CHAPTER 1

The UNITED STATES OF AMERICA (THE USA)

The United States of America (also called the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south.

At 3.79 million square miles (9.83 million km2) and with over 312 million people, the United States is the third or fourth largest country by total area and the third largest by both 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 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's seventh-highest.

Indigenous peoples descended from forebears who migrated from Asia 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 4, 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 17, 1787. Its ratification the following year made the states part of a single republic with a strong central government. The Bill of Rights, comprising ten constitutional amendments guaranteeing many fundamental civil rights and freedoms, was ratified in 1791 [4, p. 39].

Through the 19th century, the United States displaced native tribes, acquired the Louisiana territory from France, Florida from Spain, part of the Oregon Country from the United Kingdom, Alta California and New Mexico from Mexico, and Alaska from Russia, and annexed the Republic of Texas and the Republic of Hawaii. Disputes between the agrarian South and industrial North over the expansion of the institution of slavery and states' rights provoked the Civil War of the 1860s. 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 1870s, its 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 41% of global military spending, and is a leading economic, political, and cultural force in the world [4, p. 57].

THE AMERICAN ECONOMY

2.1 The description of the American economy

The American economy is a dynamic, free-market system that is constantly evolving out of the choices and decisions made by millions of citizens who play multiple, often overlapping roles as consumers, producers, investors and voters. The United States is generally described as a mixed economy, which is to say that even though the great majority of productive resources are privately owned, the federal government does play an important part in the marketplace.

By any standard, the American economy that has evolved over less than 250 years has been immensely successful. With less than 5 percent of the world's population, the United States in the early 1990s produced about 25 percent of the world's output. The U.S. economy is more than twice as large as the next largest economy, that of Japan. By conventional measures, U.S. productivity and standard of living remain among the highest in the industrial world - although other nations have experienced higher rates of grown in recent decades.

The economy of the United States is the world's largest national economy. Its nominal GDP was estimated to be over $15 trillion in 2011, approximately a quarter of nominal global GDP. The European Union has a larger collective economy, but is not a single nation. Its GDP at purchasing power parity was also the largest in the world, approximately a fifth of global GDP at purchasing power parity. The U.S. economy also maintains a very high level of output. In 2011, it was estimated to have a per capita GDP (PPP) of $48,147, the 7th highest in the world, thus making U.S. one of the world's wealthiest nations. The U.S. is the largest trading nation in the world. Its three largest trading partners as of 2010 are Canada, China and Mexico.

The economy of the United States is a mixed economy and has maintained a stable overall GDP growth rate, a moderate unemployment rate, and high levels of research and capital investment. It has been the world's largest national economy (not including colonial empires) since at
