The return for 1925 gives a Death Rate equal to 11.7
per 1,000 population—.5 per 1,000 less than the rate for
England and Wales, and .6 higher than the Bromley rate
for 1924. If we standardise this Death Rate by taking into
consideration age and sex distribution as compared to the
population of England and Wales we get a much truer
indication of the healthiness of the Borough during 1925 as
compared with other towns. This standardisation reduces
the Death Rate for 1925 to 10.3.
It is noteworthy that the Death Rate for the five years
ended 1925 equals the Death Rate for the five years ending
1900. This is explained chiefly by the fact that the average
age of population has increased during these years, and if
this fact is corrected by standardising the death rates, there
has really been a reduction during the period from 11.08 to
9.8.
To indicate the change that occurs in death rates, the
following table of comparison at the various census years
will be of interest :
Percentages of Total Deaths.
1901. 1911. 1921.
Under 14 years of age 37 23 14
Between 14 and 45 years 22 15 16
Over 45 years of age 41 62 70
The chief causes of deaths in the past five years have
been:
Respiratory Disease 17.8% of total deaths.
Heart Disease 14.5% ,, ,, ,,
Cancer 13.2% ,, ,, ,,
Tuberculosis 7% ,, ,, ,,
Premature Births,
Malformations, etc. 4.1% ,, ,, ,,
(or 45% of the total infant deaths
during past 5 years).
