ABSTRACT
The economic evolution of the world, of which authors perceive but the dawning, has coincided with various circumstances which have in the greater number of the nations provoked a rapid increase of their population. When a country possesses a great extent of territory which is sparsely populated, such as Russia, the United States, or England with her colonies, the increase of her population evident advantages, or at least for a certain time. When the population of Germany attained the same density of 224 to the square mile, she in turn was obliged to look about for colonies. A consequence at first of excessive population, the tendency to emigrate becomes a cause in its turn, and contributes yet more to increase this excess. The decreasing increase of population is to be seen almost everywhere, even in countries where the birthrate has been momentarily highest.
