populations of all areas are not similarly constituted as regards
the proportions of their sex and age group components.
Consequently he has supplied a correcting or adjusting factor to
all areas with instructions that the Recorded Death Rate should
be multiplied by the factor supplied to ascertain what is known
as the Corrected Death Rate. The object of this is to provide a
true mortality index for comparison purposes, eliminating
variations in mortality which arise as the result of differences
in the age and sex group components of various populations.
The correcting factor for this area is 1.02 and, multiplying
the Recorded Death Rate of 12.00 by this figure, a Corrected
Death Rate of 12.24 is ascertained—a figure which although
higher than the previous year of 10.31 is on a par with the
general death rates used for comparison purposes.
It is again interesting to note that of the 748 deaths, 342
or 46 per cent. occurred in hospitals and institutions outside the
Borough.
Mortality in Age Groups.
| Deaths under 1 year | 41 |
| „ between 1 and 2 years | 4 |
| „ „ 2 „ 5 | 3 |
| „ „ 5 „ 15 | 5 |
| „ „ 15 „ 25 „ | 30 |
| „ „ 25 „ 45 „ | 74 |
| „ 45 „ 65 „ | 227 |
| „ over 65 years of age | 364 |
| Total | 748 |
It will thus be seen that 364 persons dying during the year
—or approximately 49 per cent.—reached the age of 65 or over.
Further analysis of this figure shows the following:—
| Deaths between 65 and 70 years of age | 77 |
| „ „ 70 „ 75 „ | 79 |
| „ „75 „80 „ | 96 |
| „ „80 „ 85 „ | 58 |
| „ „85 „ 90 „ | 35 |
| „ „90 „ 95 „ | 15 |
| „ „95 „ 100 „ | 3 |
| „ over 100 years of age | 1 |
| Total | 364 |
