## Does the U.S. Census Bureau still use punch cards to process census data?

Computers replaced punch cards at the Census Bureau as computers and magnetic computer tape were introduced in the 1950s.  Today, the agency uses optical character and optical mark recognition software to process census and survey questionnaires.  For more information, visit the Tabulation and Processing Web page.
