With the 2020 census results out, many are eager to use the data—and to assess its accuracy. The U.S. Census Bureau has begun releasing its own data-quality evaluations, with national results from the 2020 Post-Enumeration Survey and the 2020 Demographic Analysis estimates. Data users outside the bureau are looking at quality, too. In this webinar, we’ll discuss this decade’s census data quality and how it compares with that of previous decades, what additional analyses are coming from inside and outside the bureau, and what questions remain.
