The Nigerian Podcast Index counted 329 shows. The Airtime directory lists 17 of them, about 5.2 per cent, leaving 312 that the census found and we do not carry. When our discovery process last swept Nigeria specifically, it returned twelve candidates and eight were already in our list. The problem is not that discovery is hard. It is that discovery keeps landing on the same visible shows.
Two days ago we published the uncomfortable shape of our own directory: 88 per cent of it is South African, and that says more about where podcasts have been written down than where they are made. This is the same admission from the other end, and it is sharper.
Nigeria is the one African country with a real podcast census. The Nigerian Podcast Index counted 329 shows and published its method. So for exactly one country on the continent, it is possible to measure a directory against a known denominator rather than against a guess.
Ours does not come out well. We list 17 Nigerian shows. That is 5.2 per cent of what has been counted, and it means 312 shows exist, are known to exist, and are not in our directory.
The more useful finding came from trying to fix it. When we last ran a discovery sweep aimed specifically at Nigeria, it came back with twelve candidate shows. Eight of them were already in our directory. After verification, four were genuinely new: So Nigerian, The How Far Podcast, The Africalypso Podcast and But What Do I Know?. A dedicated hunt through the obvious sources, in the country with the best data on the continent, moved us from thirteen shows to seventeen.
Discovery is not failing to find shows. It keeps finding the same shows, because the same shows are the only ones anybody has indexed.
That two-thirds duplication rate is the actual story. It means the searchable surface of Nigerian podcasting, the charts, the platform pages, the aggregator lists, the shows that get written about, is small and heavily overlapping. Everyone drawing from it arrives at roughly the same few dozen names. The census's other 312 shows are not hiding. They are published, they have feeds, most of them are on Spotify for Creators like three in five Nigerian shows. They simply do not appear in the places anyone looks.
This compounds every other problem we have written about this month. A show that no directory carries does not get discovered by listeners, does not appear in the pitch deck an advertiser reads, and is not in the sample when someone announces what African podcasting sounds like. When a quarter of Nigerian shows go quiet, invisibility is a plausible contributor rather than a coincidence.
The caveats. Our 17 against the census's 329 is not quite like for like: we exclude sermon-only feeds and radio rebroadcasts, and the index does not, so some of the 312 would never qualify for our list. Coverage is also not the only measure of a directory; every entry we carry has been verified by hand, which is slower and produces smaller numbers than scraping. And the census is itself a snapshot from February by a single analyst, not a permanent register.
None of that rescues 5.2 per cent. The honest reading is that our Nigerian coverage is a rounding error against the known total, and that the method which got us here, sweeping the visible sources, has largely exhausted what it can find. Getting to a hundred Nigerian shows means going where the index went: to the hosting platforms directly, feed by feed, rather than to the charts.
That is the work we are committing to next, and we would rather publish the gap than quietly close it. If your show is Nigerian and not on our list, that is our failure and not your obscurity.
