Last week the Census Bureau released the results from the United States' most massive participation movement in history, the 2010 U.S. Census. Conducted every ten years as mandated by the U.S. Constitution, the census is the basis for determining the number of seats given each state in the House of Representatives and for the allocation of federal funds. The Census' user-friendly website makes it easy for everyone to view and use the census data.
