The United States of America, also known simply as the United States, America or the States, and often abbreviated to USA or U.S., is a federal constitutional republic made up by fifty states and a federal district (District of Columbia). The nation is located mostly in North America, however, the State of Hawaii is located in the mid-pacific. In L.A. Noire, the set for every mission is the city of Los Angeles, California which is located in the United States.
At 3.79 million square miles (9.83 million km2) and with over 308 million people, the United States is the third or fourth largest country by total area, and the third largest both by land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2009 GDP of $14.3 trillion (24% of nominal global GDP and 20% of global GDP at purchasing power parity).
Indigenous peoples have inhabited what is now the mainland United States for many thousands of years. This Native American population was greatly reduced by disease and warfare after European contact. The United States was founded by thirteen British colonies located along the Atlantic seaboard. On July 4th, 1776, they issued the Declaration of Independence, which proclaimed their right to self-determination and their establishment of a cooperative union. The rebellious states defeated the British Empire in the American Revolution, the first successful colonial war of independence. The current United States Constitution was adopted on September 17th, 1787; its ratification the following year made the states part of a single republic with a strong federal government. The Bill of Rights, comprising ten constitutional amendments guaranteeing many fundamental civil rights and freedoms, was ratified in 1791.
In the 19th century, the United States acquired land from France, Spain, the United Kingdom, Mexico, and Russia, and annexed the Republic of Texas and the Republic of Hawaii. Disputes between the agrarian South and industrial North over states' rights and the expansion of the institution of slavery provoked the American Civil War of the 1860's. The North's victory prevented a permanent split of the country and led to the end of legal slavery in the United States. By the 1870's, the national economy was the world's largest. The Spanish–American War and World War I confirmed the country's status as a military power. It emerged from World War II as the first country with nuclear weapons and a permanent member of the United Nations Security Council. The end of the Cold War and the dissolution of the Soviet Union left the United States as the sole superpower. The country accounts for 43% of global military spending and is a leading economic, political, and cultural force in the world.
