Seems it could usefully apply to states, counties, cities too: basically any Location.
And better as a number rather than text, for consistency and arithmetic.

If the use case is comparison/analytics, then we’d need to have a set of triples all from the same source and the same date.

Hey! Yeah, u are right about states and cities, but since there is only Country as entity atm, I decided to point it out as a constraint.
On the one hand, I agree with u on analytics issues, on the other Im not sure we can prevent using UN data or official national statistics data. Quite a difficult questions tbh. Anyway, thanks a lot for the feedback
