“Pork barrel is the appropriation of government spending for localized projects secured solely or primarily to bring money to a representative’s district. The usage originated in American English. In election campaigns, the term is used in derogatory fashion to attack opponents. However, scholars use it as a technical term regarding legislative control of local appropriations.
Typically, “”pork”” involves funding for government programs whose economic or service benefits are concentrated in a particular area but whose costs are spread among all taxpayers. Public works projects, certain national defense spending projects, and agricultural subsidies are the most commonly cited examples.”
