But they did--starting with the 1890 Census. Hollerith developed the
original punched card with rectangular holes (I never heard the punch-outs
called "chads" until last month) to compile the 1890 census statistics,
and they were used in each following census until 1950. The 1960 census
was compiled using the Univac computer.
