From the Document: "Today, we are issuing the first in a series of planned reports that will assess the operations of the 2020 Census and identify lessons learned as planning begins for 2030. My statement today is based on that report entitled, '2020 Census: Census Bureau Needs to Assess Data Quality Concerns Stemming from Recent Design Changes'. The report describes the key changes that the Bureau made in response to the COVID-19 [coronavirus disease 2019] outbreak and how those changes affect the quality of the census. For that work, we reviewed Bureau decision memos and planning documents. We also reviewed Bureau announcements related to the COVID-19 response and any characterizations of the resulting operational changes."
