1890 Census Hollerith Electrical Counting Machines
The 1890 census was the first to use punchcards and an electrical tabulation system

The Idaho Reconstructed Census of 1890 is an invaluable resource for genealogists due to the loss of the 1890 U.S. Federal Census in a fire.

This reconstructed census was created using various alternative records from 1890, including tax, voter, and other local documents, to provide information on residents of Idaho at that time.

While it may not offer the same level of detail as a full census, it includes names, approximate ages, and sometimes occupations and locations, filling in crucial gaps for researchers tracing family histories in Idaho’s early statehood period.
