Western Europe is now very diverse with now the Grand children of the first waves of immigrants of the 1940's and 50's growing up in Western European countries and then both intermarrying in and moving from country to country.

Many of the initial wave of immigrants came from colonies to the "mother-country" but many of them were also descendants of immigrants who had moved because of Empire.

Afro-Caribeans, to Britain were the descendants of slaves from West Africa.

East African Asians were the descendants of Indians who had moved from India to East Africa when both were British.

The French took in large populations from North and West Africa.

The Dutch from Indonesia.

Western Europe then gave all citizens of all of Western Europe the right to live and work in any other country of the EU.

The recent change is 2004 the old Eastern Europe joined the EU and gained the right of free movement around the rest of Europe, we have seen mass migration from East to West in search of better jobs and pay causing lots of bad feeling. We have seen problems in the other direction where societies which have been very stable for decades see lots of black and brown faces and some have struggeled with the concept of Chinese-French, African-British, Turkish-German etc.

Give it another couple of decades and they will get used to it.

But in the major cities of Western Europe they are pretty international melting pots.

London is something like 70% white, 10% Indian, 5% Black African, 5% Black Caribean, 5% Chinese or other Asian, and the White portion will include 100,000's of French Poles, Russians etc, Languages in London
