From 1863-81 the Provincial Statistical Committees in the Baltic provinces of Estland, Livland, and Kurland carried out a series of local censuses to count the population and collect data on various aspects of society.

The stacked bar charts enabled viewers to easily compare Reval's various districts. For example, the data visualisation drew readers' attention to how Reval's I district (Fischermay, or today's Kalamaja) was the most religiously diverse. It was home to the largest proportion of non-Lutherans (Orthodox, Catholics, and Muslims). 19th-century Fischermay was an industrial district that was located next to the port and  Patarei Sea Fortress , used at the time as military barracks. Many of the workers, sailors, merchants, and soldiers living in this part of the city had moved to the Baltic provinces from other parts of the Russian Empire, thereby contributing to the multiconfessional character of this district.

‘In general, confession was often mixed up with nationality, so that it is not uncommon for people who, like everyone in their immediate vicinity are ethnically Estonians, spoke German and were in name and by ancestry Estonian, were counted as Russians because of their Greek confession or were counted so by others, and so it happened, for example, that in one and the same family one Greek Orthodox child was referred to as of Russian nationality and the other Lutheran as of Estonian nationality.’ - Paul Eduard Jordan, Die Resultate der ehstländischen Volkszählung vom 29. December 1881 in textlicher Beleuchtung (Reval, 1886), p.24

These cartograms clearly show that the three Baltic provinces of Estland, Livland, and Kurland stood out from by their relatively low proportion of Orthodox and high number of Protestants. These maps reinforced the idea of the Baltic provinces as a religious borderland, at the fringes of the Orthodox world.
