Engadget reports on a new Windows Mobile PDA that census takers might use for data collection. bandwidth is provided by Sprint. The batteries last 10 hours – an amazing result on a PDA that is deisgned for heavy data entry and network usage in the field.
The US Constitution requires a national census every 10 years. One early use of Hollerith cards was in the 1890 US Census. The previous census in 1880 used manual methods and took 9 years to complete. With Hollerith’s cards and tabulation equipment, the Census Bureau finished the 1890 count within 7 years at twice the cost of the 1880 census. The reports and data were far more complex and complete than any previous census, however.
I keep a stack of vintage Hollerith cards in my office, so I can remember the good old days.
