Buildings, Dwellings, Rooms and Families.
Note.—The following table contains analyses of (1) the buildings and (2) the structurally separate dwellings of each area.
In the upper part of each section the several classes (Groups I-V) are analysed both in the left-hand columns (a-c) in respect of their characteristics as buildings, and in the right-hand
'columns (f-p) in respect of the dwellings which they comprise.
In the lower part of each table the subjects of analysis on the left and right respectively are different; on the left the " buildings " analysis is continued in respect of an expanded classification
of one of the five groups ; while on the right the analysis according to dwellings is continued in respect of certain selected classes of private family occupations.
BUILDINGS (left-hand columns (a-c) ).—In the enumeration of buildings, a building has generally been regarded as a structure wholly detached or separated from another by a vertical
party wall. A block of flats would be one building though there might be one or more separate flats on each floor.
The allocation of buildings among the several classes shown in Column (e) is based on the descriptions furnished by the local enumerators. The varieties of type encountered in the buildings
enumerated have, however, inevitably given rise to some difference of practice on the part of enumerators in describing borderline cases ; and the numbers of buildings assigned to the several
classes in Column (e) should therefore be regarded as approximate.
The classification differs from that adopted in 1911 in the following respects :—
(a) Structurally divided private houses are separately shown for the first time, with a view to affording an indication of the extent to which houses originally built for the occupation
of single families have been structurally divided to provide separate and independent accommodation for two or more families. There is evidence, in the returns, that it has not always
been possible for enumerators to distinguish between buildings originally erected to comprise, e.g., maisonettes and those subsequently converted for the purpose.
(b) Inns and Public Houses in which the business of the establishment is primarily that of retailing liquors are classed with Shops (Group IV) instead of with Hotels (Group V), which
are thus limited in the table to those of a residential character.
STRUCTURALLY SEPARATE DWELLINGS (right-hand columns (f-p) ).—Above the "total" line dwellings are classified according to the type of building in which they occur, while
below, the " total " line the same premises are classified according to the number of families enumerated within them.
Dwellings " Vacant on Census night " include those imoccupied through the temporary absence of the usual occupier as well as those without a tenant.
The total rooms in dwellings occupied by private families as shown in the following table is usually slightly in excess of the total rooms occupied (Tables pages 105 and 107), owing to the fact
that in certain dwellings inhabited bv two or more families, part of the dwelling was unoccupied on Census night.
