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. Here we will provide you with an overview of the CityScore tool and data, but more importantly we will show you how we are using CityScore to make improvements across the City.

The Score

  • <

    Scores below 1 indicate that performance is below the target.

  • 1.0
  • >

    Scores above 1 indicate that performance is exceeding the target.

  • Today's Score -

Please note: daily scores reflect activity from the previous weekday, weekly scores reflect activity from the previous 7 days, monthly scores reflect activity from the previous month (on a rolling basis), and quarterly scores reflect activity from the previous quarter (on a rolling basis).

Improving EMS response time

If you report a life-threatening injury or illness via 911 it triggers a priority 1 response from Boston Emergency Medical Services (Boston EMS). Our goal is for an ambulance to arrive on scene in 6 minutes or less because the quicker someone in a life-threatening situation receives medical care, the better their chance of survival.

When CityScore launched January 15th, EMS median priority 1 response times for the previous month averaged 5 minutes 59 seconds, which grew to 6 minutes 11 seconds by April 2015, causing its CityScore to drop below 1. Concerned by increasing response times, Mayor Walsh reached out to the Chief of EMS to get more information on what was going on and what the City could do to reverse the trend.

We found that increases in visitors and the City's resident population over the past several years led to a rise in emergency medical 911 calls, yet EMS’ budget had not grown to allow them to hire more EMTs and replace aging ambulances. Hearing this, the Mayor prioritized funding in the next City budget for EMS to train a new class of 20 EMTs and buy 10 replacement ambulances. The added personnel will allow for two additional ambulances to serve Boston's neighborhoods. We hope these new resources will help EMS shorten response times for the most serious emergencies and provide world-class emergency medical services to the residents of Boston.

Installing traffic signs

The Boston Transportation Department installs and maintains signs across the City - anything from street signs to stop signs. These signs help drivers, cyclists and pedestrians move safely on Boston’s streets.

While testing CityScore in late 2015 up through the public launch, we noticed the on-time percentage for sign installation from December 1st 2015 through January 14th 2016 was 73% (7% below target). We looked into why this was happening and discovered a backlog of 90 sign installation requests. Being able to see the data every day in CityScore allowed us to identify this issue faster than with traditional reporting, and within 7 days the request backlog was reduced from 90 to 7. And since CityScore launched on January 15th, over 88% of sign installation cases have been closed on time.

Sign installation CityScore increased 21% in just 6 months!

What We’re Working On Now

CityScore has also highlighted potential areas for improvement in constituent engagement and basic city services. We’re currently working to:

  • Increase the capacity of our 311 call center to ensure your calls are answered faster
  • Improve streetlight maintenance processes to keep streets well-lit and safe
  • Evaluate the impact of new EMS resources on response times

We will be updating this site periodically with the results of this work. Please come back to see the progress we are making!
