COVID-19 Government Response Tracker

Governments are taking a wide range of measures in response to the COVID-19 outbreak. This tool aims to track and compare policy responses around the world, rigorously and consistently.

About the project

The Oxford Covid-19 Government Response Tracker (OxCGRT) collects systematic information on policy measures that governments have taken to tackle COVID-19. The different policy responses are tracked since 1 January 2020, cover more than 180 countries and are coded into 23 indicators, such as school closures, travel restrictions, vaccination policy. These policies are recorded on a scale to reflect the extent of government action, and scores are aggregated into a suite of policy indices. The data can help decision-makers and citizens understand governmental responses in a consistent way, aiding efforts to fight the pandemic. Our core working paper (BSG-WP-2020/032) provides more information on methodology and data collection.

Latest insights

  • New: Updated working paper on Chinese provincial government responses. This working paper (BSG-WP-2021/041-v2.0) investigates patterns in government responses to the Delta waves and the threat of Omicron variant and trends in vaccination and international travel policy in China.
  • Data on vaccination policies available. Official vaccination prioritisation lists (V1), which population groups are receiving vaccines (V2), and the cost of vaccination to the individual (V3) have now been added to the main data. This was in partnership with Oxford Martin School. See the full vaccine dataset CSV (includes all 50 categories) and the main CSV (with nine summary indicators added). 
  • Global Dashboard on Vaccine Equity. Data from the tracker is integral part of a new joint initiative from UNDP and WHO, which combines the latest COVID-19 vaccination information with the most recent socio-economic data to illustrate why vaccine equity is critical to saving lives and to driving a fairer recovery.

Our data

Download the latest datasets and timeseries data and read about the different versions of the dataset.

Refer to our codebook and coding interpretation guide when consulting or using our datasets.

Our core working paper (BSG-WP-2020/032) provides more information on methodology and data collection. The data is collected by a team of hundreds of volunteers around the world from the Oxford community and is updated continuously. We produce monthly regional reports providing a snapshot of shifts in government responses to COVID-19.


OxCGRT collects publicly available information on 23 indicators of government response:

  • Containment and closure policies (indicators C1-C8) record information on containment and closure policies, such as school closures and restrictions in movement.
  • Economic policies (indicators E1-E4) record economic policies, such as income support to citizens or provision of foreign aid.
  • Health system policies (indicators H1-H8) record health system policies such as the COVID-19 testing regime, emergency investments into healthcare and most recently, vaccination policies.
  • Vaccine policies (indicators V1-3) record vaccination policies: a country’s prioritisation list, eligible groups, and the cost of vaccination to the individual. This was in partnership with Oxford Martin School.

Please note: we have recently stopped updating data on our E3, E4, and H4 fiscal indicators. The data for these indicators will still be present in the CSV files, but they just are not being actively updated beyond August 2021. We do still plan to actively keep the H5 fiscal indicators (government investment in vaccine research) updated over time.

Policy indices

To help make sense of the data, we have produced four indices that aggregate the data into a single number from 0-100. This is a measure of how many of the relevant indicators a government has acted upon, and to what degree. The index cannot say whether a government's policy has been implemented effectively. For more information refer to our index methodology.

  • Overall government response index
    The index records how the response of governments has varied over all indicators in the database, becoming stronger or weaker over the course of the outbreak. It is calculated using all ordinal indicators.
  • Containment and health index
    The index combines ‘lockdown’ restrictions and closures with measures such as testing policy and contact tracing, short term investment in healthcare, as well investments in vaccines. It is calculated using all ordinal containment and closure policy indicators and health system policy indicators.
  • Stringency index
    The index records the strictness of ‘lockdown style’ policies that primarily restrict people’s behaviour. It is calculated using all ordinal containment and closure policy indicators, plus an indicator recording public information campaigns.
  • Economic support index
    The index records measures such as income support and debt relief. It is calculated using all ordinal economic policies indicators.
  • Risk of openness index
    The index is based on the recommendations set out by the World Health Organization (WHO) of the measures that should be put in place before Covid-19 response policies can be safely relaxed. Read more about the details, visualisations, and methodology. Read the dedicated Risk of openness working paper.

Note that these indices simply record the number and strictness of government policies, and should not be interpreted as ‘scoring’ the appropriateness or effectiveness of a country’s response. A higher position in an index does not necessarily mean that a country's response is ‘better’ than others lower on the index.

Subnational data

In addition to country-level data, our primary datasets additionally include some subnational data. So far we have incorporated data for Brazilian states, Canadian provinces and territories, Chinese provinces, UK devolved nations, and US states into the primary dataset.

Subnational data can be interpreted using our main codebook and our subnational data interpretation guidance.


You can view interactive data visualisations of country data or heat map over time. The most recent versions of charts and maps are all available on Github.

Interactive visualisations of each policy indicator are available at Our World in Data.



Please note: this is an ongoing collation project of live data. If you see any inaccuracies in the underlying data, or for specific feedback on the analysis or another aspect of the project please contact us. The database was upgraded on 25 April and you can read the full details of what's changed as well as view the archived version of this dataset on GitHub.

Indicators and indices

I would like to find out more detail about the policies in place. How can I find out why the code has changed?
Our ‘WithNotes’ CSV provides all of the notes recorded for each policy change.

What different policies do you collect data on?
We collect data on a range of policies, including school closures, stay at home orders, economic support for households, and vaccination policy. You can find details of how we code these in our codebook.

What is the Stringency Index and how is it calculated?
The Stringency Index is an aggregate score/composite measure made up of a particular combination of policy indicators/response metrics from the codebook and their values (for the Stringency Index these are C1-8 and H1). The OxCGRT aggregates these policy indicator values into a common “Stringency Index” that runs from 0 -100. Our methodology documentation explains how this is calculated.

Does a higher Stringency Index score mean a country is doing better?
The Stringency Index simply records the number and strictness of government policies and should not be interpreted as ‘scoring’ the appropriateness or effectiveness of a country, region, or territory’s response to the COVID-19 pandemic.

How many aggregate indices do you have? 
We have four, and each is formed from a different combination of indicators. Stringency Index, Government Response Index, Containment and Health Index, Economic Response Index. You can see which indicators are included in the table in this methodology document.

The data

Where can I download the data? 
All of our data is available here on our Github page in CSV format. We also have more detailed subnational data available on Github.

There are lots of datasets, what is the difference between them?

  • Timeseries: Policies arranged with dates as column names. Each indicator and index is a separate worksheet in timeseries.xlsx.
  • Latest: all countries and subnational jurisdictions with all indicators.
  • Latest_all_changes: highlights changes in this order: Previous Policy - Current Policy - Current Note - Note used to change policy.
  • Latest_combined: latest with policies recorded as 1G, 2G etc instead of separate Policy (1, 2, 3 etc) and Flag (0/1) columns.
  • Latest_all_responses: duration of policy codes for a country along with initial note. Sorted by PolicyType - PolicyCode - Start Date - End Date - Initial Note.
  • Latest_with_notes: all countries and subnational jurisdictions with all indicators, notes, and citations.

Do I need permission to use the data?
The data is all freely available to download and use, as long as you cite the tracker accordingly as follows:

  • Credit for media use: Oxford COVID-19 Government Response Tracker, Blavatnik School of Government, University of Oxford.
  • Recommended reference for academic publications: Thomas Hale , Noam Angrist , Rafael Goldszmidt, Beatriz Kira , Anna Petherick , Toby Phillips, Samuel Webster, Emily Cameron-Blake , Laura Hallas, Saptarshi Majumdar, and Helen Tatlow. (2021). “A global panel database of pandemic policies (Oxford COVID-19 Government Response Tracker).” Nature Human Behaviour.

I only want data for a few countries or dates but the data download includes all of them, is there a way around this?
We recommend that you download the data, and use Excel or Google sheets to delete columns or rows that are not needed. Using a filter is helpful for this.

How do I download the data from Github?
Go to the Github data download page, click 'view raw', then right hand click and select 'save as', and save in the format 'comma-separated values'. You can then upload this .csv file to Excel or Google Sheets as a spreadsheet. You can apply a filter to select the countries and columns that you need.

Do you have subnational data available?
Yes, we publish subnational data on the UK devolved nations, Canadian provinces and territories, US states, and Brazilian states and major cities.

Why is the value for a particular country/region/territory so high when I know that restrictions are currently low nationally?
Government coronavirus policies often vary by region within countries. We code the most stringent government policy that is in place in a country/territory, as represented by the highest ordinal value. Sometimes the most stringent policy in a country/territory will only apply to a limited geographic area or sector and we use a binary flag variable to denote this limited scope. Ten of the indicators (C1-C7, H1, H6 and H8) have a flag for whether they are "targeted" to a specific geographical region (flag=0) or whether they are a "general" policy that is applied across the whole country/territory (flag=1). For instance, if only one state in the USA has implemented policies at the highest level of stringency, but the rest of the country doesn’t have similar policies, we record the most stringent policy, and add a targeted flag. This is the situation reflected in the data.

Why have the values that I downloaded last week changed? 
Some indicators (and therefore, index values) will be changed retroactively. We aim to have a second pair of eyes review every data point in the OxCGRT. Inevitably, some things may be tweaked in this review process, leading to changes to past dates. We recommend you frequently download fresh data from OxCGRT, rather than relying on an old export.

Is there a more immediate way to visualise the data?
The team at Our World in Data present our live data in the choropleth maps on their page.

When is the data updated? 
We update the data in weekly cycles, so if a country/region/territory changes a policy, it may take a few days for this to be reflected in the database.
