That's assuming that city people do the same things as rural people, and the only difference is whether they own a car and a house. City people earn much more money which they spend more freely and use to do more things, which require orders of magnitude more resources, even if they may be slightly more efficient when traveling within city limits (just think about the multiple flights per year every urbanite I know takes, versus the one or two per decade everyone else takes).
