SEASONAL MORTALITY.
First Quarter —In this quarter of the year there were 1,640 deaths
recorded, as compared with a corrected average of 1,578 in the ten years 18971906.
They were equal to an annual death-rate of 18.90 per 1,000 inhabitants,
as against 18.19 in the years mentioned. The highest number of deaths
occurred in the second week of January, and the lowest in the twelfth week of
the quarter. It is notable that there was an increased mortality, when compared
with that of the preceding ten years, at each age period except three, viz.,1-5 5-15,
and 15-25 years. This was specially noticeable among persons between the
ages of 65 and 75, when the excess of deaths numbered 51; between 75 and
85 it was 23; and above 85 years of age it was 22.
The infantile mortality was also excessive for this period, for it was at the
rate of 148 per 1,000 infants born, as compared with 125 per 1,000 in the
corresponding quarters of the preceding ten years, and with 135 in the twenty
years 1886-1905.
Second Quarter.—There were 1,224 deaths registered, or 18 less than the
corrected average of the corresponding quarters of the preceding ten years;
and they represented an annual death-rate of 14.11 per 1,000 of the inhabitants,
or 0.21 per 1,000 less than in the corresponding decennial periods. The deathrates
ranged from 19.39 in the first week of April to 9.31 per 1,000 in the third
week of June.
The infantile mortality rate showed an improvement in this quarter,
being at the rate of 102 per 1,000 as against a mean rate of 107 in the second
quarters of 1897-1906, and 117 in the same period during- the twenty years
1886-1905.
Third Quarter.—939 deaths were recorded, or 339 less than the corrected
average number registered in the third quarters of the years 1897-1906; and
were equal to the low annual death-rate of 10.82 per 1,000, as compared with a
mean rate of 14.74 per 1,000. The mortality, in -proportion to the population,
was the lowest ever recorded at this season of the year in Islington. This
was due mainly to the decrease in the deaths of infants under one year
old, which fell from an average of 411 to 116, or in other words, the infantile
mortality rate dropped from a decennial mean rate of 179 per 1,000 births to
79, which is the lowest rate ever known in the borough. This decrease was,
however, solely due to meteorological and atmospheric conditions, and not
to any special effort that had been made in the borough. This subject is
discussed more fully under that part of the report which deals with infant
mortality.
