Jennifer Sciubba is a political demographer and the president and CEO of the Population Reference Bureau, so she’s a pretty good authority on what global data says about falling fertility rates (news flash: they are!). She and Hank talk about why predictions beyond 30 years are just for play, whether we’re reproducing ourselves in other ways apart from procreation, the problems that arise when you have fewer humans, and the dangers of trying to control fertility rates.

Plus, what happened when Gianmarco was booked for an 85-year-old’s birthday party?
