Considering where to live?
An interesting comparison between a nation's average yearly temperature and their inequality-adjusted Human Development Index. The Human Development Index is a composite of statistics on a nation's life expectancy, education and income per capita. The ideal place to live should have high HDI and a warm average temperature.
In general, the colder the nation the higher the human development index score given by the UN. As an outlier, Australia looks like the place to live.
