What is the largest police force in the world?

The World's Largest Municipal Police Force

When thinking of massive law enforcement organizations, national agencies like India's state police forces or China's People's Armed Police usually top global rankings by pure headcount. However, when it comes to local urban law enforcement, the New York City Police Department (NYPD) stands out as the largest municipal police force in the world.

Founded in 1845, the NYPD oversees public safety across New York City's five boroughs. To manage a complex population of over 8 million residents—plus millions of daily commuters and tourists—the department employs approximately 33,000 sworn officers alongside roughly 19,000 civilian personnel. Its vast operations span 78 patrol precincts, dedicated subway transit districts, and specialized units ranging from counterterrorism to emergency services.

Running an operation of this magnitude requires a budget that rivals the defense spending of small nations. Beyond standard precinct patrols, the NYPD operates high-tech intelligence centers and deploys specialized response units equipped to handle everything from harbor patrol to complex cybercrime investigations. While nationwide state police forces employ more total personnel across vast territories, no single city maintains a local police organization quite as large or resource-intensive as New York's iconic force.
