The current U.S.A. population is over 311 million people (311,800,000 in mid-2011) so the United States has the world's third largest population (following China and India).
As the world's population is approximately 6.8 billion, the current United States population represents a mere 4.5% of the world's population so about one in every twenty people on the planet is a resident of the United States of America.
Have a pleasant day.
