Mean Duration of Life.
\
Hanover Square Sub-District 68.00 years
Mayfair 77.77 „
Belgravia 48.73„
Whole Parish 54.46 „
The mean duration of life in this Parish during the last
12 years has been as follows —
In 1875 it was 46.67 years
„ 1876 „ 47.96 „
„ 1877 „ 49.52 „
„ 1878 „ 48.03 „
„ 1879 „ 48.55 „
„ 1880 „ 58.01 „
„ 1881 „ 50.26 „
„ 1882 „ 52.56 „
„ 1883 „ 55.09 „
„ 1884 „ 53.78 „
„ 1885 „ 56.11 „
„ 1886 „ 54.46 „
So that the mean duration of life in this Parish during
those 12 years has averaged just 51¾ years.
The mean duration of life in London during the last 9
years has been, according to my calculations, as follows :—
In 1878 it was 34.24 years.
„ 1879 „ 34.23 „
„ 1880 „ 35.17 „
„ 1881 „ 35.87 „
„ 1882 „ 36.82 „
„ 1883 „ 37.88 „
„ 1884 „ 38.08 „
„ 1885 „ 39.29 „
„ 1886 „ 39.31 „
Here again, the new and more accurate method of correcting
the death-rate has no doubt made the calculated figure for
the mean duration of life in the Parish lower than it would
have been with the old method of correction. It may very
safely be said, that considering the figures of the last few
years, the average duration of life in this Parish is at present
not far short of 55 years. The remarkable way in which the
mean duration of life in London continues steadily to increase
will be noticed.
