Among sovereign states in North America, Barbados has the highest population density. The small Caribbean island nation has roughly 650 to 660 people per square kilometre, depending on the population and land-area estimates used.
Barbados covers about 430 square kilometres and has a population of roughly 280,000. That combination makes it far denser than larger North American countries such as Canada, Mexico, and the United States. Its population is concentrated heavily along the coastal and urbanized parts of the island, especially around Bridgetown.
The wording “among sovereign states” matters. North America includes Caribbean countries as well as Central American and mainland states, and some dependent territories can have different rankings. Barbados is also sometimes confused with nearby island nations such as Grenada, Saint Lucia, and Trinidad and Tobago, but each has a lower national population density.
