Using 120 million forms, 5,000 tons of paper and 85 tons of ink, the survey will amass and tabulate more than 3 billion answers and record them on 5,000 miles of microfilm. To process this avalanche of data, the Census Bureau has had to design (and patent) special scanning equipment that will be plugged into a giant UNIVAC 1100 computer around the clock for months. Meanwhile, an army of 250,000 census takers, or "enumerators," and 15,000 office workers are being recruited; they...

When the checks were made out, the ink would be perfectly visible against the rosy-hued ground. But when the draft was microfilmed, he figured, it would become a blank; anything written or printed would disappear...
