living. This estimate is based upon the assumption
that the population has increased since the period
when the census was taken, in the same proportion as it
had done during the preceding ten years: and correction
is made for the deaths in the Surrey County Lunatic
Asylum and the Hospital for Incurables, after the manner
described in previous reports. It will be sufficient to
observe here, that the necessity for such correction arises
from the circumstance that the inmates of these institutions
are derived from without the parish, undergo no
natural increase, and are subject to a high mortality; the
deaths, moreover, are so numerous that, without such
correction, a death-rate determined solely from the deaths
registered would fluctuate with the mortality of these
institutions, and could not therefore represent the natural
death rate of the Sub-district. The death rate deduced
from the deaths registered without the correction above
indicated was 22.69 per 1000.
Birth Rate.-The births registered during the past
year numbered 620, 289 of males, and 331 of females.
The birth-rate was 357 per 1,000 and the rate of natural
increase 17.26 per 1000 persons living of the entire
population.
The following table contains a summary of all the causes
of death arranged in accordance with the classification of
the Registrar General, showing the sex, social position, and
age at death at different periods, and particularizing the
several diseases of the Zymotic class :-
