Mortality.—The total number of deaths registered was
499; 263 of males and 236 of females. The average annual
number of the preceding ten years was 462. But as the
deaths of the past year occurred in a greatly increased
population, it is necessary for a correct comparison to raise the
decennial average in proportion to that increase. Such
procedure shews that the deaths of the past year were no less
than 58 below the decennial average corrected for growth
of population in the manner indicated. 116 of the deaths
occurred in the following public institutions situated within
the parish, viz:—in the Surrey County Lunatic Asylum, 93;
in the Hospital for Incurables, 11; in St. Peter's Hospital,
2; and in the Prison, 10. 68 deaths also of Wandsworth
parishioners took place in the following institutions without
the parish, viz:—in the Infirmary of the Union, 52;
and in various London Hospitals, 16. The latter, hitherto
unobtainable, are for the first time included in these statistics.
Death.rate.—Determined by the total number of deaths
registered and the estimated population, the death.rate was
16.71 per 1,000 persons living at the middle of the past year.
Inclusive of the deaths of "Wandsworth parishioners that
occurred in institutions situated without the parish, the rate
was 18.85 per 1,000. Both of these calculations however fail
to represent the natural death.rate of the sub.district,
inasmuch as they include the mortality of the Surrey County
Lunatic Asylum, St. Peter's Hospital, and the Hospital for
Incurables, the inmates of which institutions are, with a
fractional exception, derived from without the parish, undergo
no natural increase and are subject to the highest rate of
mortality; the latter also, which during the past year
constituted upwards of 21 per cent. of all deaths, is so great
