The 2020 Census is a once-a-decade population count of everyone who lives in the United States on April 1. Responses from the census help determine how hundreds of billions of dollars in federal funds are allocated for critical public services and programs in communities around the country each year for the next 10 years.

If you haven’t responded yet, respond now online at 2020census.gov, by phone, or by mail. You should respond for the address of your usual residence (which is the place where you live and sleep most of the time) as of April 1, 2020, even if you were temporarily staying elsewhere on April 1, 2020.

If you’re unsure of how to respond, below is a guide with possible scenarios and where you would count yourself:

If you’ve already responded to the 2020 Census, or someone has responded on your behalf (like parents or roommates), and you’ve since moved, you don’t need to respond again. But if you don’t know whether you were already counted by someone else who lives with you, you should go ahead and respond to the 2020 Census — be sure to count yourself and everyone else living there, providing as much information as you have for each person. The Census Bureau can identify and correct duplicate responses.
