Turning to Tables IV. and IVa. we find that the corrected
birth-rates were all, as usual, very low, those of the Hanover
Square and Mayfair Sub-Districts being the lowest yet
recorded, while that of the Belgravia Sub-District was
higher than that for 1883, but lower than that of any previous
year, the same being the case for the birth-rate of the
whole Parish; and that the corrected death-rates are also
very low, those of Hanover Square and Belgravia being
lower than those of any previous year except 1883, and the
same being the case with the death-rate of the whole Parish,
while that of Mayfair is rather higher than it has been since
1879. As usual, both the birth-rate and death-rate of
Mayfair are decidedly lower than those of either of the
other two Sub-Districts, those of Belgravia being the
highest.
From the birth-rates and death-rates in Table IVa., I
have calculated the mean duration of life in the Parish and
in each of the Sub-Districts during the year 1884, and
found them as follows:—
Mean Duration of Life.
Hanover Square Sub-District - 62.92 years.
May fair 72.70 „
Belgravia 49.02 „
Whole Parish 53.78 „
The mean duration of life in this Parish during the last
10 years has been as follows:—
In 1875 it was 46.67 years
„ 1876 „ 47.96
„ 1877 „ 49.52 ,
„ 1878 „ 48.03 „
