Over four decades ago, the distinguished epidemiological psychiatrist Norman Sartorius wrote, “the history of psychiatric classification is in fact a history of psychiatry.” During the 1960s and 1970s, Sartorius had been at the center of research by the World Health Organization (WHO) on the international classification and prevalence of mental disorders. During that era, the organization significantly transformed its classificatory manual, the International Statistical Classification of Diseases and Related Health Problems (ICD), releasing the ICD–9 in 1977. The ICD is the standard international manual for recording mortality and morbidity data for insurance and epidemiological purposes. WHO is currently in the final stages of completing its latest update to the text, ICD–11.

When an architect in Germany designs a building, chances are that she will reach for “the Neufert” at some point—Ernst Neufert’s (1900–86) Bauentwurfslehre or Building Design Handbook. Now in its 41st German edition, with 18 international editions, the book comprises an encyclopedic assortment of measures and floor plan elements that still serves as a reference for the organization of competition briefs and the execution of commissioned buildings.

In the first week of October 1932, an International Conference on Migration Statistics was held in Geneva. Over the course of five days, some thirty statisticians from twenty-six countries discussed how to produce more reliable international migration statistics. This kind of methodological discussion about statistical standardization was not at all unusual in the new world of international organization. Since 1920, the standardization of statistics had become an ordinary activity in the “Palace” of the International Labour Organization and the League of Nations in the hills above Lake Geneva.
The International Conference on Migration Statistics offers particularly interesting insights into the historical attempt by international organizations to measure the world. On the one hand, “international migration” was not yet a category in scholarship and policy making. It was an international invention intended to bring together the existing categories of “emigration” and “immigration.” Before this time, these last two categories were perceived as two fundamentally separate phenomena. Perhaps more plainly than other objects targeted by statistical analysis, “international migration” was connected to the effort to construct a new international understanding of the world after the Great War.
