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. 15 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."
16 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.
"The greater the number of children," as Hamburger puts it, "the greater the cost of each survivor to the family and to the State."
Russia presents not only the most typical but the most stupendous and appalling example of this process. Thirty years ago the mortality of infants under one year was three times that of Norway, nearly double
