It covers an area of about 24,480,000 square kilometres (9,450,000 sq mi), or about 4.8% of the planet's surface. As of July 2002, its population was estimated at more than 514,000,000. It is the third largest continent in area, after Asia and Africa, and is fourth in population after Asia, Africa, and Europe.

Etymology

A number of theories exist regarding the naming of North and South America. The most widely recognized is that they are named after Amerigo Vespucci, who was the first European to suggest that the Americas were not the East Indies, but a New World, previously undiscovered by Europeans. The second and less generally accepted is that the continents are named after an English merchant named Richard Amerike from Bristol, who is believed to have financed John Cabot's voyage of discovery from England to Newfoundland in 1497. A third theory that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of 'Amairick'.

Geography

North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America. North America's only land connection is to South America at the narrow Isthmus of Panama. (For geopolitical reasons, all of Panama – including the segment east of the Panama Canal in the isthmus – is often considered a part of North America alone.) According to some authorities, North America begins not at the Isthmus of Panama but at the Isthmus of Tehuantepec, with the intervening region called Central America (or Middle America if the Caribbean is included) and resting on the Caribbean Plate.
