This book analyses the international development of the census by comparing the history of census taking on all continents and in many countries. The timeframe is wide, from male censuses in the Bible to current censuses covering the whole population. There is a focus on the efforts and destinies of census takers and the development of methods used to collect information into the census questionnaires. The book highlights international cooperation in census taking, as well as how computerized access to census data facilitates genealogical studies and statistical research on both historical and contemporary societies. It deals with such questions as "Why did the French and British gentry block efforts at census taking in the 18th century?"; "What role did German censuses play during Holocaust?"; Why were the Soviet census directors executed as part of the Moscow processes?"; "Why did US states sue the Census Bureau in the 1970s?"; "How do wars and revolutions affect census taking?". The text ends by discussing whether the days of the population census as we know it are numbered, since countries exceedingly construct censuses by combining information from population registers rather than with questionnaires.

This fascinating three-thousand-year history of the census traces the making of the modern survey and explores its political power in the age of big data and surveillance. In April 2020, the United States will embark on what has been called "the largest peacetime mobilization in American history": the decennial population census. It is part of a tradition of counting people that goes back at least three millennia and now spans the globe. In The Sum of the People, data scientist Andrew Whitby traces the remarkable history of the census, from ancient China and the Roman Empire, through revolutionary America and Nazi-occupied Europe, to the steps of the Supreme Court. Marvels of democracy, instruments of exclusion, and, at worst, tools of tyranny and genocide, censuses have always profoundly shaped the societies we've built. Today, as we struggle to resist the creep of mass surveillance, the traditional census -- direct and transparent -- may offer the seeds of an alternative.

The population and housing census is part of an integrated national statistical system, which may include other censuses (for example, agriculture), surveys, registers and administrative files. It provides, at regular intervals, the benchmark for population count at national and local levels. For small geographical areas or sub-populations, it may represent the only source of information for certain social, demographic and economic characteristics. For many countries the census also provides a solid framework to develop sampling frames. This publication represents one of the pillars for data collection on the number and characteristics of the population of a country.
