necessary to take into account in the determination of the
death-rate.
Death-Rate.—Calculated from the number of deaths
registered and the foregoing estimate of the population, the
death-rate was 19.89 per 1000 persons living on an average
during the year. But, as explained in previous reports,
this rate so determined is inclusive of the mortality of the
Surrey County Lunatic Asylum, St. Peter's Hospital and
the Hospital for Incurables, the inmates of which institutions
are derived, with a fractional exception, from without
the parish, undergo no natural increase, and are subject to
a high mortality; they moreover contribute such a large
proportion of the deaths, amounting last year to nearly a
fourth part, that a calculation so derived must be entirely
worthless. It becomes necessary, therefore, in order to
arrive at the natural death-rate of the Sub-district, to
eliminate from the calculation the population and mortality
of the above named institutions, and, for greater
accuracy, to add to it the deaths of the Wandsworth
parishioners who died in the Infirmary of the Union
during the year. Thus determined, after correction made
in the manner indicated, the death-rate of the past year
was 16.73 per 1000 of the inhabitants. This rate, although
upwards of 1 per 1000 higher than that of last year, is still
somewhat below that of rural districts.
Birth-Rate.—The births numbered 679; 373 of males
and 306 of females, representing a rate, calculated on the
foregoing estimate of the population, of 30.53 per 1000
persons living of all ages. The rate of natural increase
was 13.80 per 1000.
The following Table contains a summary of all the
causes of death arranged in accordance with the classification
of the Registrar-General, shewing the sex, social
position and age at death at different periods, and particularizing
the several diseases of the Zymotic class:—
