On the recordApril 14, 1999
In 1990 the Census was the first Census that we had that was less accurate than the one before it. Because of the 1990 Census, 10 million Americans were undercounted. In the city of Chicago, my hometown, 68,000 Chicagoans were not counted. That is enough Chicagoans to fill Soldier's Field completely at a football game where the Bears were playing. Federal resources are predicated upon the counts. All the statisticians, the National Academy of Scientists and others, indicate that statistical methodology in the 21st century is the way to go, not the 1990 version, where we undercounted people by 10 million.
