About The 2000 Census For the 2000 census, the Census Bureau employed more than 500,000 people to visit the homes of people who did not return their mail-in census form. The 2000 census turned out to be the most accurate in history, with the lowest undercount of minorities of any previous census. Taken every ten years, the census is the most comprehensive source for these types of statistics because it is charged by the U.S. Constitution to count every resident of the United States. Besides its original purpose of counting people for congressional seat alignment, the census is also an invaluable source of information for government and business planning, such as realtors, entrepreneaurs, business management, site location, and other important endeavors.   Start your order now!
