The U.S. Census Bureau was required to use a revised methodology for the release of 2016 – 2020 American Community Survey data to account for a low response rate and non-response bias caused by COVID-19 pandemic disruptions.

The American Community Survey was founded before the 2010 Census and released its first set of multi-year estimates in 2008. It replaced the decennial Census long form to provide more timely statistics, rather than waiting every 10 years.

The survey contacts 3.5 million addresses annually covering 40+ topics and creating 1,140 detailed tables, 83 subject tables, five comparison profiles, narrative profiles and multiple online Census tools. The survey data is used to help allocate more than $675 billion in federal funds.
