Report of the Medical Officer of Health. 15
The Infantile Mortality for the year was slightly higher
than in 1920, which was the lowest infantile mortality ever recorded
in the Borough.
It was quite anticipated that there would be a marked increase
in the infantile mortality during the year, owing to climatic
conditions, but this fortunately did not occur.
In 1911, when the climatic conditions were somewhat similar
the infantile mortality reached the abnormally high rate of 122
per 1,000 births, but owing, without doubt, to the educational
campaign carried on, both by the officials of the Sanitary Authority
and the Infant Welfare Centres, the mortality was only 67
per 1,000.
The following Table shows the percentage of deaths at different
age periods to the total infantile mortality for the year and
for the five previous years. It will be noted that there has been
a slight decrease in the percentage under four weeks compared
with the five years' average, and a slight increase at three to six
months, and at nine to 12 months, while at the other age periods
the rate was lower.
