Tips and FAQs

Data created and maintained by the City of Cambridge is a public good and should be released to and leveraged in service of Cambridge’s residents, businesses, and institutions. Cambridge’s Open Data Program is a set of systems, technologies, and policies for maximizing the value of Cambridge’s data while simultaneously maintaining the highest possible degree of protection for privacy and security.

The open data program increases the value of city data by:

  • Releasing data in service of transparency and community engagement, so that residents understand what their city is doing.
  • Enabling city staff and the public to use the data in analyses and software applications that help Cambridge deliver services more efficiently.
  • Providing businesses and other organizations with relevant data at no cost, so that Cambridge continues to maintain a thriving local economy.
  • Removing silos between city departments, thereby fostering data-sharing and enabling efficiency improvements for city service delivery.
