The OxCGRT systematically collects information on several different common policy responses national governments have taken in response to the COVID-19 pandemic, scores the stringency of such measures, and aggregates these scores into a common Stringency Index. Eleven indicators of government response are provided; seven indicators are policies such as school closures and travel bans, and four are financial indicators such as fiscal or monetary measures. Data are collected from public sources by a team of dozens of Oxford University students and staff from every part of the world.
