Report of the Medical Officer of Health.
The first Chart shows the death-rate in the Borough for each
fortnight, compared with the quinquennial average 1906-1910.
The Chart shows that on 10 fortnights the rate was above
that for the previous quinquennium, viz.:—on the fortnights
ended the 25th February, nth March, 25th March, 8th April,
22nd April, 12th August, 26th August, 9th September, 23rd September,
and 21st October.
During the rest of the year the fortnightly rate was under
the quinquennial rates. The highest rate, 17.28, occurred during
the fortnight ending the 25th March, and this was due to the great
number of deaths from Measles and Respiratory diseases; and the
lowest rate during the fortnight ending the 29th July, when it was
7 92 per 1,000.
The next Chart shows the Annual Death-rate per 1,000 during
each week of the year for the whole of London and for each fortnight
for the Borough of Wandsworth.
During the year, with the exception of the four weeks of March,
the rate in this Borough was under the rate for the whole of London.
The highest rate in London was in the third week of August, and
the lowest on the last week of June.
Table XVII. shows the vital statistics of the whole Borough
for the year and for the previous 10 years, as well as the average
for the 10 years.
This Table shows clearly the variations in the births and deaths,
the birth and death-rates, and the infantile mortality for the
decennium, compared with the year 1911.
Compared with the decennial average there has been a considerable
decrease in the birth-rate and a slight decrease in the
death-rate, while the infantile mortality, which for the past 10 years
had shown a most satisfactory decrease, now shows a considerable
increase and was higher than it has been since the year 1906.
It will also be seen that there has been an increase of 291
deaths of residents in Public Institutions outside the Borough,
compared with the 10 years' average.
The corrected death-rate, although higher than it has been since
1906, is still under the 10 years' average.
