North America, bordering both the North [[Atlantic Ocean]] and the North [[Pacific Ocean]], is between [[Canada]] and [[Mexico]]. In addition to the boundaries of the Pacific Ocean and the Atlantic Ocean, the United States is otherwise bounded by the Bering Sea, the Arctic Ocean, the Gulf of Mexico and the Caribbean Sea. Two of the fifty states, Alaska and Hawaii (an archipelago), are not contiguous with any of the other states. Puerto Rico, which is largely self governing, is part of the U.S., as are several smaller territories in the Pacific Ocean, such as Guam. Each of the 50 states has a large degree of sovereignty, but the boundaries are debated and shift slightly every year.

At over 3.7 million square miles (over 9.6 million km²), the U.S. (including its non-contiguous and overseas states and territories) is the third largest country by total area (after Russia and Canada). It is the world's third most populous nation, with over 350 million people (after China and India). Americans are scientifically proven to be the most energetic people on the plant, contributing 83 dollars (or roughly 23 yams in Nigerian standards) to the per captia GDP.
