Codebook for the Oxford Covid-19 Government Response Tracker

Codebook version 4.0
25 July 2022

Summary of July 2022 updates

In July 2022 we adjusted our dataset to account for policies which apply to vaccinated and non-vaccinated people differently. Ten of our indicators are now split into separate variables for non-vaccinated people (eg. C1NV_School closing) and vaccinated people (eg. C1V_School closing) where policies differ between these groups. Here we refer to this as a ‘differentiated policy’. We define differentiated policies to mean policies where vaccinated people can access greater freedoms due to their vaccination status, and are subject to less stringent restrictions. An example of this is if vaccinated people who can present a vaccine pass/passport can enter public events freely, but non-vaccinated people are banned. This adjustment has resulted in changes to our ‘latest’ csv files (summarising the differentiated data), and the addition of new ‘differentiated withnotes’ files, (containing all the differentiated data). The documentation in this GitHub repository reflects these changes, and we have also published a PDF summary of the changes.

This document is the authoritative codebook for the Oxford Covid-19 Government Response Tracker (GitHub repo, university website). The dataset contains 21 indicators and a miscellaneous notes field organised into five groups (C, E, H, V, M); we also capture how policies vary based on vaccination status or geographic targeting. This codebook is divided into the following seven sections:

• Differentiation of policies by vaccine status
• Indicators for targeted policies
• C - containment and closure policies
• E - economic policies
• H - health system policies
• V - vaccination policies
• M - miscellaneous policies

For more detailed guidance about the codebook and how we interpret the indicators, see the coding interpretation guide. This ensures consistency, and standardizes coding across the database.

Updates to this codebook are recorded in the changelog below.

Differentiation of policies by vaccine status

The following ten indicators now record policies for vaccinated and non-vaccinated people: C1, C2, C3, C4, C5, C6, C7, C8, H6 and H8. The different versions we report for these 10 indicators are:

• Everyone (eg. C1E_School closing): if the same policy applies to everyone, regardless of vaccination status we report the policy as an ‘Everyone’ value. If this is the case, there will then be no values reported in the ‘Non-vaccinated’ or ‘Vaccinated’ variables, and this value is repeated in the ‘Majority’ variable.
• Non-vaccinated (eg. C1NV_School closing): if there is a requirement to present a negative test, or proof of vaccination to gain entry to optional aspects of public life (e.g., events, businesses), it is recorded as a closure to non-vaccinated people. If this is the case, we will also publish the policy that applies to vaccinated people, but there will be no value published in the ‘Everyone’ variable.
• Vaccinated (eg. C1V_School closing): if entry can be gained with just proof of vaccination, we report this as being open for people who are vaccinated. The policy may be a ‘1’ level code if significant operational differences remain, or even a ‘2’ level if vaccinated people are also required to present a negative test, as well as proof of vaccination (this is reported as a closure to reflect this stringency of policy). There will be no value published in the ‘Everyone’ variable if a ‘Vaccinated’ value is published.
  • Note: the use of the V modifier here to signal that a C or H policy applies to vaccinated people (eg. C1V_School closing) is different to the use of V to denote our V1-V4 indicators that describe specific policies about vaccine rollout (eg. V1_Vaccine prioritisation (summary))
• Majority (eg. C1M_School closing): the ‘Majority’ value reflects either the policy for everyone (E), or the policy applying to the majority of people fully vaccinated in a country, using vaccination rate data to determine if this is the vaccinated or non-vaccinated part of the population. If there are differentiated policies in place, we report the NV value if vaccination rates are under 50% in that jurisdiction, and V value if vaccination rates are above 50%, hence the majority of the population.
  • reporting the "majority" policy means that sometimes the value of an M indicator will change due to the vaccinated rate crossing the 50% value, meaning our M indicator would report the V value instead of the NV value, even though there is no change to goverenment policy on that day. To explain this, we add a note in the notes variable.
• Vaccinated or Everyone (only for C8EV_International travel controls): if there is a policy that applies to everyone (E), we include it. If there are differentiated policies in place, we publish the vaccinated (V) value for C8 in order to report the policies applying to (vaccinated) international arrivals. Because we do not have data on the vaccination rates of prospective travellers (as we do for the domestic population), we cannot publish a ‘majority’ variable. Note that this will not reflect if a country has quarantine requirements for non-vaccinated arrivals (or border closures to non-vaccinated travellers). For this information, users should refer to our differentiated withnotes file.

To summarise, depending on whether or not a country has policies differentiated by vaccine status, we will publish some combination of the following versions of each indicator.

Policy setting	E	NV	V	M / EV
The same policy applies to everyone	yes	x	x	yes
There is a differentiated policy	x	yes	yes	yes

For most indicators with differentiated policies, the M (majority, eg. C1M_School closing) variable is the only variable that provides an uninterrupted series of data; it is always populated. For C8, there is no M version, but we instead publish C8EV_International travel controls to create an uninteruppted series.

	C1	C2	C3	C4	C5	C6	C7	C8	H6	H8
Majority (M)	yes	yes	yes	yes	yes	yes	yes		yes	yes
Vaccinated or Everyone (EV)								yes

To calculate majority (M) indicators, we use the variable PopulationVaccinated. We also include another variable, MajorityVaccinated to indicate whether the majority of the population in that country/region/jurisdiction is either vaccinated or non-vaccinated people.

ID	Name	Description	Measurement	Coding
	PopulationVaccinated	Record the percentage of fully vaccinated population in the jurisdiction, or a binary indicator of majority (non-)vaccinated, depending on data availability. We primarily source this data from Our World In Data’s 'fullyvaccinatedperhundred' data series	Percentage OR binary indicator	Number - the proportion of the population that is reported as vaccinated by that jurisdiction Under 50%* - the majority of the population is unvaccinated (used in jurisdictions where we do not have regular vaccination rate data) Over 50%* - the majority of the population is vaccinated (used in jurisdictions where we do not have regular vaccination rate data) Blank - no data
	MajorityVaccinated	Record a binary indicator of majority (non-)vaccinated. We primarily source this data from Our World In Data’s 'fullyvaccinatedperhundred' data series	Binary indicator	NV - the majority of the population is unvaccinated (used in jurisdictions where we do not have regular vaccination rate data) V - the majority of the population is vaccinated (used in jurisdictions where we do not have regular vaccination rate data) Blank - no data

* The binary indicator applies specifically to Chinese and Indian subnational units. While for Chinese subnational units there is a lack of provinces vaccination data availability, for Indian subnational units such data is available but not consistent as a time series. We thus use the national vaccination rates to indicate whether the majority of population was fully vaccinated in Chinese provinces, and the subnational vaccination date in which vaccination with two doses (fully vaccinated people) crossed 50% in Indian states.

Indicators for targeted policies

Most indicators are recorded on an ordinal scale that represents the level of strictness of the policy. Four of the indicators (E3, E4, H4 and H5) are recorded as a US dollar value of fiscal spending. V1 records categorical data and the ranked order of prioritised groups for vaccination in a population.

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 small part of the population. If the most stringent policy is only present in a limited geographic area or sector (e.g. perhaps only one state has implemented policies at a high level), 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).) E1 has a flag to describe whether income support is for just formal sector workers (flag=0) or whether it includes informal workers as well (flag=1). H7 has a flag to describe whether vaccine policy is funded at cost to the individual (flag=0) or by government (flag=1).

As explained in our index methodology documentation, an indicator with flag=0 is weighted lower than flag=1 when calculating overall index values.

We have 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 are not being actively updated beyond August 2021.
