Relating Census Tracts & ZIP Code Areas
Contents
This section illustrates use of the GeoGateway tool to develop a map showing a Census 2010 census tracts layer and a ZIP Codes layer focused on one county. The same process may be applied to any county in the U.S. using the CV XE Viewer and all Levels. The same process can be applied at the state level (all tracts in the state and all ZIP Codes in the state).
See corresponding interactive table relating all tracts to all ZIP codes -- http://proximityone.com/ziptractequiv.htm
