United States of America

is a large country in North America, often referred to as the "USA", the "US", the "United States", "America", or simply "the States". Home to the world's third-largest population, with over 318 million people, it includes both densely populated cities with sprawling suburbs and vast, uninhabited natural areas.

With its history of mass immigration dating from the 17th century, it is a "melting pot" of cultures from around the world and plays a dominant role in the world's cultural landscape. It's famous for its wide array of popular tourist destinations, ranging from the skyscrapers of Manhattan and Chicago, to the natural wonders of Yellowstone and Alaska, to the warm, sunny beaches of Florida, Hawaii and Southern California.
