I saw this on Reddit, and having the data to hand, I thought I'd replicate it:

Interesting. Inner London surprised me, it’s remarkably similar to the peak central Dublin number but the curve is completely unlike the other European cities.

If they're centering on the City of London, maybe not that surprising. The Square Mile is famously almost completely empty of residents.
