitting data organized by Census areal
units into non-Census zip code areal units.
