4.—Mortality (all aGES).
The different rates of mortality from different diseases and groups
of diseases during 1926 (and 1925) 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 corrected number
.of births, which are taken as the infantile population (i.e, the total
number of births registered and corrected by the Registrar General).
Other tables, in the same way, deal with mortality rates (general) at all
.ages per 1.000 of the estimated population.
5.—Zymotic Death.Rates.
The zymotic death.rate is made up of the total deaths from the
seven principal zymotic diseases, viz.: small.pox, measles,* scarlet
fever, diphtheria (including membranous croup), whooping cough,
" fever" (including typhus, typhoid and paratyphoid or enteric and
simple continued or ill.defined) and diarrhoea.
The total number of deaths registered within the Borough from
these diseases is 154—65 strangers belonging lo other districts and 89
parishioners who died within the Borough ; whilst, in addition, 71
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 160, giving a zymotic death.rate (corrected)
of 0.51 per 1,000 inhabitants As in the case of general death rates,
the zymotic death.rates vary in the inner and outer districts, viz., o.8
in the former (congested and crowded) as compared with 0 3 in the
latter (less congested and less crowded) per 1,000 population (vide
Table D).
Taking the seven principal zymotic diseases separately, the
corrected death.rates per 1,000 of the estimated population are:—
Small-pox 0.003, nieasles, 0.22. whooping cough o.6, scarlet fever
0 01, diphtheria 0.13, "fever" 0.006, and diarrhoea o.o.].
General and Zymotic Death.Rates.
Whilst the statistics for the infantile and child populations can
only be described as remarkable, the statistics for the population at all
ages are most satisfactory and, practically, record the lowest mortality
rates (both general and zymotic).
The general corrected death.rate for the year 1926 is 11.5 per
1,000 of the estimated population, as compared with respective yearly
averages of 18.4, 14.9, 14.9 during the decennia 1891-1900 (Parish),
1901-10 (Borough) and 1911-20 (Borough), and 12.3 during the
quinquennium 1921-25 (Borough) ; whilst the zymotic death.rate
(corrected) for the year 1926 is 0.5 per 1,000 of the estimated
population as compared with respective yearly averages of 2 4, 1.5 and
1.1 during the same decennia, and 0 6 curing the same quinquennium.
* One death registered from german measles is included amongst the "measles"
deaths.
