CompStat—or COMPSTAT, short for Computer Statistics—is a computerization and quantification program used by police departments. It was originally set up by the New York City Police Department in the 1990s. Variations of the program have since been used in police departments across the world.[1] According to a 2022 podcast by Peter Moskos with John Yohe and Billy Gorta, the name CompStat was suggested by detective Richard Mahere for the computer file name of the original program to comply with 8.3 filename conventions, short for "Comparative Statistics" and "Computer Statistics.".[2]

Origins

COMPSTAT is a management system created in April 1994 by Bill Bratton and Jack Maple, who Bratton met while serving as chief of the New York City Transit Police and hired him as the New York Police Department's top anti-crime specialist when he became Police Commissioner in 1993.[3]

COMPSTAT began as weekly meetings at One Police Plaza where officers were randomly selected from precincts and quizzed about crime trends in their districts and how to respond.[3] At the time, the NYPD collected crime statistics every 6 months; under threat of transfers, they began to collect information daily.[3] In February 1994, the department heads provided a hand count of major crimes in the first 6 weeks of 1993 and 1994.[4]

Maple drafted junior staffer John Yohe to modify an existing program to analyze the data.[3] COMPSTAT was named after a program called "compare stats".[4] It was originally ran on Informix's SmartWare desktop office system before being replaced by Microsoft's FoxPro database for business.[4] The Patrol Beureau's staff computerized the information provided by department heads and created the first 'CompStat' book, collating the information by precinct, patrol borough, and city.[4]

Impact

Crime rates decreased while CompStat was implemented, leading to widespread public praise of the program.[5] Research is mixed on whether CompStat played a role.[5][4] Proponents of CompStat have argued that the program was responsible was the decrease, others have noted decreases in other cities with different policing models during the same period.[4][3] A 2021 study found no evidence that CompStat had an impact on serious crime, but the study did find substantial evidence that the program led police to engage in substantial data manipulation.[6]

An anonymous survey of retired high-ranking police officials found that pressure to reduce crime prompted some supervisors and precinct commanders to distort crime statistics.[7] In 2010 NYPD officer Adrian Schoolcraft released recordings of his superiors urging him to manipulate data.[8][9][10] In 2014 Justice Quarterly published an article stating that there was statistical evidence of the NYPD manipulating CompStat data.[11]

NYPD Captains Endowment Association

On June 24, 2020, the NYPD Captains Endowment Association president, Chris Monahan, wrote a letter to then NYC Mayor Bill de Blasio and Police Commissioner Dermot Shea calling for the NYPD to end its use of COMPSTAT. His criticisms of COMPSTAT include dividing police and the community, particularly black and brown communities, and increasing the chances of officers engaging in street encounters. [12]

When Compstat was developed under then Police Commissioner Bill Bratton, high-ranking police officials widely incorporated the "stop, question and frisk".[13] Statistically, no relationship between stop-and-frisk and crime seems apparent. A 2016 Brennan Center analysis showed part of New York remaining safer was the introduction of CompStat.[14]

TrafficStat

The NYPD's TrafficStat was modeled after CompStat. TrafficStat tracks motor vehicle, bicyclist, and pedestrian crashes.[15]

  • In the CBS TV series The District, inspired by the real-life experience of former New York Deputy Police Commissioner Jack Maple, statistics clerk Ella Mae Farmer (played by Lynne Thigpen)[16] was shown to be a wiz at using the system, which proved invaluable to the success of Washington, D.C. Police Chief Jack Mannion and to the department, and which contributed to her promotion from an obscure position located in an out-of-the-way office to Director of Administrative Services.[17]
  • The system is shown in use in Baltimore, Maryland, in The Wire on HBO, though in the show it is referred to as "ComStat". (Baltimore's real-life system is called Citistat.)[18]
  • The podcast Reply All aired two episodes regarding CompStat, titled "The Crime Machine Part I"[19] and "The Crime Machine Part II".[20]
