2020 Census Operational Adjustments Due to COVID-19

We adapted or delayed some of our operations to protect the health and safety of our staff and the public and make sure we get the same population counted another way.

Share:

In light of the COVID-19 outbreak, the U.S. Census Bureau adjusted 2020 Census operations in order to:

  • Protect the health and safety of the American public and Census Bureau employees.
  • Implement guidance from Federal, State, and local authorities regarding COVID-19.
  • Ensure a complete and accurate count of all communities.
