Collaborate, compile, and share open data for effective community-based decision making in Detroit.


This site was created to address the issue of open data sharing among Detroit's civic tech, data, and mapping community. Numerous individuals and organizations are doing great work with data, but there isn't a place where all can come together to collaborate, share data, and foster transparency together.

Open Data should be:

  • as complete as possible
  • released in open, machine-readable formats (CSV rocks!)
  • have no restrictions, non-discrimination of access
  • provided license-free
  • given appropriate citation/ attribution
  • accessible at no cost

Guidelines for Equitable Open Data in Detroit include the following:

  • Protect the people represented by the numbers
  • Do not retain personal information tied to accessing City services
  • Publish data about all City services, even for privatized “public” services
  • Prioritize the release of new datasets based on community interest
  • Increase transparency around how data sets are defined and processed
  • Engage residents offline about open data
  • Give the public a head’s up about plans for new data set releases and portal improvements so that we can be prepared to engage
