I was thinking the same, should be one in four Americans or one in four people. Even then I think one in four is a bit high. I couldn't name another person, except maybe the maintenance workers, in my building who carry a flashlight or knife, and those maintenance men only carry it because it is part of their toolbox not as and EDC or PSK item. I've met a few guys who carry leathermans and a couple with Mag solitaires or small led lights on their keychain but mostly because someone bought their dad a present for Christmas or Birthday, no thought into preparedness. I certainly haven't met one in four, one in 10 at best with a single item that could be used in an emergency.
