North America is technically defined as consisting of three regions: North America, Central America, and the Caribbean. Under those three regions are a total of 23 sovereign states including the United States of America, which makes the US dollar the most popular currency used in the continent, followed by the Canadian Dollar and the Mexican Peso.
Outside the US, the East Caribbean Dollar is the most commonly used currency, circulating in seven territories including Antigua and Barbuda, Dominica, Granada, Montserrat, Saint Lucia, Saint Kitts and Nevis, and Saint Vincent and Grenadines. It is represented by either the regular dollar sign ($) or s EC$ to distinguish it from the US dollar. Meanwhile, there are also Non-Dollar Currencies in North America, used primarily by Central American and Caribbean nations. These currencies include the Cuban peso, Guatemalan Quetzal, Convertible Peso, Haitian Gourde, Panamanian Balboa, Netherlands Antillean Guilder and Honduran Lempira.
Because of the fact that Canada, Mexico, and the United States have substantial and dynamic economic systems, North America has the largest economy in the world.
