2020 Census: The Basics

The United States Constitution requires a count every 10 years of every person who is residing in the U.S., regardless of immigration status or citizenship. The Census Bureau's goal for the 2020 Census is to "count everyone once, only once, and in the right place."

Here are the basic steps in the process:

Step One - Update the address list

The Census Bureau maintains a list of every housing unit in the United States. A housing unit is a house, apartment, condominium, trailer, or other place where people might live. The Census bureau started updating its list for the 2020 Census in 2015, adding new houses and apartment buildings that have been built and removing houses and apartment buildings that were demolished or converted to non-residential uses since the 2010 Census.

Step Two - Solicit responses

Beginning March 12, 2020, the Census Bureau will mail census materials to 95% of homes. (To understand how the other 5% of households are counted, see the section about rural and remote areas.) Eighty percent (80%) of those homes will receive a letter inviting them to respond to the census online using a unique code. The other 20% (where internet access may be limited) will receive the same letter plus a paper questionnaire. All households also will receive information about how to answer the census by telephone. April 1 is Census Day, although most households will receive their materials before then and may respond prior to that date.

Step Three - Collect responses

Respondents will submit one census form listing everyone who lives in their household. Respondents may complete the questionnaire for their household online, by using a paper questionnaire, or by phone (by calling Census Questionnaire Assistance, which will be available from mid-January to early September 2020). Some households without traditional mailing addresses will be counted by Census Bureau employees in person. 

Step Four - Follow up

Households will receive several reminder letters from the Census Bureau if they do not self-respond. The final mailed reminder will include a paper questionnaire. If a household does not complete the questionnaire after receiving mailed reminders, beginning in May 2020 they may receive a phone call or an in-person visit from a Census Bureau employee. Households can continue to self-respond online, using a paper questionnaire, or by phone during the follow up period. 

Step Five - Analyze and disseminate

The Census Bureau will release population totals and other publicly-available data beginning in early 2021.
