 During global health crisis, such as the one we are facing right now, the availability of timely and accurate statistics is critical to monitor the impact of the crisis on societies and the economy and inform appropriate responses. Indeed, the ability of governments to access accurate statistics can really mark the difference between countries that are successful at containing and responding to the pandemic and those that are less so. However, collecting data from traditional sources can be particularly challenging at this time. All around the world, countries are postponing their national population censuses or household surveys, either due to resource constraints in the face of COVID-19 or because face-to-face interviews cannot happen. Meanwhile, there are vast amounts of data collected in real time by private sector actors that could be helpful to monitor the impact of the pandemic on mobility, migration and on migrant slides. We're talking about data from mobile phone operators, social media and other internet-based platforms. These data have been used successfully in past health crises, such as the Ebola outbreak in West Africa, for instance, or the swine flu in Mexico. In response to COVID-19, some governments have partnered with main telecom operators in their countries to analyze anonymized data and see how mobility restrictions or social distancing measures are affecting the spread of the virus. Most of these initiatives are isolated and at all. What is really missing is a framework for collaboration with the private sector that can allow for data sharing where and when needed in ways that safeguard individual privacy and fundamental liberties. This crisis could really provide an opportunity to develop new collaborative approaches for using private data for public good.
