Hi, is IMPLAN online using USPS zip codes or “Zip Code Tabulation Areas” from the Census? Many thanks.

  Hello, We use USPS ZIP Codes. The data actually comes mostly from the Bureau of Census County Business Patterns (CBP). You can find [url=http://www.implan.com/index.php?option=com_content&view=article&id=306&Itemid=1797 ]more information here[/url]. Also, there are instances where some USPS ZIP Codes that aren't in the IMPLAN dataset. Please see [url=http://www.implan.com/index.php?option=com_content&view=article&id=307&Itemid=1797#zip-codes-not-represented]more info here[/url]. Our raw data usually are collected and reported according to ZCTAs, which generally map 1:1, but not always perfectly, with USPS zip codes. Sometimes, though, the data are reported by a zip code that might be for a particular PO box, which isn't really a ZCTA, but there are data for the po box, and we usually find the county-mapping for that po box according to USPS. Please let us know if you have additional questions. IMPLAN Group Staff
