The Oxford COVID-19 Government Response Tracker (OxCGRT) is a global database that provides continuously updated, comparable information on government policies related to the COVID-19 pandemic. It covers over 180 countries and subnational jurisdictions, tracking 19 policy areas on ordinal or continuous scales. The data include composite indices that measure the extent of government responses, enabling researchers and policymakers to analyze the impact of policies on disease spread, economic outcomes, and social welfare. OxCGRT is built by a team of over 400 volunteers who collect and code data in real time, ensuring consistency through training and weekly meetings. The data are published in multiple time-series formats, allowing for easy access and use by non-experts and researchers alike. OxCGRT has been widely used to study the effects of government responses to the pandemic, revealing patterns in the timing and sequencing of policy adoption and easing. It has been combined with behavioral and epidemiological data to explore how policies influence human behavior and disease transmission. The data have been used to analyze the impact of policies on healthcare resources, disease incidence, air pollution, political regimes, and economic outcomes. The database also includes detailed notes and source links, supporting detailed interpretation of specific policies. OxCGRT's design emphasizes comparability, legibility, and transparency, with data available in multiple formats and updated continuously. The data are used to analyze the effects of policies on disease spread, economic welfare, and other outcomes of interest. The database includes four composite indices: the Government Response Index (GRI), the Containment and Health Index (CHI), the Stringency Index, and the Economic Support Index (ESI). These indices provide a snapshot of the number and degree of policies in place in a given area. OxCGRT has been used to study the timing and sequencing of policy adoption, the relationship between policies and human behavior, and the effectiveness of different policy measures. The data have been combined with mobile phone mobility data to relate policies to human behavior and to explore the potential for integrating OxCGRT data with other sources. The database has also been used to analyze the effects of policies on economic and social outcomes, including the impact of working from home on sectoral structures and the effects of policy responses on economic growth. OxCGRT is a valuable resource for researchers and policymakers, providing a comprehensive and systematic record of government responses to the pandemic. It enables the analysis of the effects of policies on disease spread, economic outcomes, and social welfare, and supports the development of evidence-based policy decisions. The database is continuously updated and available for use by researchers and policymakers worldwide.The Oxford COVID-19 Government Response Tracker (OxCGRT) is a global database that provides continuously updated, comparable information on government policies related to the COVID-19 pandemic.
