One death occurred on the District Railway at Brompton, and
another in a cab in Mortimer Street, Marylebone.
The total number of deaths belonging to the district is 687,
which corresponds to a death-rate of 13.2 per 1,000 inhabitants.
Another correction is necessary before a comparison can be
instituted between this district and neighbouring ones. This correction
is dependent upon the sex distribution and the age constitution of a
district. Females live longer than males, and though there is a preponderance
of females over males in Acton, the death of males exceeded
those of females by 11. Three hundred and forty-nine males
and 338 female deaths occurred last year. If the sex distribution has
not altered since the Census the death-rate last year among males was
14.8 per 1,000, and among females 11.8.
A more important factor is the age-constitution of a population.
The tendency to death is greater among persons living at the extremes
of life—among infants and old people. The ages at death last year
were as follows:—
Under 1 year. 1 to 5. 5 to 15. 15 to 25. 25 to 65. Over 65.
201 91 26 19 194 156
In order to neutralise the errors in death-rate arising from sex
and age-constitution, the Registrar-General has devised a method by
which they can be corrected. This method is based upon the deathrate
of each sex at different ages throughout England and Wales, and
by this means series of factors are obtained, by which the recorded
death-rates of different towns can be multiplied, so as to make them
comparable with that of England and Wales and with each other.
The figures by which the recorded or crude death-rate should be
multiplied, in order to correct for variations of sex and age distribution,
is called the factor for correction for the particular district; and
when the recorded death-rate is multiplied by the factor for correction,
the result is the corrected death rate for that district.
The factor for correction for Acton is 1.04240, so that if the
recorded death-rate. 13.2, be multiplied by this figure, the corrected
death-rate is 13.7.
