If you had a conversation about the growing gap between rich and poor almost anywhere in today’s world, you would very likely refer to “the top one percent,” a phrase that evokes the skyrocketing wealth of the superrich. A similar conversation in West Germany in the 1970s or 1980s would have revolved around the latest movements in wage earners’ aggregate share of the national income, evoking images of a society divided into employers and employees. In 1980s Britain, you might have talked about income growth among the bottom tenth of the population, as the government tried to steer the discussion away from income relativities and overall inequality.
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.
