From the Key Findings: " 48 countries have a high risk of democratic declines during the Covid-19 [coronavirus disease 2019] pandemic and 34 countries are at medium risk.  The Pandemic Backsliding Risk Index tracks government responses to Covid-19 and uses V-Dem [Varieties of Democracy] data to factor in the general risk of democratic declines.  47 countries are not at risk of pandemic backsliding demonstrating that responding to the pandemic is possible without jeopardizing democratic standards."
