This is a interesting time waster but it's fun:
There are 299,968,595 people in the United States of America. If everyone in the U.S. lined up single file, the line would stretch around the Earth almost 7 times. That's a lot of people.
The U.S. Census Bureau statistics tell us that there are at least 88,799 different last names and 5,163 different first names in common use in the United States. Some names are more common than others.
