Transcript: We’re Not Having Enough Kids – It’s A Disaster: Stephen J. Shaw on TRIGGERnometry

Read the full transcript of data scientist, demographer, and filmmaker Stephen J. Shaw’s interview on TRIGGERnometry Podcast with hosts Konstantin Kisin and Francis Foster on “The Fertility Crisis: Understanding the Birth Gap”, September 17, 2025.

Welcome Back to TRIGGERnometry

KONSTANTIN KISIN: Stephen Shaw, welcome back to TRIGGERnometry. Great to have you on.

STEPHEN J. SHAW: Thanks for the invite.

KONSTANTIN KISIN: Well, you obviously, we talked with you, I think it was last year, about your documentary Birth Gap, talking about the fertility crisis across the world now, not just the Western world, but across the Western world, which is basically the fact we’re not having enough children to replace the population as we have now. We talked about many of the challenges that poses.

I think the stat that really stood out for a lot of people from that interview is in Japan, where you live, more adult nappies are sold than baby nappies. So there’s more nappies for people who in the final stages of life than for babies. And this is a thing that is increasingly being replicated around the world and you now have some new data and you’ve done a lot more research into this.

So talk to us about where the world is in respect to all of that. Just remind people and then what have you discovered about why it is that way?

The Stroller Statistics and Growing Awareness

STEPHEN J. SHAW: I’ll add just one thing about nappies. I believe it’s not the case for strollers as well. I think stroller sales for pets are now outstripping strollers for kids. That’s in South Korea and I believe it’s true in Japan too. So things aren’t getting better anywhere.

And you’re right, what’s happening in the Far East, I’m still based in Tokyo, is absolutely playing out. So it was two years ago I was here and at that time, I would say fertility came into the mainstream press once or twice a year.
