Definition and measure
Disposable income, or RGNDI, measures the purchasing power of New Zealanders. Higher RGNDI per person shows that a nation has a greater capacity to deliver a better quality of life and standard of living to the population.
RGNDI measures the total income, adjusted for inflation, that New Zealand residents receive, not only from domestic production but also from the net income flows with the rest of the world.
Technical changes since 2010
RGNDI is now expressed in 2009/10 prices instead of 1995/96 prices. Additional information about this change is available from Preview of 2014 national accounts improvements.
The starting date for the disposable income indicator is 1992, not 1988, which it was in Key findings on New Zealand's progress using a sustainable development approach: 2010. This reflects the methodology change in 1991 to use ‘resident population’ instead of ‘de facto population’ in national population estimates.
De facto population estimates measure the number of people present in an area at a point in time, including people who live elsewhere (such as overseas). The resident population makes an allowance for residents who are undercounted (missed) and overcounted (counted more than once), or temporarily overseas on census night.
The RGNDI per person series is now calculated from 1992 onwards using the concept of resident population.
