The natural breaks method used to map Imarats density of population shows high contrasts in average population densities, yet these contrasts do not fit the boundaries of the administrative units. method based on the notion of thresholds as well as the dasymetric method established on marked thresholds considering the land use classification inspired from Corine Land Cover nomenclature (https://www.statistiques.developpement-durable.gouv.fr/sites/default/files/2018 -12/clc-guide-d-utilisation-02_0.pdf). Another focal point deals with the choice of a convenient map scale depending not only on the real users' needs, but also on data accuracy and its availability. All things being equal, the question of scale plays a crucial role in the choice of one variant of dasymetric method (Dhieb et al., 2021). The establishment of such map for the whole country of KSA cannot afford a too big scale. The author chose 1 to 2 million since it corresponds to the recent Topographic map of KSA. Since it is the first approach of real population densities, an intermediate map scale was chosen: 1 to 2 million. This choice is also sustained by the existing topographic map at the same scale and the first use (Figure 1). Choosing greater

... departed first from the resulting chorpopleth density maps, based on fixed enumeration units which are the 13 regions or Imarat (Figure 4, Nasr and Dhieb, 2022) and the 136 governorates or Mouhafadhat ( Figure 5, Nasr and Dhieb, 2022). At a first look, these maps emphasize the principle of cartographic generalization of a tedious reality of population's distribution. ...

... they cannot describe accurately the real Saudi densities of population inside the administrative units. For instance, Figure 4 does not tell us that the region of Charguiyya is constituted by a few littoral cities and Al Ahsa oasis, whereas the biggest part is desert and almost empty (Rab AlKhali). We can apply such statement for governorates in Figure 5, but at a lower and finer level. ...
