I must admit that I am quite surprised, and even slightly entertained by the discussion about the urban area. Anyway, I will not throw oil at this fire. I like the compact infobox, and if more info needs to be displayed into a table format, then why not create a Paris portal? I would like to correct a slight misconception raised by Captain scarlet: images can actually be added to infoboxes, and that's one thing that I have been doing recently for a number of the French communes. My comments to the current infobox:
 if there is no intercommunality, could we just add "none"?
 why are there 2 figures for the land area? (I guess that it is about the forests areas, but the not does not seem to link anywhere)
 is Paris actually technically a "commune"?
 there is a typo at "Cooridinates"
Otherwise, good job folks.
