Just to establish my nit-picking credentials
, 1911 was not written up by the enumerators in the way that the earlier censuses were; they just completed Enumerators' Summary Books (RG 78) with a single line per address, naming heads of households only. The reason for this was that the number-crunching could now be done by punch-card operators working directly from the household schedules.
The schedules were kept this time because they contained information that was not in the summary books, whereas in earlier years the Enumeration Books duplicated everything that was in the schedules (in theory!), so the schedules were disposed of once the statistics were abstracted.
