(3) The birth rate of civilized countries has also fallen markedly during the nineteenth century, especially during the latter half. On the whole, this is a good thing. The birth rate should decrease with the death rate. This leaves more energy to be used in other things; but when the birth rate falls more rapidly than the death rate or falls beyond a certain point, it is evident that the normal growth of a nation is hindered, and even its extinction may be threatened. While an excessively high birth rate is a sign of low culture on the whole, on the other hand an excessively low birth rate is a sign of physical and probably moral degeneracy in the population. When the birth rate is lower than the death rate in a given population, it is evident that the population is on the way to extinction. In order that a birth rate be normal, therefore, it must be sufficiently above the death rate to provide for the normal growth of the population. On the whole, it seems safe to conclude that we have no better index of the vitality of a people, that is, of their capacity to survive, than the surplus of births over deaths. Such a surplus of births over deaths is also a fairly trustworthy index of the living conditions of a population, because if the living conditions are poor, no matter how high the birth rate may be, the death rate will be correspondingly high, and the surplus of births over deaths, therefore, relatively low.
Vital statistics are, therefore, an indication of more than the mere health or even the material condition of a given population. Probably there are no social facts from which we may gather a clearer insight into the social conditions of a given population than vital statistics.
Without going into the vital statistics of modern nations in any detail, the following table of birth rates and death rates will serve to illustrate the decrease in the death rates and the birth rates of the three leading European nations, the birth rate being computed the same as the death rate, that is, the number of births per thousand annually of the population:
DEATH RATE
1871-1890 1893-1902 1904
England ………………. 20.3 17.6 16.2
Germany ………………. 26.0 21.5 19.6
France ……………….. 22.8 20.8 19.4
BIRTH RATE
1871-1890 1893-1902 1904
England ………………. 34.0 29.3 28.0
Germany ………………. 38.1 35.9 35.2
France ……………….. 24.6 22.8 20.9
From the above table it is evident that while birth rates and death rates have been declining in all civilized peoples, the decline has been unequal in different peoples. Both England and Germany in the above table show still a good surplus of births over deaths; in the case of England in 1904 this surplus being 11.8 per thousand of the population annually, while in the case of Germany it was 15.6. In the case of France, however, the surplus of births over deaths for a number of years has been very insignificant, and in the year 1907 there were actually about 20,000 more deaths than births in all France (773,969 births against 793,889 deaths). France's population has, therefore, been practically stationary for a number of years, while within the last year or two it seems to be actually declining.
