While the police force is nationally controlled and funded, each district in Lima has a community policing structure called Serenazgo. The quantity of Serenazgos officials and resources varies by district. For example, Villa Maria del Triunfo has 5,785 citizens per official. Twenty-two districts in Lima have a ratio above 1000 citizens per Serenazgo official, while 14 districts have ratios below 200 citizens per official, including Miraflores with 119 and San Isidro with 57.
