Geography and climate do not justify Russia's relatively low population. Russia has rich lands and other natural resources. The economy alone does not explain low population either. The immense size of Russia and the distance of many areas from the sea precipitate the dominance of the oppressive continental climate, which is prevalent in all parts of the country except for the tundra and the extreme Southwest.
Compared to the US, the population of Russia is only 143 million. Though Russia is the most sizeable country in the world concerning land and size, the population is less than half the US population.
