Planet Earth is made up of about 200 countries. We are the only nation in the world that has more guns than people. That's no small thing because we are the third largest country in the world. China, for instance, has 4.9 guns per 100 people. We have 112 guns per 100 people. No other country is even close. China's population is over four times larger than ours, but we have almost 23 times more guns than they do.
