Abstract: Discusses the development of computer software for the Public Use Microdata Samples (PUMS), which are random samples taken from the US censuses from 1850 to 1920. Because each census was done differently, the Integrated Public Use Microdata Series (IPUMS) was developed so that various PUMS could more easily be compared. Once the IPUMS was finished, the University of Minnesota's Social History Research Laboratory developed the computer software needed to utilize the PUMS data sets. This was a two-step process. First, data-entry software packages were created to upload the information into microcomputers. Once this was done, a larger UNIX workstation was used to do the post-entry processing so that the data could be checked, verified, and recoded into numeric form.
