CityScore is an initiative designed to inform the Mayor and city managers about the overall health of the City at a moment’s notice by aggregating key performance metrics into one number. They provide an overview of the CityScore tool and data, but more importantly they show the potential users how they are using CityScore to make improvements across the City. Among others the CityScore measures 311 call center performance, Boston Fire Incident, Boston Public Schools Attendance, Code enforcement on-time, Graffiti removal, Homocides, Library users, Park maintenance, Shootings, Streetlight outages and Tree maintenance on-time.
