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 of cities of 2,000 to 4,999 population, and 42 percent for cities of less than 2,000 population. The tables provide a profile of all sworn, civilian, full-time, and part-time personnel serving the responding police departments. The data shows personnel strength, departmental positions, age, experience, and education. The statistics also show staff turnover and educational benefits. Data are arranged by municipality, in descending order by population. For related volumes giving other statistics on Iowa's police, see NCJ-88880 and 88882-83.
