Composition
Main article: Economy of the United States by sector See also: Technological and industrial history of the United States and Agriculture in the United StatesMost of the U.S. economy is composed of services.
The United States is the world's largest manufacturer, with a 2009 industrial output of US$2.33 trillion. Its manufacturing output is greater than of Germany, France, India, and Brazil combined. Main industries include petroleum, steel, automobiles, construction machinery, aerospace, agricultural machinery, telecommunications, chemicals, electronics, food processing, consumer goods, lumber, and mining. The US leads the world in airplane manufacturing, which represents a large portion of US industrial output. American companies such as Boeing, Cessna (see: Textron), Lockheed Martin (see: Skunk Works), and General Dynamics produce a vast majority of the world's civilian and military aircraft in factories stretching across the United States.
The manufacturing sector of the U.S. economy has experienced substantial job losses over the past several years. In January 2004, the number of such jobs stood at 14.3 million, down by 3.0 million jobs, or 17.5 percent, since July 2000 and about 5.2 million since the historical peak in 1979. Employment in manufacturing was its lowest since July 1950. The number of steel workers fell from 500,000 in 1980 to 224,000 in 2000.
The U.S. produces approximately 18% of the world's manufacturing output, a number that has declined as other nations developed competitive manufacturing industries. The job loss during this continual volume growth is the result of multiple factors including increased productivity, trade, and secular economic trends. In addition, growth in telecommunications, pharmaceuticals, aircraft, heavy machinery and other industries along with declines in low end, low skill industries such as clothing, toys, and other simple manufacturing have resulted in U.S. jobs being more highly skilled and better paying. There has been much debate within the United States on the decline in manufacturing jobs are related to American Unions and lower foreign wages.
Although agriculture comprises less than two percent of the economy, the United States is a net exporter of food. With vast tracts of temperate arable land, technologically advanced agribusiness, and agricultural subsidies, the United States controls almost half of world grain exports. Products include wheat, corn, other grains, fruits, vegetables, cotton; beef, pork, poultry, dairy products; forest products; fish.

Famous quotes containing the word composition:
“There was not a grain of poetry in the whole composition of Lord Fawn, and poetry was what her very soul craved;Mpoetry, together with houses, champagne, jewels, and admiration.”
—Anthony Trollope (1815–1882)
“When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nor diminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.”
—David Hume (1711–1776)
“There is singularly nothing that makes a difference a difference in beginning and in the middle and in ending except that each generation has something different at which they are all looking. By this I mean so simply that anybody knows it that composition is the difference which makes each and all of them then different from other generations and this is what makes everything different otherwise they are all alike and everybody knows it because everybody says it.”
—Gertrude Stein (1874–1946)
