The 1901 census was taken the night of 31 March 1901.

Census enumerators were assigned a specific area to cover and distributed a schedule to every household in that area before census night. The following day they were collected, checked and copied into an enumerator's book. The local registrar checked them and sent them to the Census Office and the original schedules were destroyed.
