The United States of America is a large country in North America, often referred to as "the USA", "the US", "the United States", "the United States of America", "the States", or simply "America". 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 home to a 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.
The United States can not be defined solely by television and movies. It is large, complex, and diverse, with several distinct regional identities. Due to the vast distances involved, traveling between regions often means crossing through many different landscapes, climates, and even time zones. Such travel can often be time-consuming and expensive but is often very rewarding.
The United States is made up of many diverse ethnic groups and its culture varies greatly across the vast area of the country and even within cities - a city like New York will have dozens, if not hundreds, of different ethnicities represented within a neighborhood. Despite this difference, there exists a strong sense of national identity and certain predominant cultural traits. Generally, Americans tend to believe strongly in personal responsibility and that an individual determines his or her own success or failure, but it is important to note that there are many exceptions and that a nation as diverse as the United States has literally thousands of distinct cultural traditions. One will find South Carolina in the South to be different culturally from New Hampshire in New England.
