- Open Spending Portal in Austria

The Austrian open spending portal holds spending and budget data of all Austrian municipalities. The mayors were provided with access data to the portal in order to view the visualisations of their spending data (2001-2013). With two simple clicks, not only the data can be published, but also the interactive visualisations. Currently (March 2015) more then 740 municipalities have made use of this free service.

The following features are available on the portal:

  • Visualisation of the spending and budget data according to political categories (spending areas, such as "education", "health"...) as an interactive treemap as well as the spending history (2001-2013). Budget data for current/upcoming years can be added by the municipalities

  • Economic overview of the spending data according to cross-sectional aspects (spending types, such as "personnell costs", "tax revenues"...) including the result according to Maastricht critera.

  • Both visualisations are interactive and can be drilled down to three levels (e. g. "Educatioin" -> "Pre-School Education" -> "Kindergarten".)

  • Visualisation "Where does the tax money go?" that shows where tax monex has to be used from statistically 1.000 Euros of tax revenues of a city.

  • Visualsation of the "KDZ Quick Test" - a systemantic approach of the financial soundness of the municipality according to 5 sub-indicators

  • Download of the data sets accoring to Open Government Data standards (CSV files)

Furthermore, the municipalities have the possibility to

  • View all the visualisations and make them publicly available with a few simple clicks
  • Upload data from their own financial systems (e. g. planned budgets), explanatoriy PDF documents, links to their own Websites with further resources
  • Add comments to the visualisations, to further explain circumstances
  • Include the visualisations in their own websites with special iFrame versions
  • Special tool for comparing their own spending with 2-3 other municipalities
