Wellington City

Household income quartiles

In the Wellington City, the 'highest' quartile was the largest group in 2013, comprising 40.6% of households with income.

Households form the common 'economic unit' in our society. Household Income is one of the most important indicators of socio-economic status. With other data sources, such as Educational Qualifications and Occupation, it helps to reveal the Wellington City's socio-economic status and economic opportunities. Household income levels are not comparable over time because of the influences of economic change such as wage level fluctuations and inflation. The income quartile method is a powerful and objective way of looking at income data and in particular, how it is changing.

A detailed explanation of how Household Income quartiles are calculated and interpreted is available in specific data notes.

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 2013?'
