>>12646908> Population density has a huge impact on pathogen spread.Great, but since you use the total country population density, the Moon solution will do wonders. Actually, judging by the rest of your comment, you understand that well. Ok, let's make it very clear:
Sweden has Lapland wastes, they don't impact its covid stats in any way.
Russia has Siberian tundra, it does not impact covid in any way.
Denmark has Greenland, it does noes not impact covid in any way.
People live in capitals and large cities. They don't live in empty northern space, or in the space between cities. That's why total population density shows exactly nothing.
