ProximityOne ZIP Code Block Areas 2010 ProximityOne ZIP Code Block Areas 2010 (ZCBA2010) geographic areas provide current approximations to U.S. Postal Service (USPS) 5-digit ZIP code areas. ZCBAs are updated annually. ZCBAs reflect current USPS ZIP Code boundaries and are comprised of census block boundaries. The ZCBA2010 areas may be conceptually thought of as updates to the Census Bureau ZCTA introduced with Census 2000. ZCTAs have been developed to overcome the difficulties in precisely defining the land area covered by U.S. Postal Service ZIP Codes and enable partitioning/analysis of ZIP Code areas by census block. ZCTA boundaries have not been updated since 2002. ZCBAs are groups of contiguous census blocks that provide generalized area representations of USPS ZIP Code service areas. Each ZCBA is built by aggregating the census blocks whose addresses correspond to a specific ZIP Code. ZCBAs represent the majority USPS five-digit ZIP Code found in a given area. For those areas where it is difficult to determine the prevailing five-digit ZIP Code, the higher-level three-digit ZIP Code is used for the ZCBA code. ZCBA Vintages and Updates. ProximityOne ZIP Code Block Areas 2010 (ZCBA2010) have been developed using a 2010 vintage 40+ million USPS carrier route dataset. The ZCBA2010 has no relationship to Census 2010. The ZCBA2010 geography makes use of Census 2000 census block boundaries. Update Schedule (monthly updates optionally available): • ZCBA2011 ... mid-2011 using Census 2010 census block boundaries. • ZCBA2011 data use mid-2011 vintage USPS carrier routes. • ZCBA2012 ... mid-2012 using Census 2010 census block boundaries. • ZCBA2012 data use mid-2012 vintage USPS carrier routes. Contact Proximity (888-364-7656) for more information about using the ZCBA shapefiles and related equivalence and demographic data. 5-Digit ZIP Demographic Profile Database The 5-Digit ZIP (ZIP Code Tabulation Area) Demographic Profile Database is comprised of 4 dbase structured files. This set of files contains the most widely used set of approximately 550 subject matter items derived from Census 2000 summary files. The database consists of four subject matter files containing data as organized and described in the following links. • DP-1 General Demographics • DP-2 Social Characteristics • DP-3 Economic Characteristics • DP-4 Housing Characteristics A sample display of the data may be accessed at http://proximityone.com/p1zip.htm.

5-Digit ZIP Code Extended Demographics Dataset The 5-Digit ZIP Code (ZIP Code Tabulation Area) Code Extended Demographics Data File is a dBase structured file that contains the Census 2000 subject matter fields as described at http://proximityone.com/dp2000et.htm (DP-1 items). Data in the extended demographics file may be used to develop profiles such as this example for ZIP Code 77027 in Houston, TX (PDF). Click here to purchase:
5-Digit ZIP Code Age-Race-Sex Demographics Dataset The 5-Digit ZIP Code (ZIP Code Tabulation Area) Age-Race-Sex Demographics Dataset is a dBase structured file that contains the Census 2000 data for these categories: Male population Female population Population by age for these age ranges: 0-10 years 11-17 years 18-29 years 30-39 years 40-49 years 50-59 years 60-64 years 65-74 years 75 years and over for each of these race/ethnic categories: Not Hispanic White Black AIAN API Other 2+ Races Hispanic Click here to purchase:
ZIP-Census Block Demographics and Equivalency File [goto top] The ZIP-Census Block Demographics and Equivalency File enables a user to determine the set of Census 2000 census blocks that comprise a ZIP Code (ZIP Code Tabulation Area) area. The ZIP-Census Block Demographics and Equivalency File contains a record for each unique combination of a ZIP code area and census block (8.2 million geographic areas) Each record provides geographic area measurements, latitude-longitude, and the same set of demographic data fields (DP-1 items for each census block) as contained in the Extended Demographics file.

ZIP-County-MSA (ZCM) Equivalency File The ZCM Equivalency File enables a user to determine the county(s) and metropolitan area in which the ZIP Code (ZIP Code Tabulation Area) area is located. ZIP Code tabulation areas almost always exist within a single state but are independent of all other statistical and governmental entities except Census 2000 tabulation block. 27 percent of ZIP Code tabulation areas cross county or county equivalent boundaries nationwide. There are 47,010 unique ZIP Code tabulation areas-county combinations (32,038 are five-digit ZIP Code tabulation areas). The ZCM equivalency file contains 47,010 records. Of these five-digit ZIP Code tabulation areas, 42 cross state boundaries. Click here to purchase:
5-Digit ZIP Code (ZCTA) Map Files (Shapefiles) Proximity provides ZCTA 5-digit boundary files in shapefile format for use with popular mapping software and GIS applications. The U.S. 5-digit ZIP Code (ZCTA) map file is in shapefile format and may be used to display maps showing relationships of ZIP code areas to other geography, demographic, economic or business patterns, and to perform visual queries and geospatial analysis.
