The Census has always been “Big Data,” with or without computers and the automation of information.

Consider just one use of today’s big data with a deep history and a major impact on computational technology: keeping track of a country’s citizenry. This has often been accomplished through a periodic counting, or census. Many references to censuses exist in the ancient world, from Egyptian tomb inscriptions and the Hebrew Bible to, perhaps, most famously, the “worldwide” Roman census described in the Book of Luke in the New Testament.
