Definitions and data sources
The definitions of the measures used for each indicator, the reference years the data comes from and the data sources for the international comparisons are detailed below. The majority of data for the Australian and New Zealand comparisons are from the same sources as the OECD data. The exceptions are: indigenous language speakers, adult literacy (prose and numeracy) and satisfaction with work-life balance, where OECD comparisons are not made.
For some indicators we have used a slightly different outcome measure to that used in the main Social Report to enable valid international comparisons. Outcome measures for cigarette smoking, potentially hazardous drinking, educational attainment of the adult population, tertiary participation, market income per person, income inequality, voter turnout, indigenous language speakers and internet access differ from those used to report the outcomes of the general New Zealand population in The Social Report 2009.
