2020 Census

U.S. Census Bureau / U.S. Census Bureau

Each September, the U.S. Census Bureau releases the results of its annual American Community Survey (ACS). But, Mark Mather writes, due to the challenges posed by the COVID-19 pandemic in 2020, the Bureau has decided to forgo the standard data release and instead "release experimental estimates for a limited set of tables and geographic areas" in November.

"There were early warning signs that this was coming. In a presentation at our recent 2021 ACS Data Users Conference, Mark Asiala, an assistant division chief in charge of ACS statistical design, reported that between April and September 2020, the Census Bureau was forced to suspend many of its data collection operations, including in-person visits to homes that didn’t return survey questionnaires. He said the Census Bureau conducted one-third fewer interviews for the 2020 ACS, compared with the 2019 ACS."

The 2020 responses also experienced a significant level of "non-response bias," with respondents having "higher average incomes, education levels, and homeownership rates" on average than those who did not respond.

The lack of data deals a major blow to demographers who hoped to answer some essential questions about what happened to the U.S. population during the pandemic. "For states, metropolitan areas, congressional districts, and many large counties and cities, the 2020 ACS 1-year data could have provided our first comprehensive portrait of how American life changed during the pandemic."

"The good news is that 2021 ACS data should be released next year as planned. Because ACS data collection is ongoing, we will eventually be able to compare population and housing characteristics before, during, and after the pandemic."
