The concept of “race” as defined in the US is not used in Europe to begin with.
Instead often times what is used is “ethnicity” and even that typically boils down to one’s “origin” and doesn’t take skin color into account.
A lot of European countries prohibit the government from registering skin color, ethnicity, religion etc. out of fear of a repeat of the 1940s.
So you won’t find US-style self-report questions on government forms w/r/t “race” or “ethnicity”.
In fact many go as far as limiting themselves to “citizen” and “non-citizen”, with the exception of immigration services maintaining the necessary information until naturalization of course.
So according to American race definitions most people in Europe will be white, but that doesn’t say much about diversity.
In fact the US definition of White is very broad [0]:
> White. A person having origins in any of the original peoples of Europe, the Middle East, or North Africa. It includes people who indicate their race as "White" or report responses such as German, Irish, English, Italian, Lebanese, and Egyptian. The category also includes groups such as Polish, French, Iranian, Slavic, Cajun, Chaldean, etc.
So for example people from Morocco, Turkey and countries like Iraq and Iran (arguably some of the bigger sources of non-European immigrants to Europe) would be considered “White” implying a lack of diversity, even though there are significant cultural differences between those people and, say, native Germans.
Take a look at Switzerland with four different official languages (five if you include English for many official settings), something not found in the US.
I’ll make sure to let India know that they’re not diverse despite their 23 official native languages and their massive religious divisions.
You’re basically trying to define “diverse” as “amorphous immigrant melting pot”, a society that only exists in the new world where the native population was nearly wiped out.
There is no need to be condescending. Plenty of visibly white people living in a given European country are immigrants. There are flows of people within the EU as well, it’s a big place with a lot of different countries. Quantifying cultural differences is a bit of a fool’s game, but to me it’s not obvious that e.g. Poles or Hungarians are much closer to Spaniards than Moroccans are to the French. Skin colour is just an indication of actual diversity, which includes many other factors.
Poles, Hungarians and Spaniards share a thousand-long common history of being part of Christian Europe, under Roman Christianity. That was the leading and unifying cultural force in Europe up until the XX century (with common philosophy, Latin as the lingua franca, obviously with shared religious beliefs etc.). Moroccans and the French don't have anything that ties them that strongly.
> Poles, Hungarians and Spaniards share a thousand-long common history of being part of Christian Europe, under Roman Christianity
Not at all. That's a mirage in which some people want to believe.
Spain went through the gothic kingdoms, the emirate of Granada, the Reconquista, the Habsburg dynasty, to name a few. Poland saw nothing of that, and was not even part of the Roman Empire in the first place. They went through various wars and conquests with theirs own neighbours, some of the various bits of the Holy Roman Empire, the various baltic and Russian states, and Sweden, but there is almost no overlap with what was going on in Spain. Hungary was a very fringe frontier province in the Roman Empire and the cultural consequences are very different. And again, they were in very different situations, being much closer to the Ottoman Empire for a while and having to deal with the various bits of what is now Romania. Russia is a European country, but again the local culture looks very different.
On the other hand, Spain has a couple of centuries of history in common with North Africa. Ties between Morocco, Algeria, and Tunisia on one side and France on the other are strong because of the shared history and the number of binational individuals and families. This is the same everywhere: countries have strong ties with their neighbours, and this does not stop at the EU's boundaries.
Even the supposedly close religious beliefs created a deep chasm in most of Europe. Large regions of Europe are muslim, there always has been a Jewish minority across the whole continent, and even amongst Christians, how many wars fo religions were fought over the centuries? Europe makes no sense from an ethnic point of view. It is a collection of very diverse people even though there are some cultural and historical aspects in common, and a belief that the future is better if we stop fighting each other. This is why European nationalism is not a thing.
