Project Overview

The New Haven Police Department (NHPD), working with the University of New Haven, implemented the Policing from Analysis to Solutions program to institutionalize the use of evidence-based problem-solving practices throughout the police department, using geospatial predictive analysis and threshold analysis to inform the focus of police and community resources. This project sought to prioritize the use of police and community resources by identifying abnormal or persistent patterns in crime type by location and directing focused problem-solving methods to the specific problems of each community policing district in New Haven. The result was a decrease in violent crime and better use of department resources.
