The department personnel includes over 1450 full-time sworn members. The department responds to more than 950,000 police calls per year on average. The most recent census ranked Nashville as the 21st largest U.S. city. In 2000 the
Department of Justice ranked the Metropolitan Nashville Police Department as the 36th largest U.S. police department. The department is configured in a decentralized format, providing its precinct commanders with control of their own resources to address issues and crime trends in their areas. The department is divided into eight precincts: North, South, East, West, Central, Hermitage, Madison, and Midtown Hills. A
precinct is designed similarly to a medium-sized police department, with uniform patrol, undercover officers, directed patrol officers, plainclothes detectives, and other specialties. In February 2019, a new headquarters was opened at 600 Murfreesboro Pike. This replaced the old headquarters, which was located at 200 James Robertson Parkway. The precincts are supported by Administrative Services, Investigative Services, and Special Operations Division personnel, all in an effort to deter, detect, prevent, and respond to criminal trends in the precinct areas. The department's entire focus is on how to quickly identify trends and implement initiatives that address them. ==Rank structure==
