sanitation upon the public health can be measured. Unfortunately,
it is somewhat difficult to ascertain the exact death rate
of each ward. The previous address of persons who died in
public institutions outside the district was not this year ascertained
; it is hoped that this defect will be remedied next year.
Of the deaths registered within the district, 139 belonged to the
North Ward, 184 to the East Ward, and 213 to the West Ward.
Again, the population of each ward can only be approximately
estimated. With the assistance of the Surveyor and
Accountant, the population of each ward has been calculated as
follows:—
North Ward 15,000
East Ward 19,000
West Ward 16,000
The death rate of each ward based upon the estimate
would be:—
North Ward 9.3 per 1,000
East Ward 9.7 per 1,000
West Ward 13.3 per 1,000
These figures do not include the deaths of the residents in
public institutions outside the district.
ZYMOTIC DISEASES.
Deaths 66. Death rate 1.3.
The so-called Zymotic death rate includes deaths from
seven Zymotic Diseases namely, Small Pox, Measles, Whooping
Cough, Scarlet Fever, Diphtheria, Fever and Diarrhoea. In some
quarters it still retains its popularity as an index of the seven
diseases. An epidemic of Measles or Whooping Cough may
affect the magnitude of the Zymotic death rate more profoundly
than an excessive prevalence of Diphtheria, Enteric Fever or
Diarrhoea, though the former diseases may be but little dependent
on sanitary conditions. Moreover, some of the other preventable
diseases, such as Phthisis and Puerperal Fever are not included.
