Description

Internal migration is the change of people’s usual residence within the national boundaries of a country.

For usual residence one year ago, it relates to people aged one year and over who are usually resident in New Zealand at the time of the 2018 Census (6 March 2018) but lived at a different usual residence one year earlier (6 March 2017).

For usual residence five years ago, it relates to people aged five years and over who are usually resident in New Zealand at the time of the 2018 Census (6 March 2018) but lived at a different residence five years earlier (5 March 2013). For the 2018 Census, this is not derived from a census question but by linking of 2018 Census respondents (usual residence in 2018) to their 2013 Census record (usual residence in 2013).

Excluded are people who did not specify a usual New Zealand address for either reference date; or those who were classified as having ‘no fixed abode’, had an ‘overseas’ address, or a ‘New Zealand not further defined’ address.
