Contribution to Population Change by Component
Using the ‘mover-stayer’ data described above for internal migration at territorial authority area level, these maps provide a direct comparison of the contribution of each component across New Zealand’s 67 territorial authority areas for the periods 2001-2006 and 2008-2013.
Key Observations: The 2008-2013 period saw New Zealand experience relatively low international migration compared with the 2001-2006 period. As a result, the proportion of Stayers in each area was generally greater across 2008-2013, as was the proportion ‘not born five years previously’.
Other common points:
- In the majority of cases Stayers account for around two-thirds to three-quarters of each area’s Census population. The percentage of each population categorised as ‘Stayers’ remains remarkably similar over each observed period.
- The percentage of each population categorised as Arrivals was generally lower at the 2013 Census than the 2006 Census. This suggests that people were less likely to move within New Zealand between 2008 and 2013 than between 2001 and 2006.
- The percentage of each population categorised as Overseas five years ago was generally lower at the 2013 Census than the 2006 Census. Reflecting international migration trends, this suggests that people were less likely to move to New Zealand between 2008 and 2013 than between 2001 and 2006.
- The percentage of each population categorised as not born five years ago was generally higher at the 2013 Census than the 2006 Census. This will in part reflect an increase in birth rates and numbers that for most areas began around 2002 and peaked in 2008.
- The main mover origins and destinations of each individual Region and TA are often identical, as they are also across each period, and often account for similar proportions of movers. It would seem that the majority of New Zealand movers move within relatively narrow geographic areas, and that these areas may coincide with labour market regions.
- Prorating the lived elsewhere in New Zealand/not further defined and residence 5 years ago not stated categories (see methodological notes) generally resulted in increasing the Stayer percentage and reducing any net internal migration loss.
