Construction of Table 1.
Column 1.
In 1926 in England and Wales, 34% of the total deaths
occurred below the age of 45. The actual number of deaths
(corrected) in this district below 45 in 1927 was 223. Given
a similar distribution of population as for the country as a
whole, this would represent a total of 650 deaths.
The deaths occurring in the age group 25—44 formed 10.9%
of the total for the Country. In this area 74 deaths occurred
at these ages. This would give a total number of deaths, if
the age distribution were normal, of 680. This figure is probably
the more accurate, as the age group 15—25 is probably not
normally represented in this district.
Column 1 is made up by taking the total of 660 deaths and
dividing the figure into the various age groups to show the
ages at which the deaths occur, the distribution amongst these
age groups being that holding for the entire country in 1926.
This column therefore represents the number of deaths
which would have occurred at each age group had each age
group been represented in the district in the same ratio as the
group 25—44 is represented; with the proviso, of course, that
the rate of dying in each group is the same as that holding^ for
England and Wales.
Column 2.
15,000 is taken as that portion of the population which has
a normal age group distribution. This number dying at the same
rate as holds for England and Wales (death rate in 1926,11.6 per
1,000 living) would yield 175 deaths. The column shows the
manner of distribution of these deaths in age groups if the
deaths occurred in those groups at the same rate as for the
country as a whole.
Column 3.
This is the actual number of deaths recorded as' occurring
at each of the age groups.
Column 4.
This shows the distribution of deaths of the theoretical population
which would have supplied 660 deaths, after deduction
of those deaths occurring in the 15,000 population, i.e.,
column 1 minus column 2.
