Does anyone even listen to creationists these days?

And much later - think of Israel after WWII.

If you want to go that route now, think of regional and international movement and migration of labor today: hundreds of millions in China alone, to say nothing of Eastern Europe-Central Asia, Latin America to North America, internally in the United States, Western Europe as we all know...

However, crucially, by this time the migration of massive and cohesive social units (e.g. "tribes") is over.

With rather few exceptions, whole nations are not v'pokhode gatoviye.

That said, out of interest what are the major exceptions from the past century? That is, general immigration patterns or sporadic refugee movements aren't really counted here.

1. Israel
2. South Vietnam-United States
3. Soviet Jewry-United States/Israel
4. Ethnic cleansing of Prussia

Sorry couldn't help this one: v pokhod gotovyie.
But I'm sure even in ancient times it was not the WHOLE nations that were on the move. There were some individuals (or perhaps even groups) that chose to stay (see Avari "The Silmarillion") or turned back at an early stage.

Look, you got me - there's a whole can of worms on cultural identity and group membership that I wanted to avoid opening up, so I used a 'quick and easy' shorthand.

A more precise and sociologically-neutral way to put it would be:

Whole communities, or large parts of them, no longer travel cohesively (i.e. constituting a sociopolitical unit) from an origination point to settle, permanently or otherwise, at some other point. A community here can be supralocal, e.g. in the sense of the Nordic settlers of Iceland.

Actually, from that point of view Israel/Soviet Jewry is an interesting case, since with Israel you had many local communities loosely-connected by shared traditions and a nascent Zionism converging on one point in order to undertake a project of forming a new "nation". Of course, if you're a hard-core Zionist that analysis would be tendentious, but really a broader Jewish identity existed only in a relatively-limited number of intellectuals and political activists, even as recently as a century ago. Similar with the Vietnamese case.
