In Empty Planet: The Shock of Global Population Decline (Crown Publishing Group, New York, 2019) Darrell Bricker and John Ibbitson argue that population decline will bring many social and economic changes—some good, some bad. They assert that “In three decades, give or take…global population starts to decline.”
Note that their title is a bit misleading. World population will probably rise to over 10 billion before the slow decline would begin.
