The 2020 Census was a massive undertaking. It required counting a diverse and growing population in the United States. To do this, the U.S. Census Bureau:
There are three ways that the Census Bureau initially collected responses from people for the 2020 Census: online, by phone, and by mail.
Between March 12-20, most households received an invitation to participate in the 2020 Census. Once the invitation arrived, people could respond online, by phone, or by mail.
The Census Bureau then followed up—in person or over the phone—with homes that did not respond to the census on their own.
To ensure a complete and accurate count, the Census Bureau counted people at their usual residence, which was the place where they lived and slept most of the time, with a few exceptions. For more details about where people were counted, you can view the Who to Count page.
The Census Bureau has special processes in place to ensure that everyone in the 50 states, District of Columbia, and five U.S. territories was counted.
