What administrative crisis spurred Herman Hollerith to develop his electromechanical tabulating system?

Answer

The looming decade-long processing time for the 1890 United States Census data

Herman Hollerith was motivated by a severe bottleneck in processing demographic data for the United States Census. The 1880 Census had taken nearly eight years to compile and process manually. This pace created a critical fear that the 1890 count would take over a decade, resulting in data that would be obsolete before its completion. This impending administrative failure necessitated a mechanized solution for rapid tabulation, driving Hollerith to adapt the existing punch card concept using electricity.
