This evaluation examines whether using information available to the U.S. Census Bureau, but not currently incorporated into the address list updating process, can improve the address list for future censuses and surveys. The Decennial Statistical Studies Division evaluated four topics that presented potential for improving address list maintenance activities:

Topic 1. Geocode Imputations
Topic 2. Administrative Records
Topic 3. Local Geographic Information Systems Coordinates
Topic 4. American Community Survey Time o f Interview Actions

The methodology to evaluate each topic included the 2010 Census Address Canvassing results and the final census status. Data from a supplemental field operation assisted in evaluating the geocode imputation topic . The address list refers to the Master Address File/Topologically Integrated Geographic Encoding and Referencing database. Extracts from the address list were used to obtain the 2010 Census Address Canvassing results . The final census status came from the Census Unedited File.
