(b) School population: Total on books 16,500; deducting
1,700 for new Estate children, leaving Estate children
14,800. Estimated number 14,500.
(c) Proportion of under 15 to total number: number under
15, 21,550 ; in total of 48,520 gives a proportion of
under 15 to total of 44%.
(d) Population per house : Number of houses in mid-year,
10,900 gives a population per house 4.45.
This distribution then is assumed to hold and from it one
obtains the proportion of children under 15 to the total population,
namely 45%.
Population per House.
At the time of home visiting of children under the Notification
of Births Acts, the number of occupants of the house are recorded.
Excluding the records of houses in which a later birth has occurred,
that is, counting the occupants of any single house at the time only
at the last visit, a total of 5,141 houses gives an average population
of 5.57.
This is the maximum average as it includes the child last
born, which was the reason for the visit and the record. The
minimum average will be not less than this figure minus one for the
deduction of the last birth, i.e., 4.47 per house.
Assuming this is the average content of the remaining 10,000
houses on the Estate the average per house for the entire Estate
will be 1/3 of 5.67 (for the 5.000 houses) + 2/3 of 4.57 (for the
remaining 10,000) =4.90.
This figure is higher than that found to obtain at the last
local census conducted by the London County Council a few years
ago.From the nature of the population, one would expect a
steady increase for a while. The population of the country
increases slightly by the excess of the births over deaths. This
district has a young adult population with a relatively high birth
rate . Further, being deficient in the older-aged population, the
death rate is low. Both these factors tend to increase the natural
growth of the population at a rate exceeding that obtaining in the
country as a whole. That this actually occurs is shown by the
figures of the population per house in different sections of the
Estate. The highest average, namely figures of 5.99, 5.94 and
5.72,were found to occur in those sections completed by 1925, or
