@hazelnot @delroth It falls under the *municipality* of Rotterdam, yes, but that is absolutely *not* the same thing as being part of Rotterdam's metro/urban area. Municipalities are primarily government-administrative boundaries, not planning or cultural boundaries.

@joepie91 @delroth I agree, I'm just reinforcing the idea that the Sony people had no idea what they're doing, cause OSM's metro area tags refer strictly to the official administrative boundaries as far as I know

@hazelnot @joepie91 FWIW I don't think the Sony CSL research uses the OSM metro areas, it uses either the OECD FAUs or the GHS UCDB when available according to the paper.

But both are equally terrible. The GHS UCDB for Rotterdam even includes The Hague... 🤦‍♂️

@delroth @joepie91 💀

@delroth @hazelnot lmfao

@hazelnot @delroth (Which means that some municipalities are comically large and aren't necessarily named after any one of the towns or cities therein, because they tend to get scaled by "population count at which government and admin can be efficiently conducted" rather than anything else, so many small mostly-unrelated towns are likely to group together into a municipality for example)

@joepie91 @delroth Interesting, in Romania a town only becomes part of a municipality if it's adjacent or basically-adjacent to the pre-existing municipality (which in Romanian simply refers to a larger/more important city) and is generally considered to be a suburb or part of it

@hazelnot @delroth The adjacency does typically exist here as well, and it does often historically center around larger places (at least larger at the time) but at a certain scale and certain amount of municipality merges, that doesn't have very much relevance or resemblance left :p
