The fairground industry is important economically for leisure and tourism and, in the case of older traditional rides, for the preservation of national heritage. A trip to the fair or amusement park is an increasingly popular leisure activity. Different types of fairgrounds exist: a) amusement and theme parks - fixed sites where rides are permanently or semi-permanently installed, and b) traveling fairs - temporary sites, often occupied for the same slot each year, where traveling showmen set up and operate mobile rides.
The operation of concessions, rides, and vendors at fairgrounds are subject to local and state regulation under the police powers to protect the health and welfare of the population. Definitions vary from state to state, however, a fairgrounds "concession" may mean any show, amusement other than an amusement ride, game, or novelty stand operation at a fair or exposition, but may not include food or drink operations. Licensing of certain fairgrounds operations is often required, such as amusement rides and gaming exhibitors. Amusement rides are subject to manufacturing standards and periodic inspections. Statutory authority regulates liquor sales and consumption at fairgrounds, as well as fireworks exhibits. Often, there will be security or police officers required on the site to enforce compliance will the applicable laws.
