Population un-mixing follows decades of demographic expansion that exceeds a single lifetime

Evidence

Second, from a macro-historical point of view, both expellees and repatriates share a dynamic of global ‘un-mixing’, of rapid ‘contraction’ and concentration after a period of demographic expansion, stretched over several decades or even centuries. Again, migration theory does not provide a common category to account for this fact. Terms like ‘remigration’ or ‘return migration’ do not apply, as in most cases ‘emigration’ and ‘return’ did not occur within the span of a lifetime. In the case of the repatriates, a majority of them did not even have any French ‘ancestry’. — Manuel Borutta and Jan C. Jansen, Vertriebene and Pieds-Noirs in Postwar…, 58

Categorization

• DEFINE: Introduces ‘reflux’/‘un-mixing’ as the category covering contraction migrations and notes most repatriates lacked French ancestry.
• QUESTION: Worth chasing: ‘un-mixing’ suggests these flows are contractions after expansion — does the same reversal dynamic characterize other solidarity movements once expansion conditions end?
