What was the approximate time reduction achieved by Hollerith's system for the 1890 US Census processing?
Answer
Compilation time was dramatically reduced from seven to eight years to just over a single year
The effectiveness of Hollerith’s electromechanical invention was demonstrated by the drastic reduction in processing time for the 1890 US Census. The preceding census required approximately seven to eight years to complete the compilation and processing manually. Hollerith's system, utilizing electrical tabulators and sorters, managed to reduce this lengthy period significantly, bringing the total compilation time down to just over one year, illustrating the massive processing capacity unlocked by mechanizing data interpretation.
