How long did it take for the census data to be calculated after the invention of Herman Hollerith's machine?

The analysis and processing of census data became significantly more efficient following the introduction of Herman Hollerith's tabulating machine in the late 19th century. Specifically, the 1890 U.S. Census was notably completed in just 6 weeks thanks to this innovative technology. Hollerith's machine utilized punched cards to record data, which greatly accelerated the counting process compared to the manual methods employed in previous censuses. This drastic reduction in time highlighted the impact of automation on data processing and set the stage for future developments in statistical analysis and data management. Thus, the choice indicating 6 weeks accurately reflects the historical achievement of efficiently processing census data with Hollerith's invention.
