Security guards and gaming surveillance officers held over 1.0 million jobs in 2004. Over half of all jobs for security guards were in investigation and security services, including guard and armored car services. These organizations provide security on a contract basis, assigning their guards to buildings and other sites as needed. Most other security officers were employed directly by educational services, hospitals, food services and drinking places, traveler accommodation (hotels), department stores, manufacturing firms, lessors of real estate (residential and nonresidential buildings), and governments. Guard jobs are found throughout the country, most commonly in metropolitan areas. Gaming surveillance officers worked primarily in gambling industries; traveler accommodation, which includes casino hotels; and local government. Gaming surveillance officers were employed only in those States and on those Indian reservations where gambling has been legalized.
A significant number of law enforcement officers work as security guards when they are off duty, in order to supplement their incomes. Often working in uniform and with the official cars assigned to them, they add a high-profile security presence to the establishment with which they have contracted. At construction sites and apartment complexes, for example, their presence often deters crime. (Police and detectives are discussed elsewhere in the Handbook.)
