Police agencies provided data in response to a 1981 survey questionnaire (distributed jointly by the Police Executive Research Forum and the Police Foundation) sent to more than 150 police agencies serving populations of 50,000 or more. Summary data are broken down by jurisdictions' population size and, in many cases, by geographic region; each survey question lists all responses from individual agencies. Tables present the range and median per-capita costs of policing, number of officers per 1,000 population, salary ranges by officer type, sick leave and vacation benefits, retirement eligibility, and the degree of centralization of investigative personnel. Other tables list manpower allocations by shift, percentages of motor and foot beats by shift, percentages of civilian officers and minority employees, and numbers of policewomen by rank. Data are also given on promotion procedures, use of computers, number of citizen calls, and number of firearms incidents and injuries. Further tables provide information on court time compensation, disability benefits, longevity pay, personnel shortages, residency requirements, review boards, uniform allowances, and vehicles. An appendix lists participating police agencies by population and geographic location.
