Interstate migration has consistently detracted from population growth in the Northern Territory (NT), with more people leaving the NT than arriving. In the NT, this population loss is usually offset by natural increase (greater births than deaths). However, the COVID-19 pandemic may have resulted in inbound and outbound migration changes. The 2021 Census of Population and Housing was conducted in the midst of COVID-19 pandemic restrictions, including closed borders both domestically and internationally. Analysis of Census data will help to inform migration patterns in the NT observed during this time.
