Uninhabited, Unused, Untravelled, or Uncharted? Sparsely or Unpopulated Areas and Gridded Population Data

Résumé

Gridded data sets representing the distribution of the human population are increasingly available globally today. If most of the attention they draw is directed toward inhabited areas, in this article, the authors turns to very sparsely or unpopulated areas, which allow for a renewed exploration of their reality and a reflection on the essence of ”unpopulatedness.” To do so, the author reflects on the multiplication of gridded population data sets and the methods used to produce them, using unpopulated areas as a revealing factor of the limits of algorithms. In the second part, different geographical concepts related to uninhabited areas are explored to show that their reality is not clear-cut and more difficult to grasp than data sets based on population density indicate. Very sparsely populated or unpopulated areas include a vast array of regions and situations, from areas not permanently settled but heavily used and travelled to areas that are very infrequently visited. Their levels of transformation by human activities, frequentation, or accessibility differ wildly, so it is impossible to consider them as a unique or coherent category. In conclusion, the author calls for going beyond the “nobody lives there” vision, popular on the internet, by understanding better how population gridded data sets are constructed and by complementing them with new quantitative and qualitative data, which could help distinguish between several nuances of occupation in space and time.
