It is thus clear that the birth-rate combined with the death-rate constitutes a delicate instrument for the measurement of civilisation, and that the record of these combined curves registers the upward or downward course of every nation. The curves, as we know, tend to be parallel, and when they are not parallel we are in the presence of a rare and abnormal state of things which is usually temporary or transitional. It is instructive from this point of view to study the various nations of Europe, for here we find a large number of small nations, each with its own statistical system, confined within a small space and living under fairly uniform conditions. Let us take the very latest official figures (which are usually for 1913) and attempt to measure the civilisation of European countries on this basis. Beginning with the lowest birth-rate, and therefore in gradually descending rank of superiority, we find that the European countries stand in the following order: France, Belgium, Ireland, Sweden, the United Kingdom, Switzerland, Norway, Scotland, Denmark, Holland, the German Empire, Prussia, Finland, Spain, Austria, Italy, Hungary, Serbia, Bulgaria, Roumania, Russia. If we take the death-rate similarly, beginning with the lowest rate and gradually descending to the highest, we find the following order: Holland, Denmark, Norway, Sweden, Switzerland, the United Kingdom, Belgium, Scotland, Prussia, the German Empire, Finland, Ireland, France, Italy, Austria, Serbia, Spain, Bulgaria, Hungary, Roumania, Russia.
