What is our individual income? (Individual income quartiles)
Derived from the Census question, "From all sources of income identified, what will the total income be that you got yourself, before tax or anything was taken out of it, in the 12 months that will end on 31 March 2006?"
Relates only to persons aged 15 years or more.
Individual income groups are not comparable over time because of the influences of economic change such as wage level fluctuations and inflation. The income quartile method has been adopted as the most objective method of comparing change in the income profile of a community over time. The income quartile method assumes an even distribution within each income group. Quartiles are calculated from New Zealand individual income data.
|Individual income quartiles||Annual income range|
|Lowest group||$0 to $11,397||$0 to $8,903||$0 to $7,689|
|Medium lowest||$11,398 to $24,402||$8,904 to $18,544||$7,690 to $15,603|
|Medium highest||$24,402 to $42,449||$18,544 to $34,732||$15,603 to $29,318|
|Highest group||$42,449 and over||$34,732 and over||$29,318 and over|

Individual income quartiles look at the distribution of incomes in Wellington City relative to New Zealand. Quartiles split the total population into four equal parts for the benchmark area. The table shows the number and proportion of individuals in Wellington City falling into each segment for the benchmark area.
The table gives a clear picture of where individual incomes in Wellington City sit relative to New Zealand. For New Zealand, 25% of persons fall into each category. If, for example, Wellington City has 30% in the top category and only 20% in the lowest, this indicates that Wellington City has proportionally more higher-income individuals and less lower-income individuals.
Income quartiles allow us to compare relative income-earning capabilities across time. Analysis of Oriental Bay's income statistics compared to Wellington City's income statistics shows that there was higher proportion of persons in the highest income quartile, and a lower proportion in the lowest income quartile.
The most significant change in Oriental Bay's income statistics between 2001 and 2006 was in the Highest group quartile which showed an increase of 80 persons.
