Dear moderator,
I am a statistician and i Suppose that you have not understand the second point : the decrease of Paris percentage was couterbalanced only by the same increase of New York one.A large number of poeple have voted for new York that is to say too that the denominator of the percentage should be increased for all the others candidates (except New york ) due to the increase of new people.
Your explanation is not fair and complete.
Try again !
Thank you
numerator/denominator=ratio or percentage.
The newcoming people voting for new york induce de facto an automatic increase of denominator of each ratio and not only
for Paris one
