Abstract:	This paper provides background on the issue of missing information in the census and the long-standing use of the traditional hot-deck methodology. It discusses the emergence of a major interdivisional project to examine alternative methodologies, including the use of administrative records and spatial modeling. It also briefly discusses direct improvements to the traditional hot-deck method. The paper provides the research's objective, scope, and methodology. An overview of the methods is provided in addition to rationale for the approaches taken and the challenges we faced, including lack of "truth," public acceptability, possible legal issues, and operational feasibility. Finally, the paper discusses the development of the hybrid approach that seeks to optimize the strengths of different methods.
