This report provides results from the 2010 Census Evaluation of Address Frame Accuracy and Quality. The Decennial Statistical Studies Division conducted this evaluation as part of the 2010 Census Program for Evaluations and Experiments to evaluate the accuracy of the address frame after the 2010 Census Address Canvassing operation and after completion of all 2010 Census operations. Specifically, this evaluation used results from the 2010 Census Coverage Measurement operation and a special supplemental field operation to estimate the number and percent of housing units correctly added (and added-in-error) and correctly deleted (and deleted-in-error) by census operations. In addition, this evaluation examine d the universe of addresses coded as “missing” from the census by the Census Coverage Measurement operation to determine if the census included them as valid housing units, but incorrectly geocoded them to a 2010 Census collection block outside of the Census Coverage Measurement geographic search area. This geocoding error analysis included a second supplemental field operation.

This evaluation was based on two Census 2000 studies:

1. “Analysis of Deleted and Added Housing Units in Census 2000 Measured by the Accuracy and Coverage Evaluation” (Smith et al . , 2003), and
   
   
2. “An Assessment of Addresses on the Master Address File ‘Missing’ in the Census or Geocoded to the Wrong Collection Block” (Ruhnke, 2003).

This evaluation expand s on the work conducted by Smith et al. (2003) by including a component to estimate the number and percent of addresses that the 2010 Census Address Canvassing operation correctly added (and added-in-error) and correctly deleted ( and deleted-in-error) . The Smith et al. evaluation (2003) did not produce similar estimates for either Census 2000 Block Canvassing or Census 2000 Address Listing.
