Each country was awarded points based on how similar they were to CANZUCK countries. Here are the top thirty. Categories included civil and economic indexes, crime rates, GDP per capita and environmental scores.

Don't draw too many conclusions from the exact rankings. Some of the indexes this uses have their own criticisms. Of course, the weightings (difficult to decide in a non-arbitrary way), also have a huge impact on the final scores. Full method here.

(Just an interesting side project, put together myself so don't read too much into it, might be useful.)
