Note:	1. Some columns in spreadsheet may need to be adjusted smaller to view data on screen.
	2. These Census 2010 Zip Code Tabulation Areas (ZCTAs) are different than the U.S. Postal Service Zip Code delivery area. There will not be a match between the two Zip Code areas. Later this year, we will obtain the geographic boundaries for the ZCTAs.
