The statistics show the caliber of weapons authorized, types of equipment owned by each department, numbers of vehicles used, and replacement schedules for equipment and vehicles. Tables also show the number of trips for service and investigations, number of sworn and unsworn personnel by staff function, crime prevention programs, and daily cost per prisoner for contracted jail services. Data came from a survey initially distributed in March 1981 to all agencies with full-time, paid police officers. The response rate was 100 percent for cities with 5,000 population or more, 73 percent for cities with 2,000, to 4,999 population, and 42 percent for cities of less than 2,000. Data are arranged by municipality, in descending order by population. For related volumes giving additional statistics on Iowa's police, see NCJ 88880-2.
