U.S. Census Day is April 1, and all U.S. residents must be counted on this day, including people of all races and ethnic groups, both citizens and non-citizens. Census questionnaires will be delivered or will be mailed to households through U.S. mail in March. Census workers also will visit households that do not return questionnaires.
The 2010 10-question census questionnaire is one of the shortest in U.S. history and will take 10 minutes to complete. By law, the U.S. Census Bureau cannot share an individual’s responses with anyone, including other federal agencies and law enforcement entities. Visit 2010census.gov for more information.
