Can someone elaborate on the data? For example a small Dutch website has been crawled for Core Web Vitals and stored? Or how does that work?

CrUX data is not based on a crawler but on real Chrome users who agree to share anonymised data with Chrome.

That's what makes it so powerful—these are what your actual users are experiencing (or at least a subset of them using Chrome and meeting the other criteria).

It's also what makes it a bit more complicated, in that the users and their conditions can change (e.g. one week you make get a lot more of X type users, another week less) so your real-world Core Web Vitals numbers can change even if your website doesn't. But that's still what your real users over that period experienced.

See more about the methodology here: https://developer.chrome.com/docs/crux/methodology
