Description:
The release of U.S. decennial census data has traditionally offered geographers a great opportunity to update our understanding of unfolding trends in American population and housing. Some exceptional circumstances have, however, diminished the utility of new 2020 census data to an extent that is not yet well understood. First, various conditions--most dramatically the COVID-19 pandemic--posed significant challenges for completing an accurate count in 2020. Second, an effort by the Census Bureau to modernize its privacy protections has added substantial noise and uncertainty to 2020 small-area data, and to implement the new protections, many tables have either been postponed or dropped from publication plans altogether.
Still, the first release of 2020 census data in August 2021 provides a bevy of information for areas large and small across the country, and additional releases scheduled for 2022 will provide much more. The Bureau also released in August an important new version of "demonstration" 2010 census data, generated by applying the 2020 privacy protection system to 2010 data, which enables a thorough assessment of the effects of the new system on data quality.
