Final answer:
Only about 6% of all municipal police departments in the U.S. employ more than 100 full-time officers, generally found in major metropolitan areas.
Step-by-step explanation:
The percentage of municipal police departments that employ more than 100 full-time officers is relatively small. Most police departments in the United States are made up of a smaller number of officers, often due to the population size and budget constraints of the municipalities they serve.
According to the Bureau of Justice Statistics, only about 6% of all municipal police departments in the United States have more than 100 full-time sworn officers. These larger departments are typically found in major metropolitan areas, where the demand for law enforcement resources is higher due to larger populations and higher crime rates.
