The following resource is ‘a tracker of trackers’ - a compilation of  COVID-19 related research, data and other trackers from around the world, aimed at providing easy access to the rapidly growing body of knowledge being produced.
It includes cross-country research on topics including economic and social policy responses, public attitudes, politics, non-pharmaceutical interventions and media coverage.

This project is maintained by Lukas Lehner, a DPhil candidate at the Department of Social Policy at the University of Oxford.
