As a result, researchers have prioritized the information that their citizens can access online. tool creation and fixed-term research projects, In recent years, researchers, journalists, and civil rather than platform maintenance and long-term society have documented an increase in global data collection.

Primarily, we recommend the creation of: • Collaborative structures for data-sharing and coordination; • Processes that allow the sharing of private- sector datasets and proprietary information within trusted communities; • Funding and resources for long-term maintenance of measurement systems, and targeted support for rapid response interventions; and, • Shared resources for comparison and presentation of measurement data.
