As suicides are tabulated in the Health Office of the District of Columbia by months, I was able to ascertain, furthermore, that the decrease began, not in the first month of the year, but in the spring months, when the war excitement became epidemic. Normally, the suicide rate should have risen, from January to June, in accordance with the seasonal law; but, instead of so doing, it fell rapidly at the very time when it should have been approaching its maximum. The colored population of the city, taken separately, was affected in the same way and to an even greater degree, the number of suicides among the blacks falling off fifty-six per cent., as compared with fifty per cent. among the whites. The number of suicides in both races remained low throughout the year 1899, and then rose suddenly in 1900, an almost precise correspondence with the suicide curve of the nation as a whole.
During our Civil War the suicidal tendency was affected in the same way, but to a much greater extent. I have not been able to find mortality statistics of the whole country for the period in question, but in New York City the average rate of suicide in the five years of the Civil War was forty-two per cent. lower than the average for the five preceding years, and forty-three per cent. lower than the average for the five subsequent years. In the State of Massachusetts, where accurate statistics were kept, the number of suicides decreased seventeen per cent. in the five-year period from 1861 to 1865, as compared with the five-year period from 1856 to 1860.
In Europe the restraining influence of war upon the suicidal impulse is equally marked. The war between Austria and Italy in 1866 decreased the suicide rate of each country about fourteen per cent. The Franco-German war of 1870-71 lowered the suicide rate of Saxony 8.0 per cent., that of Prussia 11.4 per cent., and that of France 18.7 per cent. The reduction was greatest in France, because the German invasion of that country made the war excitement there much more general and intense than it was in Saxony or Prussia.
An explanation of the decrease of suicide in time of war may be found, perhaps, in the power that any strong excitement has to change the current of thought and substitute one emotion for another. Suicide, among civilized peoples, is largely due to morbid introspection and long brooding over real or imaginary trouble; and anything that takes a man's mind away from his own unhappiness, and gives him a keen interest in things or events about him, weakens his suicidal impulse. An unhappy man might resolve to end his life, and might load a revolver with the intention of shooting himself; but if he should happen to see a couple of his neighbors fighting in his front door-yard, he would probably lay the revolver aside, for a time, and watch the combat. The cause of his unhappiness would still remain, but the current of his thought would suddenly be diverted into a new channel and his despondency would give way to the excitement of a fresh and vivid interest. War acts upon men in the same way, but with greater force.
Then, too, war restrains suicide by strengthening the bonds of social sympathy and drawing large masses of people more closely together. The unhappy man always thinks of himself as lonely, isolated, and out of harmony with his environment; but when, as a result of the victories or defeats of war, he finds himself participating in the triumph or sharing the grief of thousands of other persons, the mere consciousness of sympathetic association with his fellow-men becomes a source of comfort and consolation to him and makes his life more endurable. But war is not the only agency that exerts a restraining influence upon self-destruction. Any great calamity which causes intense public excitement, and which at the same time draws people together in friendly sympathy and coöperation, lowers the suicide rate. The calamity may greatly intensify suffering, and may make life, for a time, almost intolerable; but it does not increase the number of persons who try to escape from life; on the contrary, it reduces it.
San Francisco Earthquake Decreased Suicides
A striking illustration of this fact was furnished by San Francisco in 1906. Before the earthquake and fire of April 18 the suicides in that city averaged twelve a week. After the earthquake, when the whole population was homeless, destitute, and exposed to hardships and privations of every kind, there were only three suicides in two months. The decrease, therefore, in the suicide rate was more than 97 per cent. This surprising result of a disheartening and depressing calamity was due partly to the excitement of life under new and extraordinary conditions, and partly to the feeling, which every man had, that he was enduring and working with a host of sympathetic comrades, and not suffering and striving alone. If life were always vividly interesting, as it was in San Francisco after the earthquake, and if all men worked and suffered together as the San Franciscans did for a few weeks, suicide would not end ten thousand American lives every year, as it does now.
The dependence of suicide upon such conditions as age, sex, occupation, and religion does not offer any problem as difficult and baffling as that involved in the relation of suicide to weather, nor any as curious and suggestive as that which connects suicide with war; but there is hardly a phase of the subject that does not present some more or less interesting question. The researches of Durkheim and Gubski show that, after the period of childhood, the tendency to suicide increases steadily with advancing age. In France, for example, if the population be segregated in groups comprising all persons ten to twenty years of age, all persons twenty to thirty years of age, all persons thirty to forty years of age, and so on, by decades, the annual number of suicides per million rises as follows: first group 56, second group 130, third 155, fourth 204, fifth 217, sixth 274, seventh 317, and the rate finally reaches its maximum in the group that comprises persons more than eighty years of age.
In the United States, the rate increases from 128 per million, in the age group comprising persons under forty-five, to 300 per million in the age group comprising persons over sixty-five. The figures vary in different countries, according to the hereditary national suicide tendencies; but the steady increase with advancing age is common to all. These statistics would seem to support the pessimistic philosophy of Schopenhauer, and to prove that the longer one lives the less one wants to live; but it must not be forgotten that the suicide rate is a measure of exceptional unhappiness, not of the general welfare.
In the suicidal tendencies of the sexes there is, as might be expected, a very great difference. In all countries and in all parts of the world, suicides among women are far less frequent than among men. The ratio varies from one to two to two to five. This difference is generally attributed to the supposed fact that women are sheltered and protected by men, as well as by their domestic environment, and that, consequently, they suffer less from the wear and tear of life; but I doubt very much the adequacy of this explanation. The life of women, in the world at large, is quite as hard as that of men, and often harder. In the higher and wealthier classes of society women may be, and doubtless are, sheltered and protected; but in the poorer classes they take their full share of the suffering, even if they do not bear the brunt of the struggle.
