The "factor for correction" for this District is i.045. The
corrected rate is obtained by multiplying the crude or recorded
death.rate by this factor.
The corrected death.rate was 7.3, a decrease of .5 per i,000
on the rate of the preceding year, and 2 3 below the average
corrected rate for the previous i0 years. This is the lowest
death.rate on record for this District.
As compared with the previous year, there was a considerable
increase in the rate of deaths from Measles, Influenza, and
Diseases of the Respiratory Organs; and a very marked increase
in that from Bright's disease—while there was a decided decrease
in the rate of deaths from Scarlet Fever and Infantile Diarrhoea'
In explanation of the above, it is very probable that the
inclement weather experienced last year played an important part
both in the increase of mortality in the diseases above mentioned,
and also in the entire absence of deaths from Diarrhoea, to which
a cold wet summer is unfavourable.
Infantile Mortality.—There were 25 deaths of infants
under i year of age, which gives an infantile death.rate of 36'3
per i,000 births registered, as against 56.l in the preceding year,
72.7 in i907, and i04 9 in i906. The average rate for the i0
years i899.i908, was 9ii.
This is by far the lowest infantile death.rate on record in
this District, and is i9'8 below that of the previous year, which
was the previous lowest rate on record for the District, and 54 8
below the average rate of the previous i0 years. This continually
falling infantile death.rate is in itself very satisfactory, and
although it is in part no doubt due to the constantly improving
sanitation of the district, and to the fact that the very poor and
ignorant form but a very small proportion of the population,
which is chiefly a residential one, yet it must be borne in mind
that the birth.rate is also steadily declining, and that there is, of
course, a close relation between the two. Moreover, the cold and
wet weather of last summer was very unfavourable to infantile
diarrhoea, which in normal summers is an important cause of
mortality from this disease.
In Table V. are set forth the causes of deaths of infants
under one year of age, in weeks and months.
The infantile death.rate of North Southgate was i8 7, and
that of South Southgate 44.3.
The infantile death.rate in England and Wales was i09,
which is ii per i,000 below the rate in i908, the lowest rate on
record. Compared with the previous i0 years, the rate of
infantile mortality in i909 showed a decrease of 29 per i,000.
