U.S. Economy
industry accounted for about 11.1 percent of the overall annual value
added by manufacturing. Texas and Louisiana are leaders in chemical
manufacturing. The petroleum and natural gas produced and refined in both
states are basic raw materials used in manufacturing many chemical
products.
Industrial machinery accounted for 10.7 percent of the yearly value added
by manufacture. Industrial machinery includes engines, farm equipment,
various kinds of construction machinery, computers, and refrigeration
equipment. California led all states in the annual value added by
industrial machinery, followed by Illinois, Ohio, and Michigan.
Factories in the United States build millions of computers, and the
United States occupies second place in the world in the production of
electronic components (semiconductors, microprocessors, and computer
equipment). Electronic equipment accounted for 10.5 percent of the yearly
value added by manufacturing, and it was one of the fastest growing
manufacturing sectors during the 1990s; production of electronics and
electric equipment increased by 77 percent from 1987 to 1994. High-
technology research and production facilities have developed in the
Silicon Valley of California, south of San Francisco; the area
surrounding Boston; the Research Triangle of Raleigh, Chapel Hill, and
Durham in North Carolina; and the area around Austin, Texas. In addition,
the United States has world leadership in the development and production
of computer software. Leading software producers are located in areas
around Seattle, Washington; Boston, Massachusetts; and San Francisco,
California.
Food processing accounted for about 10.2 percent of the overall annual
value added by manufacturing. Food processing is an important industry in
several states noted for the production of food crops and livestock, or
both. California has a large fruit- and vegetable-processing industry.
Meat-packing is important to agriculture in Illinois and dairy processing
is a large industry in Wisconsin.
Transportation equipment includes passenger cars, trucks, airplanes,
space vehicles, ships and boats, and railroad equipment. This category
accounted for 10.1 percent of the yearly value added by manufacturing.
Michigan, with its huge automobile industry, is a leading producer of
transportation equipment.
The manufacture of fabricated metal and primary metal is concentrated in
the nation’s industrial core region. Iron ore from the Lake Superior
district, plus that imported from Canada and other countries, and
Appalachian coal are the basis for a large iron and steel industry.
Pennsylvania, Ohio, Indiana, Illinois, and Michigan are leading states in
the value of primary metal output. The fabricated metal industry, which
includes the manufacture of cans and other containers, hardware, and
metal forgings and stampings, is important in the same states. The
primary metals industry of these states provides the basic raw materials,
especially steel, that are used in making metal products.
Printing and publishing is a widespread industry, with newspapers
published throughout the country. New York, with its book-publishing
industry, is the leading state, but California, Illinois, and
Pennsylvania also have sizable printing and publishing industries.
The manufacture of paper products is important in several states,
particularly those with large timber resources, especially softwood trees
used to make most paper. The manufacture of paper and paperboard
contributes significantly to the economies of Wisconsin, Alabama,
Georgia, Washington, New York, Maine, and Pennsylvania.
Other major U.S. manufactures include textiles, clothing, precision
instruments, lumber, furniture, tobacco products, leather goods, and
stone, clay, and glass items.
B2 Energy Production
The energy to power the nation's economy—to provide fuels for its
vehicles and furnaces and electricity for its machinery and appliances—is
derived primarily from petroleum, natural gas, and coal. Measured in
terms of heat-producing capacity (British thermal units, or Btu),
petroleum provides 39 percent of the total energy consumed in the United
States. It supplies nearly all of the energy used to power the nation’s
transportation system and heats millions of houses and factories.
Natural gas is the source of 24 percent of the energy consumed. Many
industrial plants use natural gas for heat and power, and several million
households burn it for heating and cooking. Coal provides 22 percent of
the energy consumed. Its major uses are in the generation of electricity,
which uses more than three-fourths of all the coal consumed, and in the
manufacture of steel.
Waterpower generates 4 to 5 percent of the nation’s energy, and nuclear
power supplies about 10 percent. Both are employed mainly to produce
electricity for residential and industrial use. Nuclear energy has been
viewed as an important alternative to expensive petroleum and natural
gas, but its development has proceeded somewhat more slowly than
originally anticipated. People are reluctant to live near nuclear plants
for fear of a radiation-releasing accident. Another obstacle to the
expansion of nuclear power use is that it is very expensive to dispose of
radioactive material used to power the plants. These nuclear fuel
materials remain radioactive for thousands of years and pose health risks
if they are not properly contained.
Some 33 percent of the energy consumed in the United States is used in
the generation of electricity. In 1999 the nation’s generating plants had
a total installed capacity of 728,259 megawatts and produced 3.62
trillion kilowatt-hours of electricity. Coal is the most common fuel used
by electric power plants, and 57 percent of the nation’s yearly
electricity is generated in coal-fired plants. The states producing the
most coal-generated electricity are Ohio, Texas, Indiana, Pennsylvania,
Illinois, West Virginia, Kentucky, and Georgia.
Natural gas accounts for 9 percent of the electricity produced, and
refined petroleum for 2 percent. The states producing the most
electricity from natural gas are Texas and California. Refined petroleum
is especially important in Florida, New York, and Massachusetts. The
leading producers of hydroelectricity are Washington, Oregon, New York,
and California. Illinois, Pennsylvania, South Carolina, and California
have the largest nuclear power industries.
Petroleum is a key resource for an American lifestyle based on extensive
use of private automobiles and trucks for commerce and businesses. Since
1947, when the United States became a net importer of oil, annual
domestic production has not been enough to meet the demands of the highly
mobile American society.
In 1970 domestic crude-oil production reached a record high of 3.5
billion barrels, but this had to be supplemented by imports amounting to
12 percent of the nation’s overall crude oil supply. Most Americans were
unaware of the dependence of the country on foreign petroleum until an
oil embargo imposed by some Middle Eastern nations in 1973 and 1974 led
to government price ceilings for gasoline and other energy products,
which in turn led to shortages. In 1973 the nation imported about one-
fourth of its total supply of crude oil. Imports continued to rise until
1977, when about half of the crude and refined oil supply was imported.
Imports then declined for a time, largely because energy-conservation
measures were introduced and because other domestic energy sources such
as coal were used increasingly. As of 1997, however, 47 percent of the
crude oil needs of the United States were met by net imports. Energy
Supply, World.
The United States consumes 25 percent of the world’s energy, far more
than any other country, despite having less than 5 percent of the world’s
population. The United States also produces a disproportionate share of
the world’s total output of goods and services, which is the main reason
the nation consumes so much energy. In addition, the U.S. population is
spread over a larger area than are the populations in many other
industrialized nations, such as Japan and the countries of Western
Europe. This lower population density in the United States results in a
greater consumption of energy for transportation, as truck, trains, and
planes are needed to move goods and people to the far-flung American
citizenry.
As a result of the nation’s high energy consumption, the United States
accounts for nearly 20 percent of the global emissions of greenhouse
gases. These gases—carbon dioxide, methane, and oxides of nitrogen—result
from the burning of fossil fuels, and they can have a harmful effect on
the environment. C Service and Commerce Sector
By far the largest sector of the economy in terms of output and
employment is the service and commerce sector. This sector grew rapidly
during the last part of the 20th century, creating many new jobs and more
than offsetting the slight loss of jobs in manufacturing industries. In
1998 commerce and service industries generated 72 percent of the GDP and
employed 75 percent of the U.S. workforce. Most of these jobs are
classified as white collar, and many require advanced education. They
include many high-paying jobs in financing, banking, education, and
health services, as well as lower-paying positions that require little
educational background, such as retail store clerks, janitors, and fast-
food restaurant workers.
C1 Service Industries The service sector is extremely diverse.
It includes an assortment of private businesses and government agencies
that provide a wide spectrum of services to the U.S. public. Services
industries can be very different from each other, ranging from health-
care providers to vacation resorts to automobile repair shops. Although
it would be almost impossible to list every kind of service industry
operating in the United States, many of these businesses fall into one of
several large service categories.
C1a Banking and Financial Services
In 1995 the U.S. financial market had a total of 628,500 institutions,
which employed 7.0 million people. These institutions included
investment, commercial, and savings banks; credit unions; mortgage banks;
insurance companies; mutual funds; real estate agencies; and various
holdings and trusts.
Banks play a central role in any economy since they act as intermediaries
in the flow of money. They collect deposits and distribute them as loans,
allowing depositors to save for future consumption and allowing borrowers
to invest. In 1998 the United States had 10,481 insured banks and savings
institutions with a total of 84,123 banking offices. Because of mergers
and closures, the number of banks steadily declined in the 1980s and
1990s while the number of bank offices increased. Combined assets of
insured banks and savings institutions totaled $5.44 trillion in 1998.
Banking in the 1990s was a highly competitive business, as banks offered
a variety of services to attract customers and sought to stem the flow of
investors to brokerage houses and insurance firms. Large banks in the
United States, in terms of assets, include Chase Manhattan Corporation,
Citibank, Morgan Guaranty Trust, and Bankers Trust, all headquartered in
New York City; Bank of America, headquartered in San Francisco; and
NationsBank, headquartered in Charlotte, North Carolina.
In 1998 the United States had 1,687 savings and loan associations (SLAs),
with combined assets of $1.1 trillion. SLAs are similar to banks, in that
they accept deposits from customers, but SLAs focus primarily on the
housing and building industries by making loans to home buyers. The
industry was substantially restructured in the late 1980s and early 1990s
after some prominent SLAs became insolvent largely because of falling
real estate prices in some parts of the country.
In addition, a host of other professions offer financial services to
individuals and corporations. Insurance companies provide insurance as
well as a variety of other services, including deposit accounts, pension
management, mutual funds, and other investments. Stockbrokers, investment
experts, pension managers, and personal financial consultants advise
consumers on investing money. In addition, corporate finance managers,
accountants, and tax consultants make recommendations on financial
planning to businesses and individuals.
C1b Travel and Tourism
One of the largest service industries in the United States is travel and
tourism. In 1997, individual U.S. citizens took 1.3 billion trips within
the United States to destinations that were at least 100 miles
(equivalent to 160 km) from home. In increasing numbers, domestic and
foreign travelers are visiting theme parks, natural wonders, and points
of interest in major cities, and the convention business is booming. New
York City is a popular destination, and tourism is a mainstay of the
economies of California, Florida, and Hawaii.
In recent decades, visitors from overseas have become an increasingly
important part of the U.S. tourism business. In 1970 about 2.3 million
overseas visitors came to the United States, spending $889 million. By
1997 the number of overseas visitors—chiefly from western Europe, Japan,
Latin America, and the Caribbean—was 48 million. Millions of visitors
from Canada and Mexico also cross the border every year. Estimated annual
expenditures in the United States by Canadian travelers totaled $6
billion, and spending by Mexicans was $5 billion.
America’s historic sites and national parks draw many visitors. In 1998,
287 million visits were made to the more than 350 areas administered by
the National Park Service. Millions of people each year visit the
national monuments, buildings, and museums in the Washington, D.C., area.
More than 14 million visits are made annually to Golden Gate National
Recreation Area in the San Francisco region. More than 19 million people
per year travel on the Blue Ridge Parkway in North Carolina and Virginia,
and about 6 million visit the Natchez Trace Parkway in Mississippi,
Alabama, and Tennessee. Located within a day’s drive from most parts of
the eastern United States, Great Smoky Mountains National Park is the
most popular national park in the United States, receiving nearly 10
million visitors annually.
C1c Transportation
Transportation-related businesses are an important part of the service
industry. Trucks, railroads, and ships transport goods to markets across
the country. Commercial airlines, railroads, bus companies, and taxis
move tourists and commuters to their destinations. The U.S. Postal
Service and a number of private carriers deliver goods as well as mail to
consumers. The U.S. transportation network spreads into all sections of
the country, but the web of railroads and highways is much denser in the
eastern half of the United States, where it serves the nation’s largest
urban, industrial, and population concentrations.
As of 1996 the 10 largest railroad companies in the United States
operated 72 percent of tracks. Takeovers and mergers among the major
private railroad companies were common during the 1980s and 1990s. Amtrak
(the National Railroad Passenger Corporation), a federally subsidized
organization, operates almost all the intercity passenger trains in the
United States. It carried 20.2 million passengers in 1997. Although rail
passenger travel has declined in importance during the 20th century, some
U.S. cities still maintain extensive subways or commuter railways,
including New York City, Washington, D.C., Chicago, and the San Francisco-
Oakland area of California.
During the early decades of the 20th century, motor vehicle transport
developed as a serious competitor of the railroads, both for passengers
and freight. Federal aid to states for highway construction began with
the passage of the Federal-Aid Road Act of 1916.
The federal aid program was greatly expanded in 1956 when the government
began an ambitious expansion of the Interstate Highway System, a 74,165-
km (46,084-mi) network of limited-access highways that connects the
nation’s principal cities. This carefully designed system enables
motorists to drive across the country without encountering an
intersection or traffic signal. It carries about 20 percent of U.S. motor-
vehicle traffic, though it accounts for just over 1 percent of U.S. roads
and streets. The system is designed for safe, efficient driving, with
gentle curves, easy grades and long sight distances. Entering and exiting
the highway system is permitted only at planned interchanges.
Air transport began to compete with other modes of transport in the
United States after World War I (1914-1918). The first commercial flights
in the United States were made in 1918 and carried small amounts of mail.
Passenger service began to gain importance in the late 1920s, but air
transport did not become a leading mode of travel until the advent of
commercial jet craft after World War II. By the 1990s a growing number of
Americans flew for personal and business travel, in part because of the
need to cover long distances and in part because they like to get to
their destinations quickly. In 1997 airlines in the United States carried
598.1 million passengers, the vast majority of whom were domestic
travelers.
By the end of the 20th century, large and small airports across the
nation formed a network providing air transportation to individual
travelers. The nation had 5,129 public and 13,263 private airports in
1996. The largest airports in the United States by passenger arrivals and
departures are William B. Hartsfield International Airport near Atlanta,
Georgia; Chicago-O’Hare International Airport in Illinois; Dallas-Fort
Worth Airport in Texas; and Los Angeles International Airport in
California.
The United States has a relatively small commercial shipping fleet. In
1998 only 473 vessels of 1,000 gross tons and larger were registered in
the United States. Only 56 percent were in use; most of the remainder
formed part of a government-owned military reserve fleet. However, many
American ship owners register their vessels in foreign countries such as
Liberia and Panama, where crew wages, taxes, and operating costs are
lower.
In terms of the number of ships docking, New Orleans, Louisiana, is the
busiest port in the nation; each year it handles more than 6,000 vessels.
Other leading ports include Los Angeles-Long Beach, California; Houston,
Texas; New York, New York; San Francisco-Oakland, California; Miami,
Florida; and Philadelphia, Pennsylvania. Crude petroleum accounts for 22
percent of the waterborne tonnage of the United States. Petroleum
products make up 18 percent. Coal accounts for 14 percent, and farm
products for 14 percent.
The inland waterway network of the United States has three main
components—the Mississippi River system, the Great Lakes, and the coastal
waterways. Some 66 percent of the annual water freight traffic is on the
Mississippi River and its tributaries, 17 percent is on the Great Lakes,
and most of the remainder is on the coastal waterways. A major
thoroughfare of the coastal waterways is the Intracoastal Waterway, a
navigable, toll-free shipping route extending for about 1,740 km (about
1,080 mi) along the Atlantic Coast and for about 1,770 km (about 1,100
mi) along the Gulf of Mexico coast. About 45 percent of the total annual
traffic on all coastal waterways travels on the Gulf Intracoastal
Waterway, about 30 percent is on the Atlantic Intracoastal Waterway, and
about 25 percent is on Pacific Coast waterways.
Most goods in the United States travel by railroad and truck, which
compete vigorously for freight transport. In 1996, 38 percent of all
United States freight moved by rail and about 27 percent traveled by
truck. However, other modes of transportation more easily handle special
freight items. An additional 20 percent of all freight, by volume, moved
through pipelines, mainly oil and natural gas pipelines originating in
Texas and Louisiana with destinations in the Midwest and Northeast.
Another 16 percent, mainly bulk commodities like coal, grain, and
industrial limestone, moved by barge on inland waters.
C1d Government
Federal, state, and local governments provide a sizeable portion of
services delivered in the nation. In 1996, government workers made up 4
percent of all workers and together produced 12 percent of GDP.
Government services include items as such Social Security benefits,
national defense, education, public welfare programs, law enforcement,
and the maintenance of transportation systems, libraries, hospitals, and
public parks.
The government sector in the U.S. economy has increased dramatically in
size during the 20th century. Federal revenues grew from less than 5
percent of total GDP in the early 1930s to more than 20 percent by the
late 1990s. Much of this growth took place during two time periods. In
the 1930s, following the economic downturn of the Great Depression, U.S.
president Franklin D. Roosevelt instituted sweeping social programs
designed to provide basic financial security to individuals and families.
Many of these programs, such as unemployment insurance and Social
Security payments to retirees, have remained in place since then. During
the 1960s, U.S. president Lyndon B. Johnson instituted a series of
programs designed to fight poverty, promote education, and provide basic
medical coverage for less-affluent Americans. In addition, during the
last half of the 20th century, government expenditures increased for
medical care and national defense as a result of technological advances.
The cost of transportation construction also rose as the growing
population demanded more and better highway systems.
C1e Entertainment
Another leading industry is the entertainment business. Motion picture
production has been centered in Hollywood, California, since the early
decades of the 20th century, when the budding motion picture industry
discovered that the warm climate and sunny skies of southern California
provided ideal conditions for film production. Other entertainment
industries include theater, which tends to be located in larger urban
areas, particularly New York City, and television, with major networks
operating out of the New York City area. .
C2 Commerce The 1990s have been years of unrivaled prosperity
in the United States, with per capita GDP reaching $30,450 by 1998. This
high quality of life results partly from a rapid expansion of commerce in
the years following World War II.
C2a Domestic Trade
Convenience is the key to consumer markets in the United States, whether
it is fast food, movie theaters, clothing, or any of hundreds of
different types of consumer goods. Products are being delivered to
citizens in a more efficient manner, as industries and business firms
have decentralized to more closely fit the distribution of population.
Malls have sprung up in suburban areas, making the downtown department
store obsolete in many smaller cities. Manufacturers also market their
goods directly to customers in factory outlet malls. Prices are often
lower in these outlets than in regular retail stores. Customers often
travel hundreds of miles to shop at larger factory outlet malls. At the
other end of the spectrum, mail order catalogs and Internet sites have
made it possible for many consumers to purchase products directly from
companies by mail or using personal computers.
Wholesalers and retailers carry on most domestic commerce, or trade, in
the United States. Wholesalers buy goods from producers and sell them
mainly to retail business firms. Retailers sell goods to the final
consumer. Wholesale and retail trade together account for 16 percent of
annual GDP of the United States and employ 21 percent of the labor force.
Wholesale establishments conducted aggregate annual sales of $3.2
trillion in 1992. The leading type of wholesale business is the
distribution of groceries and related products, which accounts for 16
percent of all wholesale activity. Next in rank are motor-vehicle parts
and supplies; petroleum and petroleum products; professional and
commercial equipment, and machinery, equipment, and supplies. Wholesalers
tend to be located in large urban centers that enable them to distribute
goods over wide sections of the nation. The New York City metropolitan
area is the country’s leading wholesale center. It serves as the national
distribution center for a variety of goods and as the main regional
center for the eastern United States. Other leading wholesale centers
include Los Angeles, the main center for the western part of the United
States; Chicago; San Francisco; Philadelphia; Houston; Dallas; and
Atlanta.
In the mid-1990s retail establishments in the United States had aggregate
annual sales of $2.2 trillion. Automotive dealers, with 23 percent of the
total yearly retail trade, and food stores, with 18 percent, are the
leading retailers. The volume of retail sales is directly related to the
number of consumers in an area. The four leading states in annual retail
sales—California, Texas, Florida, and New York—are also the four most
populous states.
C2b Foreign Trade
The United States is the world’s leading trading nation, with total
merchandise exports amounting to $683 billion, and imports to $944.6
billion. Despite its massive size, large population, and economic
prosperity, the United States economy can provide a higher quality of
life for consumers and more opportunity for businesses by trading with
other nations. Foreign, or international, trade enables the United States
to specialize in producing those goods that it is best suited to make
given its available resources. It then imports products that other
nations can make more efficiently, lowering prices of these goods for
U.S. consumers.
Nonagricultural products usually account for 90 percent of the yearly
value of exports, and agricultural products account for about 10 percent.
Machinery and transportation equipment make up the leading categories of
exports, amounting together to one-third of the value of all exports.
Other leading exports include electrical equipment, chemicals, precision
instruments, and food products. Beginning in the mid-1970s, the nation’s
imports of petroleum from the Middle East and manufactured goods from
Canada and Asia (especially Japan) created a trade imbalance.
D Information and Technology Sector
By the end of the 20th century, many technological innovations had been
introduced in the United States. Communications satellites orbited the
earth, computers performed day-to-day functions in many businesses, and
the Internet provided instant information on most aspects of U.S. life
via computer. Developments in communications and technology have
transformed many aspects of daily life in the United States, from
improvements in kitchen appliances to advances in medical treatment to
television broadcasts that are transmitted live via satellite from around
the world.
An increasing number of job opportunities are opening in fields related
to the research and application of new technology. Entirely new
industries have emerged, such as companies that build the equipment used
in space explorations. In addition, technology has opened new
opportunities for investment and employment in established industries,
such as those that manufacture medicines and machines used in the
detection and treatment of diseases and individuals who market and sell
products via the Internet.
D1 Communications
The communications systems in the United States are among the most
developed in the world. Television, radio, newspapers, and other
publications, provide most of the country’s news and entertainment. On
average there are two radios and one television set for every person in
the United States. Although the economic output of the communications
industry is relatively small, the industry has enormous importance to the
political, social, and intellectual activity of the nation. Most
communication media in the United States are privately owned and operate
independently of government control.
The Federal Communications Commission must license all radio and
television broadcasting stations in the United States. In 1997, 1,285
television broadcasters were in operation. All states had television
stations, and more than 40 percent of the stations were concentrated in
nine states: Texas, California, Florida, New York, Pennsylvania, Ohio,
Illinois, Michigan, and North Carolina. A rapidly growing number of U.S.
households (estimated at 64 million in 1997) subscribed to cable
television. An estimated 98.3 percent of U.S. households had at least one
television set. Telephone communication changed as cellular phones
allowed people to communicate via telephone while away from their homes
and businesses or while traveling. There were 69 million cellular phones
in use in 1998.
There were 1,489 daily newspapers published in the United States in 1998,
8 fewer than the year before. Daily newspapers had a circulation of
approximately 60.1 million copies in 1998. The top daily newspapers in
the United States according to circulation were the Wall Street Journal
(published in New York City), USA Today (published in Arlington,
Virginia), the New York Times, and the Los Angeles Times, each with a
circulation in excess of 1 million. Other leading newspapers included the
Washington Post, the New York Daily News, the Chicago Tribune, the
Detroit Free Press, the San Francisco Chronicle, the Chicago Sun-Times,
the Dallas Morning News, the Boston Globe, and the Philadelphia Inquirer.
Nearly 21,300 periodicals were published in 1997. These ranged from
specialized journals reaching only a small number of professionals to
major newsmagazines such as Time, with a circulation of 4.1 million a
week, and Newsweek, with a circulation of 3.2 million a week. Other mass
publications with vast audiences included the weekly TV Guide, reaching
13.2 million readers, and the monthly Reader’s Digest, with a circulation
of 15.1 million copies.
D2 Technology
One of the most far-reaching technological advances of the late 20th
century took place in the field of computer science. Computers developed
from large, cumbersome, and expensive machines to relatively small and
affordable devices. The development of the personal computer (PC) in the
1970s made it possible for many individuals to own computers and allowed
even small businesses to use computer technology in their operations. The
U.S. Bureau of the Census estimates that jobs in the computer industry
are growing at the fastest rate of any employment area, with job openings
for computer specialists expected to double from 1996 to 2006.
The Internet began in the 1960s as a small network of academic and
government computers primarily involved in research for the U.S.
military. Originally limited to researchers at a handful of universities
and government facilities, the Internet quickly became a worldwide
network providing users with information on a range of subjects and
allowing them to purchase goods directly from companies via computer. By
1999, 84 million U.S. citizens had access to the Internet at home or
work. More and more Americans were paying bills, shopping, ordering
airline tickets, and purchasing stocks via computer over the Internet.
