Geography

Climate

The climate is diverse in the United States, but many parts have a continental climate, often with hot summers and great variations in temperature during a year.

The west coast has a maritime climate, with relatively mild winters. There is however a big difference between the northern and southern parts of the west cost. The northern parts receive a lot of precipitation, especially during the fall. The southern and central parts of California have a typical Mediterranean climate, with very little precipitation and sun most of the year. One of the warmest areas of the world, Death Valley, is located in Southern California.

East of the Rocky Mountains are the Great Plains. This area consists of large steppes, having a unique climate. Moist winds from the Gulf of Mexico meet cold wind from the north, which leads to a lot of changing weather. The Great Plains are known for their tornadoes, and for snow and hail storms. The Midwest is known for short springs and falls, and often long winters.

The climate is mostly warm in the southern states along the Gulf, and there is hardly any real winter. The south often sees hurricanes in the fall, causing great damage.

The climate is more varied on the east coast and in the Appalachian Mountains, but a common denominator is that these areas often receive lot of precipitation. The climate of the east coast is to a lesser degree than he west coast affected by the ocean, so that is has a typical continental climate. The northeastern parts of the United States have a lot of snow in the winter, including the coastal areas.

History

Thirteen of 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) and the Great Depression of the 1930s. Buoyed by Allied victories in World Wars I and II and the end of the Cold War in 1991, the U.S. remains the world's most powerful nation-state. The economy is marked by steady growth, low unemployment and inflation, rapid advances in technology, and a very wide range of incomes, compared to other nation-states.

Economy

The economy of the United States is based upon capitalism, with elements of a mixed economy. The U.S. is the world's economical powerhouse, and the standard of living is mostly high. The median income is $46,326 per household. The wealth is somewhat unevenly distributed; the top 20% have a household median income of $91,705, the lowest 20% have $19,178.

Private enterprises account for the biggest part of the U.S. Gross Domestic Product, but the public sector is also substantial, consisting of 35% of the GDP. Government regulations are not as extensive as in many other western countries. The labor market is flexible, and social welfare services are more limited than in Europe. Social spending is increasing, and the cost of federal programs such as Medicare and Medicaid is growing.

The central bank of the United States is the Federal Reserve System. The Federal Reserve is independent from the government, and Congress does not interfere with its policies.

Demographics

The population of the United States reached 300 million in 2006. The population is highly heterogeneous, and consists of many ethnic groups. The majority of Americans are whites of European descent. The largest group is German-Americans; with Irish-Americans, English-Americans coming next. The largest minority groups in the United States is African-Americans.

The current demographic trend is that the Hispanic population is growing, mostly because of immigration from Mexico and other Latin American countries.

Language

English is the de facto national language, even though there is no official language at the federal level. Applicants for U.S. citizenship have to pass an English literacy test.

About 82% of the population speak nothing but English at home. The second most commons language is Spanish. 29 states have made English their official language. Three states have other additional languages used by the state governments; Hawaiian in Hawaii, French in Louisiana, and Spanish in New Mexico.

Religion

Religion is an integrated part in American daily life, and society is not as secularized as in Europe. Six out of ten Americans feel that their faith plays a very important role in their lives.

The U.S. Census Bureau does not audit the religious beliefs of the American population; the figures for religious beliefs in the united States are therefore uncertain. The CIA World Factbook estimate that 90% of Americans are believers. Christianity is the largest religion, with protestants making the biggest group (52%). 24% of the population are catholics.
