The City of Madison Data initiative increases the availability of city data using open standards which will make the operation of city government more transparent, effective and accountable to the public. To encourage open access to government data, the City of Madison publishes a wide range of approved city datasets and makes them available at the City of Madison Data portal.

City of Madison is dedicated to increasing the amount and range of data sets available in the data catalog. This project is in its infancy, but will continue to grow. You can be part of this growth by suggesting datasets and by sharing innovative ways of using City of Madison data sets.
