Geographic Area Description
A ZIP Code tabulation
area (ZCTA) is a statistical geographic entity that approximates the
delivery area for a U.S. Postal Service five-digit or three-digit ZIP
Code. ZCTAs are aggregations of census blocks that have the same predominant
ZIP Code associated with the addresses in the U.S. Census Bureau's Master
Address File (MAF). Three-digit ZCTA codes are applied to large contiguous
areas for which the U.S. Census Bureau does not have five-digit ZIP
Code information in its MAF. ZCTAs do not precisely depict ZIP Code
delivery areas, and do not include all ZIP Codes used for mail delivery.
The U.S. Census Bureau has established ZCTAs as a new geographic entity
similar to, but replacing, data tabulations for ZIP Codes undertaken
in conjunction with the 1990 and earlier censuses.
