when is a "city" a city?

Surprisingly, I am having a hard time finding the answer to this.

So, Is there a standard in OSM for what qualifies as a city,town,village, etc?
Is it by population?
is it by official city boundry?

Also, this might be handy for some people:

I entered “City” in the wiki’s search box and got this:
Key:place

thanks,

so my home “city” is being a bit over ambitious…

population is approx 10,000 just barely makes the rank of Town.

lol

Yes, many cities in America and Canada will struggle to make the grade. OSM still has some anglocentric definitions. :slight_smile:

That said 10,000 is low by world standards.
