Norfolk Island is an external territory of Australia located in the Pacific Ocean about 1,600km northeast of Sydney. While the island has been an Australian territory since 1914, in May 2015 legislation came into effect which provided for the Australian Government to assume responsibility for funding and delivering national and state level services for Norfolk Island.
Norfolk Island was re-included in the Australian Census of Population and Housing in 2016. Prior to this, the Norfolk Island administration conducted their own censuses from 1981 to 2011. In the 2021 Census the usual resident population of Norfolk Island was 2,188, an increase from 1,748 people in 2016.
The Census collects information that provides insight into the cultural background of our population. This information includes ancestry, country of birth, country of birth of parents, and languages used at home. Census data enables us to measure these changes over time.
Ancestry data reported for Norfolk Island from the 2021 Census is not comparable with ancestry data reported from Norfolk Island censuses prior to and including 2011 because of the difference in the way the question was asked. The 2011 Norfolk Island Census asked one question relating to ancestry, specifically whether a person was of Pitcairn descent. In contrast, the Australian Census asked respondents to identify up to two ancestries, using either the tick box list provided or by writing in the text fields.
See Understanding ancestry in the Norfolk Island population for further information on the differences between the ancestry questions in the Norfolk Island Census and the Australian Census.
