* Weighted data from the National Aboriginal and Torres Strait Islander Health Survey 2004-05 confidentialised unit record file (CURF) [14].

† CI, confidence interval. Proportions are weighted to provide population estimates. Totals are based on those with non-missing data, except for equivalised household income, for which a separate category is shown.

‡ Includes ownership/purchase by any of the dwelling's occupants (not necessarily the respondent) [15,17].

§ n/a, not available.

|| Gross weekly equivalised cash income of household, which takes into account household size and composition, was estimated using the OECD scale [15,17]. Quintiles were determined based on all-Australian figures. That is, the same category boundaries were used for both Indigenous and non-Indigenous participants.

** Food insecurity was based on the response to a question about whether, in the past 12 months, the respondent had run out of food and couldn't afford to buy more [15].

†† SEIFA, Socioeconomic Index for Areas, Index of Relative Disadvantage. SEIFA quintile was based on the 2001 score for the CD of the selected dwelling and is used as a measure of area-level disadvantage [15,17]. Quintiles were determined based on all-Australian figures. That is, the same category boundaries were used for both Indigenous and non-Indigenous respondents.

‡‡ Classified according to the Australian Standard Geographical Classification remoteness classification (based on the ARIA+ index) [15,17].

§§ Out of scope - not included in the survey [14,15].
