The Bloomberg Philanthropies City Data Alliance empowers cities to harness data and artificial intelligence to services and improve residents' lives. Established in 2022, 65 cities across 12 countries in North, Central, and South America, as well as the Caribbean have participated to date.

The suite of supports provided to cities in the City Data Alliance helps mayors and their municipalities use data to inform decisions, tackle complex challenges, communicate results, and look ahead. 

“Through the City Data Alliance, more cities are now using data across city hall agencies to tackle their toughest challenges, from expanding affordable housing to improving public transportation," said Michael R. Bloomberg, founder of Bloomberg Philanthropies and Bloomberg L.P. and 108th mayor of New York City. 

Already, cities’ work as part of the Bloomberg Philanthropies City Data Alliance has resulted in:

• New standards and staff upskilling in collecting and disaggregating data in Jackson, Mississippi is enabling the city to address root causes of crime and homelessness. This has helped the city create targeted programs to reduce youth violence and reach functional zero homelessness.
• The formation of a new dashboard in Recife, Brazil for the more than 800,000 people who rely on frequently out-of-stock prescriptions, including for diabetes, heart disease, and hypertension. The platform provides the supply levels of the most in-demand medications citywide and a locator tool so residents can easily identify pharmacies with available stock and get the prescriptions they need.
• A citywide data strategy and hackathons in Chattanooga, Tennessee which led to the launch of an interactive affordable housing tool that connects qualified tenants in-need to low-cost housing options and providers. This helped the city reduce the number of people experiencing homelessness by 40% and place over 3,000 residents in permanent housing. Also supported by the city’s data strategy are new artificial intelligence applications, including a 311 system that uses image detection to route residents’ photo-based issues to the right department and digital twin projects to redesign major roadways, examine mobility-related energy use, and monitor traffic and pedestrian movements to make streets safer.
• A citywide data strategy in Montevideo, Uruguay which underpinned the city’s emergency response to a severe drought crisis. The city’s data strategy enabled the municipality to rapidly assess the situation, identify safe well-water reserves, communicate with residents in real-time, and target the delivery of more than 940,000 liters of water. This included getting over 600,000 liters of water to 4,000 people at the highest risk: pregnant women, infants under six months of age, and those with immunocompromising conditions.
