The 2010 Decennial Census has a number of challenges, incl. weaknesses in managing IT, operational planning, and cost estimating, as well as uncertainty over dress rehearsal plans and the ultimate cost of the census. In 2007, the Census Bureau (CB) conducted the address canvassing operation -- the final time to test handheld computers (HHC) that will be deployed during the Census. The CB also announced that the HHC was likely to incur significant cost overruns and announced a redesigning effort to get the Census back on track. This report: (1) analyzes CB and contractor data showing how HHCs operated and its implications on operations; and (2) examines implications the redesign may have on plans for address canvassing in the 2010 Census.
