Information and data are presented on the growth of the security industry, the percentage market share of 1993 expenditure for various components of the security industry, operating costs, in-house security, reorganizations in proprietary security staff, employment, and security equipment sales. Overall, this study concludes that total private security employment will continue to increase over the decade; however, in 1993 proprietary security (security personnel directly hired by a business proprietor) will employ 22,000 fewer people than in 1990. Still, proprietary security employment constitutes one- third of all persons employed in the security industry. The private-security sector of the national economy continues to be one of the fastest growing sectors, as the industry ranks in the top 10 among service industries. Security-industry problems that persist are inadequate pre-employment screening and entry-level security training, a paucity of security standards, personnel turnover, questionable benefits from government regulation of security businesses, and false alarms. 5 exhibits
