greater Manchester for the period 1891-3. It is now possible to compare on these lines the
London mortality in the decennium 1891-1900 with that obtaining in the decennium 1881-90, and
for this purpose the following table* has been used, showing the mean future lifetime of males
and females in certain age-groups, calculated from the Ex and columns of the life table for
London 1881-90, published in my annual report for the year 1893.
|Age groups.||Males.||Females.||Age groups.||Males.||Females.|
|25—||31.04||34.51||85 and upwards||2.75||2.85|
In the following table the mean annual number of deaths occurring in the decennium
1891-1900 is compared with the annual number of deaths which would have occurred had the
death-rates of the decennium 1881-90 been maintained in 1891-1900, and the annual number of
lives gained or lost in the latter period at each age-group is shown. The figures in the last column
of the table express this gain or loss in terms of "life capital," these figures being obtained by
applying the mean future lifetime figures given in Table I. to the number of lives gained or lost
at each age-group.
|Age groups.||Deaths calculated according to mean rates of 1881-90.||Mean deaths occurring in the decennium 1891-1900.||Mean annual gain (+) or loss (-) of lives in the decennium 1891-1900 by fluctuations of mortality.||Mean annual gain ( + ) or loss (-) of " life capital" in the decennium 1891-1900 by fluctuations of mortality.|
|85 and upwards||485||452||+33||+91|
|5—||1,313||1,190||+ 123||+ 6,480|
|85 and upwards||1,022||1,003||+19||+54|
* The method employed in the calculation of this table is shown in more detail in my annual report for the year 1894, page 10.
