POPULATION.
The estimation of population in a rapidly growing town
such as Ilford presents some difficulty. The rate of progress
varies from year to year according to the rate at which new
houses are being built. Provided that the social character
of a district does not change, the population of the district
is found to alter in proportion to the varying number of
inhabited buildings. A method of estimating the population
founded on this principle has been found to give very
accurate results in the past. I propose to apply this method
as follows:—
At the Census taken in April, 1911, it was found that
there was a nett population of 73,022 persons living in 15,832
inhabited buildings. Excluded from this total are the following
institutions:—
Claybury Asylum with 2,699 persons :
West Ham Asylum with 977 persons :
Dr. Barnardo's Homes with 1,407 persons :
Ilford Isolation Hospital with 83 persons :
It is seen that there was an average population of 4.61
persons per inhabited building.
Now the number of inhabited buildings at the Census
in 1911 was 15,832; the number of uninhabited buildings,
894; the total number, 16,726.
The total number of buildings erected from the time of
the Census in 1911 up to the middle of 1914 was 1,098,
making a total of 17,824 buildings.
I find from enquiry that about 350 buildings were
unoccupied in the middle of 1914, making a nett total of
17,474 inhabited buildings at that time.
Allowing a population of 4.61 per inhabited building we
get 80,555 as estimated population apart from institutions.
