Australian diaspora
The ratio of expatriate Australians in 2005 was 2.8 Australian-born people aged 15 years or over per 100 Australian born people aged 15 years and over within Australia. This ratio is much lower than many other countries in the OECD – the highest ratios in 2005 were for Ireland (29 Irish-born people aged 15 years and over in other OECD countries for every 100 in Ireland) and for New Zealand (19 per 100). The Australian ratio was higher than that of the United States (less than one person in other OECD countries per 100 USA-born within the USA).
