Life is complex. It resists one-dimensional explanations. So our World Residence Index evaluates nations across eleven dimensions (yes, our index goes up to 11). The index takes into account economic factors such as personal income tax rate, per capita GDP and unemployment rate. It reflects population density, life expectancy, infant mortality rate and an ephemeral quality we call lifestyle. And for good measure it evaluates each nation’s freedom level. Not surprisingly, the top five in overall ranking are Switzerland, Andorra, Monaco, Bermuda and the Cayman Islands. While at the bottom you’ll find North Korea along with a number of authoritarian African regimes. On taxes, many nations have a zero percent personal rate. While the highest – 65% – is found in Sweden. 2 The highest per capita GDP – $179,478 – is found in Liechtenstein, followed by Monaco, Qatar, Luxembourg and Singapore. Want to live long? Monaco’s life expectance is over 89 years – though we don’t know whether or how that would apply to those relocating there at various life stages.
