Abstract: This survey, the first in the Bureau of Justice Statistics' new program on Law Enforcement Management and Administrative Statistics (LEMAS), presents information on three types of general purpose law enforcement agencies: state police, local police, and sheriffs' departments. Data from the primary state police agency in each of 49 states (Hawaii does not have a state police agency) are also presented. Variables include size of the populations served by the typical police or sheriffs' department, levels of employment and spending, various functions of the department, average salary levels for uniformed officers, and other matters relating to management and personnel.

UNIVERSE: All United States state law enforcement agencies and city and township law enforcement agencies.

SAMPLE: State law enforcement agencies and city and township law enforcement agencies with 135 or more sworn employees were selected. County police, as distinguished from sheriffs' departments, were combined with municipal and township law enforcement agencies in the category of local police agencies. The remaining agencies were selected in a two-stage process. The first stage units were counties, the same as those selected for the SURVEY OF INMATES OF LOCAL JAILS, 1983 [UNITED STATES] (ICPSR 8274). For that survey, all counties in the United States were divided into five strata based on the average daily inmate population of the jails in the county. The first stratum included all counties containing jails with average daily populations of 100 inmates or more. These counties were included with certainty. The other four strata, with decreasing average jail populations, were sampled at varying intervals. A sixth stratum was added for the LEMAS survey to represent those states with combined jail/prison systems that were not included in the 1983 Survey of Local Jails. All counties in these states were included with certainty. All county-level law enforcement agencies in the counties selected for the sample were included in the survey. The second stage units were municipal and township law enforcement agencies. A sample of these agencies was selected from within the six strata based on the number of sworn employees in the agency. In all, 3,054 law enforcement agencies were included in the sample. The final weight assigned to each case was the inverse of its probability of selection.

NOTE: The LEMAS survey will be repeated in 1990 and every 3 years thereafter. The number of sheriffs' agencies in this report may not correspond exactly to the totals found in other publications. Also, the total number of agencies is the result of the weighted sample and not an exact count of all agencies nationwide. During the course of data collection, the sampling frame was found to be deficient in Texas because a number of constable offices had not been included. A systematic sample of one-fourth of these offices was added to the survey.
