Milwaukee Open Data


The City of Milwaukee's New Open Data Portal! 

May, 30 2018 

We want to change the way people engage with their government. The City of Milwaukee's Open Data Initiative is paving the way to achieve greater trust and accountability within our community. One major step we have taken towards achieving these goals is to publishing more data and reorganizing existing City data on an innovative interface now known as, The City of Milwaukee's Open Data Portal

What we love most about it:

  • A user friendly interface that allows for simplified navigation and search functions. 
  • A modern design that is responsive to mobile devices
  • An overall more effective, usable and coherent user experience for citizens to easily access and leverage open data

The new portal was launched on May, 30 2018. You are encouraged to browse, filter, graph and download city data! Is there a dataset you would like to see that is not currently published? Contact us and let us know, we'll do our best to make it available.
