Bhutan didn't release any model yet as far as I know, if the level of care government give to people actual happiness is what are supposed to be concerned about here.

Among over countries that are consistent being on top on gross national happiness are Finland, Denmark, Iceland, Switzerland, and the Netherlands. Among them the current abilities to release open models is observable.

USA unfortunately continues to fall down quickly in World Happiness Report rank, and that's not because many other countries made great progresses.
