From the Document: "We are pleased to be here today to discuss the operational status of the 2020 Decennial Census. After many years of research, planning, and testing, in January the U.S. Census Bureau (Bureau) kicked off the 2020 Census count of the population with the enumeration of remote Alaska, with Census Day (April 1) on the horizon. [...] At your request, our testimony today will describe the cost and progress of key 2020 Census operations critical to a cost-effective enumeration, as well as major trends or early warnings that may require Bureau or congressional attention to ensure a successful head count."
