A lot of these actually make a lot of sense. All of these countries make it incredibly hard to integrate into society as a foreigner either because of domestic policy or straight up the language barrier.

In the case of Tunisia, it’s the most liberal Arab country, which is remarkably close to France because of colonialism. Many Arabs wouldn’t want to move to such a place. I don’t think Tunisian Arabic would be the barrier there.

Polish is fucking difficult to pronounce with its 4 and 5 consonant clusters (if I had to guess, most languages max out at 3), and it’s not found anywhere else in the world because Poland didn’t colonize anywhere. They were lucky to get their own country if you look into their history.

Armenia is incredibly socially, religiously, and linguistically dissimilar to everywhere around it. Good luck wanting to move there; 2/3’s of ethnic Armenians live outside the country.

Egypt is the most surprising, because it was colonized and bothered by both the British and French, but it doesn’t have that diversity anymore?

Jordan is a theocratic strong monarchy. Makes sense that non-Jordanese wouldn’t move there.

Bangladeshi people were packed into the country with the partition of India. It’s super ethnically dissimilar to Burma and India. The partition really amplified that.
