Ok, I took a look at the subrankins and I think they either aren't measuring for the best country to live in (although idk wtf else the best country is supposed to mean) or they have some fucked up idea of what that entails. Apparently they have ten subrankings and the overall ranking is based on how well a country ranks on them. Now here's the deal... Quality of life in a country only accounts for 13.88% of the score. Read that again. Sure there are other important things, such as Agility (measures how well a country can adapt to shit going on in the world and accounts for 14.18%), Entrepeneurship and Open for business (important for the economy and thus for the future of the country, 14.16% and 9.42%) and Social purpose (human rights etc. 12.23%), but there is also a whole lot of stuff that probably doesn't give a lot of comfort to people living there if the above things aren't in check. Movers, Power, Cultural influence and Heritage together total in 25.18% of the score if my math checks out. That's ridiculously much for things that at the end of the day are relatively insignificant in terms of how good a life people living in a country can live.
