1934, and, taking into consideration the extensive
building operations which became active during 1934, the
total of dwellings arrived at was 14,380. The average
number of persons per house at the time of the Census
of 1931 was 4.2, but experience shows that there has been
a diminution in the figure so that a comparative estimate
of population at the end of 1934 may be taken as 57,520.
A more important factor than numbers is the age and
sex distribution of the population. The Registrar
General gives an adjusting factor of .97 when consideration
is given to the various mortality rates for purposes of
comparison with other areas. Thus Bromley in 1934 had
a crude death rate of 9.8 per 1,000 of the population based
on the Registrar General's figure of population. This
death rate is only comparable with death rates of other
areas if multiplied by the correcting factor .97.
Bromley's comparable death rate is thus 9.5 after due
regard has been given to age and sex distribution.
II.—VITAL STATISTICS.
Births.
Birth rate for 1934 is 13.3, a rise compared with the
rate of 12.3 for 1933.

Due allowance has been made for inward and outward
transfers of births. During 1934 779 births actually
occurred in Bromley, but some of these were extra-district
children, and the figure does not necessarily compare with
the Registrar General's return which relates to registered
births, it being remembered that births need not be
registered until the 42 days' grace is about to lapse,
whereas births must be notified to a local authority within
36 hours of occurrence.
