Since 1790, the U.S. census has been a recurring, essential civic ceremony in which everyone counts; it reaffirms a commitment to equality among all, as political representation is explicitly tied to population counts. Assessing the 2020 Census looks at the quality of the 2020 Census and its constituent operations, drawing appropriate comparisons with prior censuses. The report acknowledges the extraordinary challenges the Census Bureau faced in conducting the census and provides guidance as it plans for the 2030 Census. In addition, the report encourages research and development as the goals and designs for the 2030 Census are developed, urging the Census Bureau to establish a true partnership with census data users and government partners at the state, local, tribal, and federal levels.
