Czech linguist Jakub Marián has created another interesting map:
See e.g. the Maltese Independent. The map – which is said to be valid even when the data up to June 2016 are added – shows the dominant source of foreign-born residents in each European country. In other words, the map answers the question "Where did the largest group of aliens who live here come from?"
Sometimes you could expect that most of the European countries will proudly carry the label of an exotic, mostly Muslim, country. But you may see that it's not the case.
The map shows that France, Spain, and the Germanic Scandinavian countries aren't the top exporter of the people in any European country: you won't find these countries anywhere on the map.
Czechia is the top exporter of the people to the brotherly Slovakia while Germany exports the people to Denmark in the North and Austria and Switzerland in the South – problem-free transfers. Italy leads in the people's exports to Belgium while Portugal's people similarly end as winners in Luxembourg.
Black Angola wins in Portugal, Arab Morocco wins in Spain, and Arab Algeria wins in France. The only other top Islamic exporters of people are Syria into Turkey, Turkey into the Netherlands, and (60% Islamic) Albania into Slavic Macedonia and Greece (and Greece is the top exporter into Albania, a mutual exchange). In the rest of the post-Yugoslav countries (Macedonia was mentioned now), Bosnia is the largest exporter of the people, with the exception of Bosnia itself where people born in Croatia win.
In the U.K., the people born in India are at the top. Great Britain seems to have the most faraway source of the non-native population. India used to be their colony – and you may still see that the U.K. is "different" in the character of this immigration from the continental European Western countries.
The U.K. people move to Ireland and Cyprus where they lead the hitparade, Estonia exports to Finland, and Finland exports to Sweden. One may largely interpret the previous sentence as a description of some "Go West" migration from the more Eastern Europe and this is basically an accurate description for all other country pairs I haven't mentioned so far, too.
So Ukraine is the biggest people exporter to Czechia (both Russians and Slovaks lag behind a bit), Poland, Russia, and Moldova. Russia is the largest people exporter to the strip of the three Baltic countries, Belarus, Ukraine, plus Bulgaria, and Romanians top-migrate to Hungary and Italy. I think that with this organization of the pairs, I have memorized the whole map. ;-)
I think that a slight majority of these pairs of nations that define the main migration flows are basically problem-free. This is almost certainly the case of the Germans moving to the neighboring Western countries or Czechs moving to Slovakia. But I would include even the Ukrainians moving to Czechia (and probably elsewhere). Not everyone loves them but they're in no way considered a major problem for the country.
It's hard to say whether the Poles in Germany are a "problem". Germans aren't "allowed" to point out even problems with Muslim rapists, let alone with the Polish plumbers, so officially there's certainly no problem with the Poles going to Germany. I guess that Turkey would beat Poland in Germany if 2nd generation were counted.
Some of us sometimes get obsessed with the Islamic migration etc. But we should keep these processes in the proper perspective. There is still a lot of less game-changing migration that numerically wins. I think that only a relatively small fraction of Europe is sitting on the trend towards the significant Islamization – a trend that could realistically turn these countries into countries with Muslim majorities later in this century. This problematic description doesn't seem to apply to most of Europe.
Off-topic but politics: The New York Times informs about the assault of the Kurdish socialist militias on their Turkish police oppressors. It's grown into a tough conflict but I want to mention that The New York Times classify this news from Kurdistan or East Turkey as news from "Europe".
It seems that it's politically correct to say in the U.S. that every violent savage in Eurasia and Africa is a "European" but I am sorry, folks in the NYT, you're just full of šit. According to any geographic or cultural definition of Europe, Kurdistan or East Turkey simply don't belong to Europe but to Asia. If you want to learn several things at once, be aware that: Not just Kurdistan but any country or region named -*istan is a part of Asia. That's why the terms *istan are used as satirical insults. For example, an unpopular Czech politician may be turning our country into Czechistan.
The New York Times inkspillers are turning their island to Manhattistan, too.
