Well, nothing you'd ever notice. Now, it may well every so slightly push the Earth in the opposite direction. If someone had a superduper sensor that was capable of measuring teensy deviations to the Earth's center of gravity, then perhaps it could be measured. But in real life even WITH such a super measuring device, there are so many natural perturbations to the Earth that are due to so much heavier objects than all the people in the U.S., that the Earth is constantly bumping here and there teensy amounts, so one could not really see the people-jumping-induced Earth-bump because of all the other Earth-bumping constantly occurring (due to, for example, constant magma fluctuations inside the Earth). Its worth a try, though. How about....NOW!
