I checked your link. It says the exact opposite of what you claim.

The second list says - Sweden Ethnic Fractionalization : 0.060000

US EthnicFractionalization: 0.490100

So it says America is 8 times more diverse than Sweden.

Sounds about right. That makes Sweden a lot more homogenous than the US.

The first list is really screwed: it lists Italy and China as among the least diverse - which is rubbish.

That’s because it only includes linguistic diversity- not ethnic diversity. So Sicilians and Milanese are grouped together, as are Han and Tibetans.

Latin America becomes much less diverse, because the many ethnicities speak Spanish, etc.

Look at how undiverse Cuba is!

America has a large number of different cultures, ethnicities and religions, but to get a decent job you need to English.

Consider immigrants: https://en.wikipedia.org/wiki/List_of_sovereign_states_and_d...

My link shows that there is a bigger share of immigrants in Sweden (19%) than in US (14%).

I think cultural diversity weighs more here than skin color.

the largest nordic population is sweden, which is less than 10% the population of the US. it is also ethnically significantly more homogenous than the US, which by your own standard is dizzyingly diverse ('white' contains dozens of ethnicities, along with regional and class subsets and period of integration). assuming that the same policies work for everybody in all circumstances is willful blindness.

Have you been to swedis cities lately? It's diverse.

i do not doubt that there art parts of sweden with significant diversity; it still pales in comparison with america, one of the most diverse nations in history
