respectively, and totals of 693 and 859 for the years 1921 and 1922.
These figures, like the figures for deaths of infants under 1 year
of age, also represent an enormous saving in young life (under 5 years
of age).
4.—-Zymotic Death-Rates.
The zymotic death rate is made up of the total deaths from the
seven principal zymotic diseases, viz., smallpox, measles, scarlet
fever, diphtheria (including membranous croup), whooping cough,
" fever" (including typhus, typhoid or paratyphoid or enteric
and simple continued or ill-defined) and diarrhoea.
The total number of deaths registered within the Borough from
these diseases is 176—69 strangers belonging to other districts
and 107 parishioners who died within the Borough ; whilst, in
addition, 34 parishioners died from these diseases outside the
Borough. Subtracting the strangers and adding the parishioners
who died outside the Borough, there is a corrected total of 141,
giving a zymotic death-rate (corrected) of 0.4 per 1,000 inhabitants,
the lowest ever recorded. As in the case of the general death-rates,
the zymotic death-rates vary in the inner and outer districts, viz.,
0.7 as compared with 0.2 per 1,000 population respectively (vide
Table D).
Taking the zymotic diseases separately, the same decline is
noticed, e.g., measles 0.07, whooping cough 0.04, diarrhoea 0.1,
typhoid fever 0.0, diphtheria 0.15, scarlet fever 0.03, smallpox
0.0, per 1,000 of the population.
The different rates of mortality from different diseases and
groups of diseases during 1922 and 1923 are given in terms of the
total deaths (corrected) in Table E, which gives also the corrected
deaths from the chief infantile diseases, expressed in terms of the
infantile population (i.e., the number of births registered as corrected
by the Registrar-General).
Tuberculosis Death Rates.
The tuberculosis corrected death-rate for 1923 is 1.1, i.e.,
329 deaths from all forms of tuberculosis per 1,000 population,
and the consumption (phthisis) death-rate, 0.8, i.e., 264 deaths
from pulmonary tuberculosis or consumption (phthisis) per 1,000
population.
