SEASONAL MORTALITY.
The greatest number of deaths occurred in January
August and December. The least number in February, May
and October.
Chart D shows the January and December rise was
due to the increased mortality from Respiratory Diseases
(Pneumonia, Bronchitis and Pleurisy).
The sudden increase in August was mainly due to the
advent of Infantile Diarrhoea and Enteritis prevalent during
August and September. (Vide Chart D).
INFANT MORTALITY.
The infantile mortality rate represents the proportion
of deaths occurring among children under one year to the
total number of births registered in the same period.
The number of infantile deaths was 426 or 25.5 per
cent. of the total deaths, equivalent to a mortality of 128 for
every thousand births. This rate compares favourably with
that of 168 for 33 great Towns and 148 for the County of
London. Only four other London Boroughs have a lower rate
—Hampstead, 104; St. Marylebone, 107; Stoke Newington,
115; and Holborn, 124. (Vide Table 10).
ZYMOTIC DEATH-RATE.
The rate is calculated upon the total number of deaths
occurring from the seven principal infectious diseases, viz.:—
Small - pox, Scarlet Fever, Measles, Diphtheria, Whooping
Cough, Typhus and Enteric Fevers, and Diarrhoea.
This group of diseases was responsible for 209 deaths,
or a Zymotic death-rate of 1.62 per 1,000, compared with
2.05 for England and Wales and 2.68 for the 33 great Towns.
It also compares most favourably with other Metropolitan
