Note: When a legislature determines that government involvement is needed in a particular social activity or problem, it may write legislation creating an agency either directly or by authorizing the executive to set it up. Agencies exist at the federal, state, and local levels. Most federal agencies are attached to the executive branch of government. Some agencies (such as the Environmental Protection Agency) are called an agency. An agency may, however, be called such other names as board (as the National Labor Relations Board), commission (as the Securities and Exchange Commission), administration (as the Social Security Administration), and service (as the Internal Revenue Service). Agencies at the federal level are governed by the provisions of the Administrative Procedure Act, which is found at title 5 of the U.S. Code.
