I had the privilege of being interviewed by rtve (@rtvenoticias.rtve.es ), Spain’s national public broadcaster, about our research on fertility desire and romantic partnership.

The interview was a live radio show and now it is online (2:15-7:45): www.rtve.es/play/audios/...

Have you heard of the Fire Horse Year?

In Japan, fertility dropped 26% that year & jumped 41% the next — the biggest change in world history since 1950. The reason? A widespread superstition related to the Fire Horse Year.

I just spoke about this in an interview with @financialtimes.com

A study with @ryotamugiyama.bsky.social and @alyceraybould.bsky.social

Supported by @demosocupf.bsky.social @upf.edu @ucl.ac.uk

@iussp.bsky.social, @popassocamerica.bsky.social @populationeu.bsky.social

A press release of our new study in English/Spanish/Catalan has just out. We explain a situation those who do not have any romantic partner in Japan and found that individuals without a romantic partner are more likely to revise their fertility desires downward.

Do you know year of Fire Horse? And do you know the total fertility rate dropped 26% in the last fire horse year in Japan?

My new blog post explains how the superstition changed fertility pattern in the last Fire Horse Years (1906, 1966) in Japan.

2026 will be Fire Horse...

Why is Japan’s fertility rate falling—and what’s really behind it?

We wrote a 10,000+ word guide on it in plain English with data + research insights.

No jargon, just clarity.
