Indicator Topics

The UNI is structured around 30 indicator topics nested across six themes. The indicator topics allow for the analysis and monitoring of different aspects of urban nature. Thanks to the flexible nature of the UNI, and given potential capacity constraints, cities are recommended to implement at least one indicator topic per theme.
