I think it’s been several years in a row now Nordic countries have been rated the happiest in the world.

Those studies tend to be heavily Euro-centric.

Some of the happiest countries on earth are in East Asia. Bhutan, in particular, is the happiest country you've never heard about. Vietnam and Singapore also tend to rate very high. Bolivia also tends to punch well above its weight class.

But it should be noted that the Nordic states have historically been very far removed from war. With the Ukraine/Russia conflict, Fins are significantly more unhappy than they've been in prior generations. I don't think you can blame that on their domestic policy or their economic model. As more refugees are forced through Europe in an effort to flee conflicts in Armenia and police crackdowns in Hungary and industrial sabotage through the Baltic Sea, happiness in the region is plummeting.
