The English Registrar-General in 1907 estimated the natural increase by excess of births over deaths as exceptionally high (higher than that of England) in several Australian Colonies, in the Balkan States, in Russia, the Netherlands, the German Empire, Denmark, and Norway, though in the majority of these lands the birth-rate is very low. On the other hand, the natural increase by excess of births over deaths is below the English rate in Austria, in Hungary, in Japan, in Italy, in Sweden, Switzerland, Spain, Belgium, and Ontario, though in the majority of these lands the birth-rate is high, and in some very high.[102] In most cases it is the high death-rate in infancy and childhood which exercises the counterbalancing influence against a high birth-rate; the death-rate in adult life may be quite moderate. And with few exceptions we find that a high infantile mortality accompanies a high birth-rate, while a low infantile mortality accompanies a low birth-rate. It is evident, however, that even an extremely high infantile mortality is no impediment to a large natural increase provided the birth-rate is extremely high to a more than corresponding extent. But a natural increase thus achieved seems to be accompanied by far more disastrous social conditions than when an equally large increase is achieved by a low infantile death-rate working in association with a low birth-rate. Thus in Norway on one side of the world and in Australasia on the opposite side we see a large natural increase effected not by a profuse expenditure of mostly wasted births but by an economy in deaths, and the increase thus effected is accompanied by highly favourable social conditions, and great national vigour. Norway appears to have the lowest infantile death-rate in Europe.[103] Rubin has suggested that the fairest measure of a country's well-being, as regards its actual vitality--without direct regard, of course, to the country's economic prosperity--is the square of the death-rate divided by the birth-rate.[104] Sir J.A. Baines, who accepts this test, states that Argentina with its high birth-rate and low death-rate stands even above Norway, and Australia still higher, while the climax for the world is attained by New Zealand, which has attained "the nearest approach to immortality yet on record."[105] The order of descending well-being in Europe is thus represented (at the year 1900) by Norway, Sweden, Denmark, Holland, England, Scotland, Finland, Belgium, Switzerland, Germany, Ireland, Portugal, Italy, Austria, France, and Spain. On the other hand, in all the countries, probably without exception, in which a large natural increase is effected by the efforts of an immense birth-rate to overcome an enormous death-rate the end is only effected with much friction and misery, and the process is accompanied by a general retardation of civilization.
