In addition numbers of new factories have been erected,
and it is known that a considerable number of workers have
been imported and found accommodation within the Borough
boundaries.
However, I am informed that the actual numbers shown
on the electoral registers recently compiled show a marked
diminution and therefore one feels compelled to accept the
official estimate.
BIRTHS.
There were 839 births during the year (416 male and 423
female). Of these 49 were illegitimate (19 male and 30 female).
This figure shows a Birth Rate of 13.43 per 1,000 of the
population. In addition there were 34 stillbirths registered.
DEATHS.
The Registrar-General's official return shows that 632
residents of the Borough died during the year (312 male and
320 female). This figure gives a Death Rate of 10.11 per 1,000
of the estimated population. In a memorandum issued with
the official returns for 1934, the Registrar-General drew
attention to the fact that this rate is unsuitable for the purposes
of comparison with other areas, by reason of the fact that the
populations of all areas are not similarly constituted as regard
the proportions of their sex and age group components.
Consequently he has supplied a correcting or adjusting factor
to all areas with instructions that the Recorded Death Rate
should be multiplied by the factor supplied to ascertain what is
known as the Corrected Death Rate. The object of this is to
provide a true mortality index for comparison purposes,
eliminating variations in mortality which arise as the result of
differences in the age and sex group components of various
populations.
The correcting factor for this area is 1.02 and, multiplying
the Recorded Death Rate of 10.11 by this figure, a Corrected
Death Rate of 10.31 is ascertained—a figure which compares
favourably with London, other Boroughs and England and
Wales as a whole.
It is again interesting to note that of the 632 deaths, 273 or
43 per cent. occurred in hospitals and institutions outside the
Borough.
