International Comparisons:

International comparisons: 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: income inequality, cigarette smoking and road deaths, where more recent data is available, and indigenous language speakers, for which OECD comparisons are not made.

To make international comparisons for some indicators, we have used a slightly different outcome measure to that used in the main social report. Outcome measures for cigarette smoking, educational attainment of the adult population, tertiary participation, market income per person, income inequality, voter turnout and internet access differ from those used to report the outcomes of the general New Zealand population in The Social Report 2006.
