Expat Explorer [hsbc.com] provides a visual overview of how 25 countries are ranked according to the opinions of those best placed to compare the quality of living in different countries: people living abroad.
The interactive, geo-located bubble world map is based on a large survey of about 4,000 expats conducted in 2010. Individual criteria can be selected under the broad categories of economic wellbeing, lifestyle/experience and the wellbeing of children to contrast the performance of different countries. Pairs of countries can be compared side by side in detail, in addition to some links to relevant information such as specific tax and country guides.
