Shouldn't R0 be independent of N ?

If I have ten times the population, I should not have ten times the R0, correct? Or, ... what am I missing?

This comment is based on the code in the Python notebook.

EDIT:

changed R to R0 in the description and text, realizing I was initially confusing one for the other.
deleted initial context, unnecessary

thanks.
