Rick Ayers from ESRI sent me the attached note (inst.doc) that explains how to download
redistricting data at the geographic detail of County - census blocks from the ESRI
. For those who want to convert Census data into ESRI shapefiles,
I think the method Rick describes is easier to use than the one I wrote down to this
listserve a while ago.
Claritas Inc. is also making Census data available for free downloads from their website
