Computer Equipment
The 1890 census was the first to use the electric tabulating machines invented by Herman Hollerith. For 1890–1940 details, see Truesdell, Leon E. (1965). The Development of Punch Card Tabulation in the Bureau of the Census, 1890-1940: With outlines of actual tabulation programs. US GPO. In 1946, knowing of the Bureau's funding of Hollerith and, later, Powers, John Mauchly approached the Bureau about early funding for UNIVAC development. A UNIVAC I computer was accepted by the Bureau in 1951.
In order to reduce paper usage and reduce payroll expenses, 500,000 handheld computers (HHC's) were used for the first time in 2009 during the address canvassing portion of the 2010 Decennial Census Project. Projected savings are estimated to be over $1 billion. The further implementation of advanced computer systems in the planning for the 2020 census provides major challenges for an upgrade in the technological broadening of census protocol.

Famous quotes containing the words computer and/or equipment:
“The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.”
—Sherry Turkle (b. 1948)
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
