The U.S. Census Bureau is counting on you.
At the beginning of each decade, the U.S. government surveys the American population to count how many people are living in the United States.
The census day is April 1, 2010.
The questionnaires will be mailed out in mid-March. The census bureau recently initiated an advertising campaign to educate citizens about the census and encourage people to fill out the 10-question form and mail it back to the bureau.
