Yields for # of Citizens in Capital?

[679x]

Wondering how to give yields to the Capital based on the number of citizens it has. Can this be done in xml, and if so, how? I want to use this for a custom civ.

For example, 15 citizens in the Capital gives 15 of a certain yield.

Thanks in advance.

I dont think it can be done in xml, at least there are modifiers or even effect types, requirements or collections that relate so something like that.

What you could do is add +1of that yield to any tile in that city, that would have a similar effect (since #cititens = #workedTiles, disregarsing spezialist)

Its not as elegant as +1 for every citizen would be and you cant do something like
+1 for every 2 citizens that way, but it archieves the same stats
