My husband and I built an airplane, and we definitely use more fuel when we load the plane with more "stuff."
OTOH, I'm sure there are other factors that are even *more* important to the total consumption of fuel than Americans' weight. (c: Trucking increased amounts of consumer goods to support our increased population size would have to be factored in as well (just as one example). I'm not a traffic management specialist, but I would expect that decreased family size probably balances individual weight gains. I don't weigh "a 10 year old child" more than my 1960s counterpart. GRIN. Since there are never more than four of us in a vehicle, and all four grandparents' families would have routinely hauled 8 or 10 people in a vehicle, the weight was probably similar. LOL!
A statistician is someone who is skilled at drawing a precise line from an unwarranted assumption to a foregone conclusion.
