Since I only have Incorporated area feature class, how can I select census blocks that are in unincorporated area? Or not within any incorporated areas?

Thank you.

Select by Location, in Arcinfo, will give you a variety of options to refine that requirement.

Is there anyway to do it in ArcGIS 10 with ArcView level license? Thank you. –  user8517 Jun 28 '12 at 20:06
I believe that Select By Locatino is available in all licences of Arc. Have a look here for more details: help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//…. You can select all the ones that DO have their centers in an unincorporated area and then for the second part of your question, just switch selection. –  MappaGnosis Jun 28 '12 at 20:14
I did use select by location with "HAVE_THEIR_CENTER_IN" in Python. But I could not find a switch selection option after that. I really appreciate your help. –  user8517 Jun 28 '12 at 20:17
Open the attribute table of the feature class/layer with the selected features and click (should be) fourth button from the left to switch the selection. The selection modification options are generally found within the attribute table. –  AHigh Jun 28 '12 at 20:58
If you're doing it in Python simply add a line under your SelectLayerByLocation() that goes something like this: SelectLayerByAttribute("LayerWithSelections","SWITCH_SELECTION") help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/… –  AHigh Jun 28 '12 at 21:46

Give this a shot:

arcpy.env.workspace = "c:\\yourWorkspace"
