Population.—The population of the Borough at the middle
of 1937 is estimated by the Registrar General to be 156,460. The
estimated population at the middle of 1936 was originally 145,000,
this figure being adjusted by the Registrar to 146,300 following
the alteration of the Borough boundaries on the 1st April, 1937,
when West Twyford was again included in the area. The net
increase of population during the twelve months is therefore
10,160, this being the largest annual increase ever recorded.
The new Housing Estate of the London County Council on the site
of the old Cuckoo Schools at Hanwell is largely responsible for
this increase in population as the majority of the new residents
moved into it from the County of London during the period
embraced in the report.
In view of the alteration of the Borough boundaries on the
1st April the statistics supplied by the Registrar General are
composite figures combining the records for the first portion of
the year, prior to the change of boundaries, with those for the
enlarged area for the remaining portion of the year. The Registrar
has therefore supplied a modified estimate of population specially
designed for use with the composite records of births, deaths
and notifiable diseases. This modified estimate of population
is 156,070 and this figure has been used in the calculation of the
statistics contained in the report.
