The City Data Alliance helps mayors around the world harness the power of data to improve their communities. Mayors from cities in Arizona, Louisiana, Texas, Chile, Mexico, and Canada share how being a part of this collective has impacted their residents.

Bloomberg Philanthropies announced that 20 mayors from North and South America will join the Bloomberg Philanthropies City Data Alliance. As part of the Alliance, the mayors will receive executive education and coaching on how to leverage data to strengthen city government operations, innovate public services, and produce better outcomes for residents including improving access to health care, reimagining waste management systems, expanding affordable housing, or combatting homelessness. To kick off their participation, the 20 mayors—representing 11 U.S. and 9 Latin American cities—met with Michael R. Bloomberg and renowned data leaders in academia, innovation, urban governance, social impact, and racial equity at Johns Hopkins University over the course of a three-day immersion.
