APPENDIX 5 INCOME DECILES


DECILES FOR INCOME ITEMS

Certain income items from the 2011-12 NHS are available expressed in deciles. These are:

• gross weekly cash income;
• gross weekly cash income of household; and,
• gross weekly equivalised cash income of household.

Income deciles are groupings that result from ranking either all households or all persons in the population in ascending order according to income, and then dividing the population into ten equal groups, each comprising approximately 10% of the estimated population. The first decile contains the bottom 10%, the second decile contains the next 10%, and the tenth decile contains the top 10%. Income which is not stated or not known is excluded from the calculation of deciles.

Income deciles for all AHS publications were calculated using the larger Core sample (that is, NHS and NNPAS samples) comprising approximately 33,500 respondents.

The dollar amounts contained in each decile are shown in the following table:
