Synopsis of Mini-workshop
ACS data are noisy http://www.psc.isr.umich.edu/dis/acs/aggregator/
ArcGIS extension http://gesg.gmu.edu/census/index.htm Tool that allows one to map geographic variation in a
characteristic & show data quality or test for differences
ArcGIS Or do by hand via layers

Purpose of ArcGIS Extension
Mapping ACS Estimates with CV
Identifying Areas with Significant Differences Selected unit vs all other Several units vs all other Fixed value with all

ArcGIS Extension
Invoke ArcGIS
Everything happens within ACS Mapping Tool Join shapefile & data table Choose procedure
Need to save as layer package To modify symbology, etc.
