The nature and purpose of these agencies vary widely. Some are regulatory groups with powers to supervise certain sectors of the economy. Others provide special services either to the government or to the people. In most cases, the agencies have been created by Congress to deal with matters that have become too complex for the scope of ordinary legislation. In 1970, for example, Congress established the Environmental Protection Agency to coordinate governmental action to protect the environment. Among the most important independent agencies are the following:
The Central Intelligence Agency (CIA) coordinates the intelligence activities of certain government departments and agencies; collects, correlates, and evaluates intelligence information relating to national security; and makes recommendations to the National Security Council within the Office of the President.
The Environmental Protection Agency (EPA) works with state and local governments throughout the United States to control and abate pollution in the air and water and to deal with problems related to solid waste, pesticides, radiation, and toxic substances. EPA sets and enforces standards for air and water quality, evaluates the impact of pesticides and chemical substances, and manages the "Superfund" program for cleaning toxic waste sites.
The Federal Communications Commission (FCC) is charged with regulating interstate and international communications by radio, television, wire, satellite, and cable. It licenses radio and television broadcast stations, assigns radio frequencies, and enforces regulations designed to ensure that cable rates are reasonable. The FCC regulates common carriers, such as telephone and telegraph companies, as well as wireless telecommunications service providers.
The Federal Reserve Board is the governing body of the Federal Reserve System, the central bank of the United States. It conducts the nation's monetary policy by influencing the volume of credit and money in circulation. The Federal Reserve regulates private banking institutions, works to contain systemic risk in financial markets, and provides certain financial services to the U.S. government, the public, and financial institutions.
The Federal Trade Commission (FTC) enforces federal antitrust and consumer protection laws by investigating complaints against individual companies initiated by consumers, businesses, congressional inquiries, or reports in the media. The commission seeks to ensure that the nation's markets function competitively by eliminating unfair or deceptive practices.
The General Services Administration (GSA) is responsible for the purchase, supply, operation, and maintenance of federal property, buildings, and equipment, and for the sale of surplus items. GSA also manages the federal motor vehicle fleet and oversees telecommuting centers and child care centers.
The National Aeronautics and Space Administration (NASA) was established in 1958 to run the U.S. space program. It placed the first American satellites and astronauts in orbit, and it launched the Apollo spacecraft that landed men on the moon in 1969. Today, NASA conducts research aboard earth-orbiting satellites and interplanetary probes, explores new concepts in advanced aerospace technology, and operates the U.S. fleet of manned space shuttle orbiters.
The National Archives and Records Administration (NARA) preserves the nation's history by overseeing the management of all federal records. The holdings of the National Archives include original textual materials, motion picture films, sound and video recordings, maps, still pictures, and computer data. The Declaration of Independence, the U.S. Constitution, and the Bill of Rights are preserved and displayed at the National Archives building in Washington, D.C.
The National Labor Relations Board (NLRB) administers the principal U.S. labor law, the National Labor Relations Act. The board is vested with the power to prevent or remedy unfair labor practices and to safeguard employees' rights to organize and determine through elections whether to have a union as their bargaining representative.
The National Science Foundation (NSF) supports basic research and education in science and engineering in the United States through grants, contracts, and other agreements awarded to universities, colleges, and nonprofit and small business institutions. The NSF encourages cooperation among universities, industry, and government, and it promotes international cooperation through science and engineering.
The Office of Personnel Management (OPM) is the federal government's human resources agency. It ensures that the nation's civil service remains free of political influence and that federal employees are selected and treated fairly and on the basis of merit. OPM supports agencies with personnel services and policy leadership, and it manages the federal retirement system and health insurance program.
The Peace Corps, founded in 1961, trains and places volunteers to serve in foreign countries for two years. Peace Corps volunteers, now working in some 80 nations, assist in agricultural-rural development, small business, health, natural resources conservation, and education.
The Securities and Exchange Commission (SEC) was established to protect investors who buy stocks and bonds. Federal laws require companies that plan to raise money by selling their own securities to file reports about their operations with the SEC, so that investors have access to all material information. The commission has powers to prevent or punish fraud in the sale of securities and is authorized to regulate stock exchanges.
The Small Business Administration (SBA) was created in 1953 to advise, assist, and protect the interests of small business concerns. The SBA guarantees loans to small businesses, aids victims of floods and other natural disasters, promotes the growth of minority-owned firms, and helps secure contracts for small businesses to supply goods and services to the federal government.
The Social Security Administration (SSA) manages the nation's social insurance program, consisting of retirement, disability, and survivors benefits. To qualify for these benefits, most American workers pay Social Security taxes on their earnings; future benefits are based on the employees' contributions.
The United States Agency for International Development (USAID) administers U.S. foreign economic and humanitarian assistance programs in the developing world, as well as in Central and Eastern Europe and the New Independent States of the former Soviet Union. The agency supports programs in four areas — population and health, broad-based economic growth, environment, and democracy.
The United States Postal Service is operated by an autonomous public corporation that replaced the Post Office Department in 1971. The Postal Service is responsible for the collection, transportation, and delivery of the mails, and for the operation of thousands of local post offices across the country. It also provides international mail service through the Universal Postal Union and other agreements with foreign countries. An independent Postal Rate Commission, also created in 1971, sets the rates for different classes of mail.
