The physical reason for the low density in Western Europe is the climates. They are more drastic because they are farther inland on the continent and the warmth from the ocean gusts and anticyclones do not have as much of an effect as near the coasts. The last category is under 25 people per square mile. This is the smallest category in Europe. Physical factors are the main reasons for this. The climate types are mostly subarctic and tundra regions. Not much can be grown in ground that is frozen part of or most of the year, so agriculture has not flourished and drawn people to the region like in the Great European Plain. Along with that, there are not a great amount of minerals, only uranium deposits. The landforms play a part also with the Scandinavian Shield, Scotland, and Iceland having higher elevations with rocky soil and coasts.These are the most important factors that I thought accounted for the population distribution in Europe....
