Median household income is commonly used to measure the relative prosperity of populations in different geographical locations. It divides households into two equal segments with the first half of households earning less than the median household income and the other half earning more.
Since 2000 household incomes in Australia and New Zealand have been growing rapidly and in 2007 incomes were comparable to those in the United States.
New Zealand and Australia are gradually being economically integrated through a process known as “Closer Economic Relations (CER)”. Their citizens are free to travel, live and work in either country. Information about their relative median household incomes is of interest, especially for those considering migration.
Income data for each state (or territory) has been converted to US dollars using Purchasing Power Parity for private consumption. This is done because it provides a more accurate and stable assessment of the true value of citizens’ incomes in diverse countries.
