The United States Census Bureau was the first government bureau to use punch cards for data collection. They began using punch cards in the late 19th century to process and tabulate census data. This technology greatly improved the speed and accuracy of data processing and became widely adopted by various government agencies and industries.
Punch cards were used by computer programmers back when computers used punch cards. The cards were used to tell the computer what to do. Programmers had a machine that they used to write computer programs and it would punch the holes in the cards. It took a lot of cards just to write on program.

Punch cards store data. That data can then be analysed by feeding the cards into a punch card reader.
