communities — gates for crime and traffic. Purpose-designed communities — catering to foreigners (e.g. worker compounds in Mid-West Asia, built largely for the oil industry) Comparison to closed cities The closed cities of Russia are different from the gated communities. The guard duty in closed cities is free to residents (paid by taxes). The public transport in closed cities may go with transit checkpoints or checking passes/passports at technical stops and available to others outside the security area. Within a gated community in the best cases, the bus stop is opposite the checkpoint; a few offer free buses. Via gated communities buses go due to easement or good will. Fares and communal payment in closed cities are often equal (in all cases not greater) if it would be a common city. In gated communities service companies raise non legally fixed tariffs because it is difficult for those communities either to negotiate lower terms or knock out this service company (in most cases the result is no quorum). Countries A limited number of gated communities have long been established for foreigners in various countries of the world: The worker compounds in the Middle East, built largely for the oil industry. The Arbor Oaks subdivision located in El Monte, California, which appears in the film Back to the Future Part II as "Hilldale", is now gated because of the fans coming to see it in person. Residents are sometimes angry at fans who come by the development. Argentina There are many gated communities in Argentina, especially in Greater Buenos Aires, in the suburb of Pilar, 60 km N of Buenos Aires city, and in other suburban areas, such as Nordelta. Tortugas Country Club was the first gated community developed in Argentina, dating from the 1930s/1940s, but most date from the 1990s, when liberal reforms were consolidated. Since Buenos Aires has been traditionally regarded as a socially integrated city, gated communities have been the subject of research by sociologists. Gated communities are an important way through middle and upper-class people cope with the high levels of violent criminal activity in Greater Buenos Aires. Australia Although gated communities have been rare in Australia, since the 1980s, a few have been built. The most well-known are those at Hope Island, in particular Sanctuary Cove, on the Gold Coast of Queensland. Other similar projects are being built in the area. In Victoria, the first such development
