Census - Families by income group by territorial authority 2001, 2006, 2013

Total family income is derived by taking the sum of the median personal incomes of all members aged 15 and over of the family nucleus. This refers to income in the 12 months ending 31 March 2001, 31 March 2006 and 31 March 2013 respectively.

A family nucleus comprises a couple with or without child(ren), or one parent and their child(ren) whose usual residence is in the same household; the children do not have partners or children of their own living in that household. Included are people who were absent on census night but who usually live in a particular dwelling, and are members of a family nucleus in that dwelling, 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. Individual figures may not sum to totals and values for the same data may vary in different tables.
Please note the meshblock-level data has been removed by Figure.NZ to reduce file size.

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.
