A census is a "snapshot" of the entire population at a single point in time. The U.S. Census determines how many people reside within the country's borders, who they are, and where they live. Every 10 years since 1790, data from the decennial census have been used to apportion seats in the U.S. House of Representatives, as mandated by the U.S. constitution. With 860,000 temporary workers and a cost of $4.5 billion, the 2000 Census was the largest peacetime mobilization of resources and personnel by the federal government. The 2010 Census, which will take place next April, is projected to cost as much as $14 billion.
