Examining Census 2010 ZIP Code Geographic Areas & Demographics
|
Census 2010 ZIP Code Tabulation Area (ZCTA) areas are approximate representations of USPS five-digit ZIP Code service areas.
ZCTAs are created using whole census blocks.
Scope & Use of ZCTAs. ZCTAs are defined by allocating each census block that contains addresses to a single ZCTA that reflects the most frequently occurring ZIP Code for the addresses within that tabulation block. Blocks that do not contain addresses but are completely surrounded by a single ZCTA are assigned to the surrounding ZCTA; those surrounded by multiple ZCTAs are added to a single ZCTA based on limited buffering performed between multiple ZCTAs. The ZCTA five-digit code represents the most frequently occurring USPS ZIP Code within that ZCTA. There are significant changes to the 2010 ZCTAs delineation from that used in Census 2000. For 2010 only legitimate five-digit areas are defined so there is no longer full national scope coverage. The 2010 ZCTAs better represent the actual Zip Code service areas because the Census Bureau initiated a process before creation of 2010 blocks to add block boundaries that split polygons with large numbers of addresses using different ZIP Codes. ZCTA Demographics. Using ZCTA boundaries, Proximity has developed ZCTA demographics by summarizing census block demographics to the ZCTA summary level. All census blocks in the U.S. are asssigned to ZCTAs.
