THE SIGNIFICANCE OF A FALLING BIRTH-RATE

There is an intimate connection between a high birth-rate and a high death-rate, between a low birth-rate and a low death-rate. It may not, indeed, be an absolutely necessary connection, and is not the outcome of any mysterious "law." But it usually exists, and the reasons are fairly obvious. We have already encountered the statement from an official Canadian source that the large infantile mortality of French Canadian families is due to parental carelessness, consequent, no doubt, not only on the dimly felt consciousness that children are cheap, but much more on inability to cope with the manifold cares involved by a large family. Among the English working class every doctor knows the thinly veiled indifference or even repulsion with which women view the seemingly endless stream of babies they give birth to. Among the Berlin working class, also, Hamburger's important investigation has indicated how serious a cause of infantile mortality this may be. By taking 374 working-class women, who had been married twenty years and conceived 3183 times, he found that the net result in surviving children was relatively more than twice as great among the women who had only had one child when compared to the women who had had fifteen children. The women with only one child brought 76.47 per cent of these children to maturity; the women who had produced fifteen children could only bring 30.66 of them to maturity; the intermediate groups showed a gradual fall to this low level, the only exception being that the mothers of three children were somewhat more successful than the mothers of two children.
