Country Profile: United States.

The US economy is the largest and most technologically powerful economy in the world, with an estimated gross domestic product (GDP) of $ 15,940,000,000,000 as of 2012, and second only to the European Union (EU) which consists of organization of 28 countries across the European continent.

The United States is located in the northern part of America, bordering both the North Atlantic Ocean and the North Pacific Ocean, between Canada and Mexico. With more than 300 million people, the United States is the third largest country by total area, and third largest by population. America has been often compared with a “melting pot,” because it welcomes people from many different countries, races, and religions. No other place in the world has such a diverse population The American society is one of the most fascinating multicultural mosaics.

:: Background of USA ::

Britain’s American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added to the original 13 as the nation expanded across the North American continent and acquired a number of overseas possessions. The two most traumatic experiences in the nation’s history were the Civil War (1861-65), in which a northern Union of states defeated a secessionist Confederacy of 11 southern slave states, and the Great Depression of the 1930s, an economic downturn during which about a quarter of the labor force lost its jobs. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world’s most powerful nation state. The economy is marked by steady growth, low unemployment and inflation, and rapid advances in technology.
