Fig. [3].—Shows relation between birth and death-rates from various causes in five districts of London.
Fig. [4].—Relation between the birth-rate and death-rate for various arrondissements of Paris in 1906. (Note that the increase in the Elysée quarter is as high as the average in the quarters of high birth-rate.)
Figs. [5] and [6].—Variations of the total population of birth- and death-rates in the United Kingdom and the German Empire. (Note that the fall in the death-rate corresponds fairly closely to that in the birth-rate.)
Fig. [7].—The same for France. (Note that the population is still increasing, although slowly.)
Fig. [8].—Birth and death-rates for France since 1781. (Note that the rate of increase of population in 1781 was no higher with a birth-rate of 39 per 1,000 than in 1901–6 with a birth-rate of only 21 per 1,000. A fall of 17.8 per 1,000 in the birth-rate has resulted in a fall of 17.5 per 1,000 in the death-rate.)
Fig. [9].—Birth and death-rates and infantile mortality for England and Wales. Also marriage rate, fertility of married women, illegitimacy, and variation of diseases. (Note that the illegitimate birth-rate has fallen to half since the fall of the birth-rate set in.)
Fig. [10].—Birth and death-rates and infantile mortality in the Netherlands. (Notice the rapid increase of population as the death-rate falls, and the great fall of infantile mortality, probably due to the practical work of the Dutch Neo-Malthusian Birth Control League among the poor.)
Figs. [11]–13.—Protestant Countries. (Notice the correspondence between the birth and the death-rates and infantile mortality in all.)
Figs. [14]–16.—Roman Catholic Countries. (Note that the fall of the birth-rate has taken place almost equally with that in the Protestant countries, and with the same result.)
Figs. [17]–[20].—The only four countries in which the birth-rate is approximately stationary. (Notice that the death-rate has not fallen—except perhaps in Russia—and that the infantile mortality has not fallen. Also that the highest birth-rate produces the highest death rate and infantile mortality, and the lowest birth-rate the lowest mortality.)
