The total population of the Commonwealth of Australia was counted as 4,455,005 – an increase of 681,204 people, 18.05% over the 1901 "Federation" census.

[4] There was a permanent staff of the 'Bureau of Census and Statistics' which consisted of the Statistician (Knibbs) and many assistants, some young men working as clerks as well as a couple of messenger boys.

[6] Collectors had to supply their own transport and cover any associated costs such as fodder and petrol.

Police were used in the days immediately following the census to get travellers, swagmen and campers to provide their information.

[9] Note: All figures are for the census usually resident population count.

At the Census of 3 April 1911, each person was asked to state on a "personal" card, the "Country or Australian State where born," and to state on a "personal" card, and from the replies to this query, taken in conjunction with the other data furnished, the tables contained in Part II.

[14] At the first Australian census in 1911 only those "aboriginal natives" living near European settlements were enumerated, and the main population tables included only those of half or less Aboriginal descent.

Details of those "full-blood" Aborigines enumerated were included in separate tables.

[16] According to these figures it appears that of the 4,455,005 people in Australia on census day (3 April 1911) 4,274,414 were Christians, 36,785 non-Christians, 14,673 are described as indefinite, 10,016 were of no religion, 83,003 objected to state to what faith, if any, they belonged, and the remaining 36,114 were unspecified.
