The Panel to Evaluate the Quality of the 2020 Census continues the Committee on National Statistics’ tradition of providing an independent, external review of the quality of the data collected in the 2020 Census and the component operations that produced those data. The need for this independent assessment is escalated by the nature of the 2020 Census: designed to implement several major changes to decades-old processes but confronting an unprecedented array of formidable logistical and operational challenges, including the forced delay in field operations due to the COVID-19 pandemic. The panel is expected to issue two reports.
