Driven by an unrelenting collapse in fertility, family structures and living arrangements heretofore imagined only in science fiction novels will become commonplace, unremarkable features of everyday life.
Human beings have no collective memory of depopulation. Overall global numbers last declined about 700 years ago, in the wake of the bubonic plague that tore through much of Eurasia.
