The survey included every house in the Borough occupied, or of a
suitable type for occupation, by the working classes, and excluded
Metropolitan Police estates, certain Crown properties, public houses and
those premises occupied wholly by shopkeepers, medical practitioners
and dentists, etc.
For the purpose of this part of the survey, each child under 10 years
of age was counted as a half-person.
The enumeration showed (1) the families which were overcrowded,
irrespective of the sizes of the rooms occupied; (2) the families which
were not overcrowded; and (3) the doubtful cases of overcrowding, i.e.,
those families which were not overcrowded when regard was had solely
to the number of rooms occupied in accordance with Table I, but might
be overcrowded when Table II, which takes into account the sizes of the
rooms, was applied. These doubtful cases were ascertained by comparison
of the information obtained with the following Table :—
Number of rooms
in letting.
Maximum permitted
number (Table I).

In applying this Table it was assumed that if the "equivalent
number" of persons (i.e., counting each child under 10 as half a person)
in a dwelling was less than the reduced permitted number, such a dwelling
would not be overcrowded on the standard of Table II. If, however,
the equivalent number of persons was equal to, or in excess of, the reduced
permitted number and the family was not overcrowded on the standard
of Table I, the case was considered doubtful.
The analysis of the information obtained as a result of the preliminary
survey revealed 3,138 definitely overcrowded families, 29,337 definitely
not overcrowded families and 8,733 possibly overcrowded families
occupying 7,711 houses.
