Notes:

The following notes to the table appeared in the original report.

1 The figures for Wards are printed in old face type (e.g. 607) and those for Civil Parishes, where different from Wards, in modern face type (e.g. 607).
2 DEFINITIONS: PRIVATE FAMILY. -- Any person or group of persons included in a separate return as being in separate occupation of any premises or part of premises is treated as a separate family for Census purposes, lodgers being so treated when returned as boarding separately and not otherwise. Private families comprise all such families with the exception of those enumerated in (i) Institutions or (ii) business establishments or boarding houses in which the number of resident trade assistants or resident boarders exceeds the number of members of the employer's or householders family (including private domestic servants).
3 DEFINITIONS: STRUCTURALLY SEPARATE DWELLINGS. -- A structurally separate dwelling has been defined for the Census as any room or set of rooms, intended or used for habitation, having separate access either to the street or to a common landing or staircase. Thus each flat in a block of flats is a separate unit; a private house which has not been structurally subdivided is similarly a single unit whether occupied by one family or by several families. But where a private house has been subdivided into maisonettes or portions, each having its front door opening on to the street or on to a common landing or staircase to which visitors have access, then each such portion is treated as a separate unit.
4 DEFINITIONS: ROOMS. -- For the purposes of the Census, the rooms enumerated are the usual living rooms, including bedrooms and kitchens but excluding sculleries, landings, lobbies, closets, bathrooms, or any warehouse, office, or shop rooms.
5 Areas marked (*) have been created or altered during the 1921-1931 intercensal period; for particulars of such creations or alterations (except those relating to Wards), see Table 4.

This website does not try to provide an exact replica of the original printed census tables, which often had thousands of rows and far more columns than will fit on our web pages. Instead, we let you drill down from national totals to the most detailed data available. The column headings are those that appeared in the original printed report. The numbers presented here, which are the same ones we use to create statistical maps and graphs, come from the census table and have usually been carefully checked.

The system can only hold statistics for units listed in our administrative gazetteer, so some rows from the original table may be missing. Sometimes big low-level units, like urban parishes, were divided between more than one higher-level units, like Registration sub-Districts. This is why some pages will give a higher figure for a lower-level unit: it covers the whole of the lower-level unit, not just the part within the current higher-level unit.
