1905, 1906 and 1909. The age period from 15-25 was responsible for only 161
deaths, or 20 below the average of the preceding ten years and it was only as
good on two previous occasions in twenty years. Again, at the age period
25-35 there were only 232 deaths registered, or 59 below the return of the
years 1901-10, and the return was smaller than any recorded during the twenty
years 1891-1910. The return for the age period 35-45 was very good also, as
it was 25 below the average of the preceding ten years, and was better on
only three occasions in twenty years. Between 45-55 there was also a
comparatively small mortality, for the returns only recorded 486 deaths, or 27
below the average of the preceding ten years, and it has only been so low on
three occasions in twenty years. Among persons aged from 55-65 there were
591 deaths, or 18 below the average of the ten years 1901-10, which, with two
exceptions, was the lowest return in twenty years. Hence onward at each
period of life there was an increased mortality, for the 673 registered deaths
between the ages of 65-75 were 24 above the average of the ten years 1901-10 ;
while those of persons between 75-85, 482 in number, were 8 in excess of the
average ; and those of persons 85 and upwards 149 in number, were 11 above it.
This increase in the number of persons dying at the later periods of life,
which was commented on in the Medical Officer of Health's report for 1909,
is without doubt due to the larger number of old persons now living in the
Borough, owing to the change in the age incidence of the population discussed
in an earlier part of this report.
Mortality in the Sub - Districts.—The number of deaths in the
seven sub-districts varied from 399 in Tufnell, to 1,136 in Islington South East;
while the death-rates ranged from 11.89 per 1,000 in Tufnell, to 17 0 in
Barnsbury.
Tufnell Sub-District.—There were 399 deaths registered, which is the
smallest number known since the district was formed. It is 25 less than in the
preceding year, and 66 less than the average of the past nine years. The
death-rate (11'89) is also the lowest since the formation of the sub-district, as
well as the lowest for any of the sub-districts during the year.
Upper Holloway,—599 deaths, equal to a death-rate of 16.1 per
1,000 of the population, were registered. This mortality is the highest recorded
since 1902, when 605 occurred, and was partly due to an increase in the deaths
under a year old.
