In Australia, Belgium, Hungary, Italy, Norway, Prussia, Spain, and Sweden both the rate from childbirth and that from puerperal septicemia remained almost stationary during the periods studied.
The total rate for Scotland shows a definite increase, though the rate from puerperal septicemia has decreased. (See Table XVI, p. 66.)
Communities are still to a great extent indifferent to or ignorant of the number of lives of women lost yearly from childbirth; many communities which are proud of their low typhoid or diphtheria rates ignore their high rates from childbed fever. Communities are only beginning to realize that among their chief concerns is the protection of the babies born within their limits, and necessarily also of the mothers of those babies before and at confinement.
DEATH-REGISTRATION AREA
The statistics of causes of death are available only for a certain portion of the United States, included in the so-called “death-registration area.” Unlike other civilized countries, the United States has no uniform laws for the registration of births and deaths. Moreover, the efficiency of enforcement of existing laws varies greatly in the different States. The Bureau of the Census in 1880 therefore established a “death-registration area,” which comprises “States and cities in which the registration of deaths is returned as fairly complete (at least 90 per cent. of the total), and from which transcripts of the deaths recorded under the State laws or municipal ordinances are obtained by the Bureau of the Census.” In 1880 this area included but 17 per cent. of the total population of the United States. As States and cities have passed better laws and obtained better enforcement they have been added to the registration area; the latter has increased greatly in size, but even in 1913 included only 65.1 per cent. of the population of the United States. For the remaining 34.9 per cent. of the population of the country we have no reliable statistics. This 34.9 per cent. includes the population of the greater number of the Southern States and of many Middle Western and Western States outside of certain registration cities in these States which are included in the area. No statements can be made, therefore, of the number of deaths from any cause in the United States as a whole; only an estimate can be made on the assumption that for any cause of death the same rate prevails in the remainder of the United States as in the death-registration area.
PROVISIONAL BIRTH-REGISTRATION AREA
The registration of births is still more incomplete in this country than is the registration of deaths. For 1910 the United States Bureau of the Census established a “provisional birth-registration area,” including the New England States, Pennsylvania, Michigan, New York City and Washington, D. C.
Death rates per 1,000 births.—As shown above, the method of computation of death rates which gives the clearest picture of the hazards of childbirth is that which takes into account only the women giving birth to children in that year. This is the method in use in a large number of foreign countries. The advantages of the method are self-evident. A demonstration of the superiority of this method of computation is obtained by a study of the tables giving the death rates from these diseases for foreign countries. In certain countries, as for instance Belgium and Hungary, there has been in recent years an apparent fall in the average death rates as computed per 100,000 population, while the average rates computed per 1,000 live births have remained stationary or risen. This phenomenon is due, evidently, to a decline in the birth rate in these countries during these years, and shows how misleading the rates as given per 100,000 population undoubtedly are in countries with declining birth rates. Whether a fall in the birth rate has occurred in the United States is not known. If it has occurred in the registration area, it would mean that the slight rise in rates per 100,000 population between 1900 and 1913 means a greater rise in rates computed according to the number of births. Such an error might compensate for the opposite error due to the more complete registration of deaths from childbirth in the later years of this period.
Miscarriages are not reportable in any country, although a number of miscarriages (as the term is usually defined) probably are reported as stillbirths in certain countries. The fact that women having miscarriages are not considered in the base would lead to a somewhat higher death rate than that which would express absolutely the number of deaths per 1,000 women at risk.
