Median household income in the Wellington Region, New Zealand

Total household income is derived by taking the sum of the median personal income of all members of the household who are aged 15 years and over.
For categories with small populations the data may not look as expected because of the effect of random rounding.
Median total household income is rounded to the nearest $100.

In our maps, 'home ownership' is defined as the sum of households who own or partly own their usual residence, plus the ones whose dwelling is held in a family trust.

A household is either one person who usually resides alone, or two or more people who usually reside together and share facilities (such as for eating, cooking, or a living area; and bathroom and toilet) in a private dwelling. Included are people who were absent on census night but usually live in a particular dwelling and are members of that household, as long as they were reported as being absent by the reference person on the dwelling form.

This data has been randomly rounded to protect confidentiality.
Figure.NZ calculated percentages based on the 'Total stated' values for each variable.

This time series is irregular. Because the 2011 Census was cancelled after the Canterbury earthquake on 22 February 2011 the gap between this census and the last one is seven years. The change in the data between 2006 and 2013 may be greater than in the usual five-year gap between censuses. Be careful when comparing trends.
