Number of podcasts worldwideJapan total population
As Japan's population quietly declined, the number of podcasts worldwide exploded in precisely the opposite direction, growing from tens of thousands to over five million. The -0.9716 correlation suggests that for every Japanese citizen who ceased to exist, several podcast hosts began recording.
Japan's population has been falling since 2010. Global podcast numbers grew from roughly 500,000 in 2014 to over 5 million by 2023. The two trends share no mechanism.
Japan's demographic decline and the podcast explosion are both real and both significant, but they belong to entirely different stories.
