Abstract:

In Census 2000, the U.S. Census Bureau began using Optical Character Recognition to capture the names on questionnaires. As a result, it is now possible to check for duplicate people after the questionnaires are processed. However, there are challenges to removing duplicates from final Census counts. Duplicated persons occur as a result of: persons listed on more than one questionnaire for reasons such as part-time residency, and housing frame duplication. In the former, it is not known from the questionnaires which residence is correct. In the case of housing duplication, resolution is complicated by the similar situation of duplication of persons resulting from apartment mix-ups. The Census 2010 plan is for a general coverage operation following enumeration to resolve identified coverage cases. In this paper we present an overview of our unduplication plans for the 2010 census.
