The Americas refers to the combined continents of North America and South America. The Americas have about 1.002 billion inhabitants and span over 16.43 million square miles. The Americas are comprised of 35 countries, including some of the world's largest countries.
The United States is the largest country by population, with an estimated 331 million residents across the 50 states. This is followed by Brazil, with about 212 million, and Mexico, with its 128 million residents. The largest cities in the Americas (Mexico City, New York, Los Angeles, Sao Paulo, and Rio de Janeiro) are also in these countries – each has more than ten million residents.
Although the United States is the most populous country in the Americas, it is not the largest by area. Canada is the largest single country by total area (and the second-largest in the world, after Russia), yet has a much smaller population than the United States, with 37.7 million inhabitants – not many more than the South American country of Peru (32.9 million). Other South American countries with more than ten million residents include Cuba (11.3 million), Ecuador (17.6 million), and Chile (19.1 million).
A few countries in the Americas are comparatively tiny and, interestingly, these countries are only geographically American. They include the French-controlled archipelago of Saint Pierre and Miquelon in the northwestern Atlantic Ocean near the Newfoundland and Labrador province of Canada (6,342 inhabitants), the Caribbean island and British Overseas Territory of Montserrat (5,203 residents), and the Falkland Islands, another British Overseas Territory situated in the South Atlantic, with its population of just 2,922 inhabitants. The smallest independent nation in the Americas is Saint Kitts and Nevis, home to about 53,000 people.
