context_page_description: North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be described as a northern subcontinent of the Americas, or America, in models that use fewer than seven continents. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean.
  North America covers an area of about 24,709,000 square kilometers, about 16.5% of the Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included.
  North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge approximately 40,000 to 17,000 years ago. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The classic stage spans roughly the 6th to 13th centuries.
context_section_description: Economically, Canada and the United States are the wealthiest and most developed nations in the continent, followed by Mexico, a newly industrialized country. The countries of Central America and the Caribbean are at various levels of economic and human development. For example, small Caribbean island-nations, such as Barbados, Trinidad and Tobago, and Antigua and Barbuda, have a higher GDP (PPP) per capita than Mexico due to their smaller populations. Panama and Costa Rica have a significantly higher Human Development Index and GDP than the rest of the Central American nations. Additionally, despite Greenland's vast resources in oil and minerals, much of them remain untapped, and the island is economically dependent on fishing, tourism, and subsidies from Denmark. Nevertheless, the island is highly developed.
  Demographically, North America is ethnically diverse. Its three main groups are Caucasians, Mestizos and Blacks. There is a significant minority of Indigenous Americans and Asians among other less numerous groups.
