Accurate and scientific map showing the population levels of the United States and Canada after the census of 1880.
Thematic map of the United States showing the population levels in both the United States and Canada, emphasizing the difference of population density between the east and the west of the continent as late as 1888. The inset on the lower right shows the density of recently arrived immigrants while the density on the lower left shows the density of the colour population.

The <i>Geographische Mitteilungen</i>, in which this map was originally published, is the oldest German language geographical journal - its first issue was in 1855 and it finally closed its doors in 2004. The magazine was conceived and edited by August Heinrich Petermann and published by the venerable firm of Justus Perthes in Gotha, Germany.
Its first article reported on an expedition into North Africa and the Sahara by Heinrich Barth and Adolf Overweg. This report was enough to secure a circulation of 4000 for the fledgling magazine and, more importantly, encouraged other important scientist-explorers of the day who were attracted by the magazine’s heavy scientific emphasis to send in their own reports. These included Hans Meyer, the first man to ascend the Kibo crater on Mount Kilimanjaro, Sven Hedin, the Swedish explorer of Central Asia and the Himalayas, and Alfred Wegener, the geoscientist who pioneered the theory of continental shift which led to the modern theory of plate tectonics.
In comparison to its contemporaries, such as the Geographical Journal of the Royal Geographical Society, the <i>Mitteilungen</i> had a far greater interest in ethnography and the physical and natural sciences, leading to the inclusion of many fascinating, but sometimes obscure, maps on the most recent theories related to climatology, meteorology, botany, and zoology.
