Stunted Growth

The tide of population is turning. Across the globe, countries’ populations are shrinking and aging, and most are ill-prepared not prepared for a “childless, elderly future,” writes Steve LeVine.

Population growth in Africa alone will keep the global population soaring past 11 billion this century. But everywhere else, by 2050 a quarter of the world’s population will be over 60, 48 countries or areas will have fewer people, and 35 countries will have less than 2 workers per retired person.

As life expectancy climbs, a dearth of young, robust workers forces us to confront 2 controversial solutions: rethinking migration policies, and embracing robots.
