Census Bureau to Host Webinar on Release of American Community Survey 1-Year Experimental Data

Press Release Number CB21-187


The U.S. Census Bureau has announced a webinar to explain and answer questions about the release of estimates from the 2020 American Community Survey (ACS) 1-year data using experimental weights. The ACS is one of the most comprehensive sources of information about the U.S. population, providing key demographic, social, economic and housing statistics. The COVID-19 pandemic significantly disrupted the ability to reach people and limited their ability to participate in the 2020 ACS. Therefore, the Census Bureau will release experimental data instead of the standard 1-year data products.

The webinar will examine all 2020 ACS 1-year experimental data products also released Nov. 30, including:

  • Experimental data tables.
  • Technical working paper: “Addressing Nonresponse Bias in the American Community Survey During the Pandemic Using Administrative Data.”
  • 1-Year Public Use Microdata Sample (PUMS) File with experimental weights.
  • Blog: “An Overview of Addressing Nonresponse Bias in the American Community Survey During the Pandemic Using Administrative Data.”


Tuesday, Nov. 30, at 2 p.m. EST 


Donna M. Daily, chief, American Community Survey Office, U.S. Census Bureau 

Jonathan Eggleston, senior economist, Center for Economic Studies, U.S. Census Bureau
