That is 2.7% of the population,
and about 1,500,000 people overall
- up 13% from last week
- down 1% from last week
In Scotland…
1 in 40
people had Covid-19 this week

This chart is based on data from the ONS Coronavirus Infection Survey. It provides an accurate estimate of the percentage of people in each nation who have Covid-19 each week. As a quick reference, 1% = 1 in 100 people, 2% = 1 in 50, 5% = 1 in 20, ect.
By randomly testing sections of the population and then using modelling, the ONS are able to work out roughly how many people across each nation have the virus each week. For more information about the data and how it all works, you can visit here.
Please note that these figures are only estimates, and the credible intervals are not shown on this chart. It is possible that the actual figures may be a bit higher or lower than what is shown here.
If you select a week on the chart, the tooltip will tell you the exact figures for that week, in addition to the "1 in ..." figures.

This chart is based on data from the ONS Coronavirus Infection Survey. It provides an accurate estimate of the percentage of people in each age group (in England) who had Covid-19 each day over the past six weeks (42 days). As a quick reference, 1% = 1 in 100 people, 2% = 1 in 50, 5% = 1 in 20, etc.
The younger age groups are technically based on school years, but I'm showing them as the actual ages for simplicity. The first age group (2 to 11) is actually age 2 to school year 6 (age 10/11). The second age group (11 to 16) is actually school year 7 (age 11/12) to school year 11 (age 15/16). Finally, the third age group (16 to 24) is actually school year 12 (age 16/17) to age 24.

F.A.Q
Me! I’m John, a 27-year-old Cat lover and former student at the University of the Highlands and Islands (Argyll College). I started tracking the Scottish Coronavirus (Covid-19) data in a spreadsheet out of interest, which eventually led to me making this page.
Rather than buying a new domain to host it, I just added it to my ‘Travelling Tabby’ website. This is a travel blog, and has absolutely nothing to do with the Coronavirus. But still, feel free to look around if you want! (although there isn’t much on the blog, as most of my free time since the start of 2020 has been spent on this page)
If you need to contact me, you can use the contact form on this page, or email me at [email protected]
Loads! Here are some of them (Please be aware that as we move closer to the end of the pandemic, many of these sources have stopped releasing data:):

Sorry!
One issue might be that you’re using Firefox. This browser seems to break the page for a lot of people, and I have no idea what is causing it. My only suggestion would be to try viewing the page on another browser, as it just seems to be Firefox which has issues, on a range of devices.
If things in general aren’t updating, then it might just be that the page your browser is showing you hasn’t updated to show the most recent version. This seems to be an issue for only some people, for whatever reason. But if you view the page in private/incognito mode, then the issue should go away.
It’s a WordPress site, built with Elementor. That covers most of the page, but all the graphs/charts/tables are embedded from a range of different places!
These are Datawrapper, Flourish, and Everviz. The Datawrapper and Flourish charts will mention their name in the footer, and if there’s no mention, it is an Everviz chart. Oh, and the non Datawrapper maps are made with MapSVG!
I’d be happy to answer any other questions about it, but it is quite simple. I’m not really any good at programming/automation, and I’m new to all of this, so it is mostly just a lot of copying/pasting to get the website updated.
Additional Information / Clarifications
As the figures on this page are based on estimates, there is some uncertainty surrounding them. When the ONS releases these figures, they also release credible intervals, which give a range of where the true figure will be.
For example, the data for one week might say that an estimated 3.0% of England had the virus that week, with the lower credible interval being 2.9%, and the upper credible interval being 3.1%. That means that there is a 95% chance of the true figure being within that 2.9% to 3.1% range, and that 3.0% is the central estimate that has been made.
The size of the credible interval depends on the amount of data available. Larger populations have more data, and thus smaller credible intervals. But smaller populations have less data to work with, and will have higher credible intervals as a result. This means the credible intervals and level of uncertainty for Northern Ireland will be a lot larger than they are for England (For example, for the same 3.0% central estimate, Northern Ireland might have a credible interval of 2.5% – 3.5%).
I don’t display the credible intervals on this page as it triples the amount of figures I need to display and makes things harder to read, so just keep that in mind when looking at the figures (especially for smaller populations). You can see all of the credible interval figures from the ONS directly here.
While looking at this page you may see one of the top charts saying a nation/region has had an increase from last week, but the six week trend chart is clearly showing a decrease in the most recent week (or vice versa).
The reason for that is that the historical figures on the six week chart are updated each week, whereas on the other charts it is just looking at what was initially reported last week vs what has been reported this week.
So if a region reports a figure of 2.0% last week, then 2.2% this week, then the top charts will show an increase. This will be the case even if the past six weeks trend chart has revised last weeks figures up to 2.4% for that week, and shows a decline into this weeks 2.2% figure.
In brief, the Coronavirus Infection Survey works by randomly testing sections of the population with PCR tests, and then using modelling with the results to work out roughly how many people across each nation in total have the virus each week (you can read their methodology in more detail here).
In contrast, the case figures simply show how many people have reported a positive Covid-19 test each week of the pandemic.
Both sets of figures have their own uses. The Infection Survey figures are far more accurate in working out how many people in total have the virus each week. This is because not everyone who catches the virus will get tested for it to be included in the case figures (either because they didn’t want to, or because they didn’t have any symptoms and didn’t feel the need to).
The case figures are more useful when trying to view the situation at a local level, as very limited data is available for this through the Infection Survey. The case figures are also around two weeks more up to date than the Infection Survey figures, so can show the most recent trends better.
In 2022, Covid-19 testing was scaled back substantially. This affected the case figures and really hampered how useful they were. While they can still show recent trends and local hotspots, they are not as useful as they once were, and do not even nearly show the total number of cases in circulation.
Comparatively, the Infection Survey figures were not impacted in these changes in testing, so remain as accurate as before.
Below are some of the frequently requested additions for the page, with an explanation as to why they are not currently available:
Local Data
I was going to include these figures, but the ONS have now switched to only releasing the local data once a month. Plus, due to the nature of the survey (needing lots of participants), the data can only get so local while still being reliable. If you are outside of a city, chances are you will be part of a very large local area with multiple local authorities lumped together.
So I don’t think there is too much benefit in adding the local data to this page. With that being said, the ONS does release local figures once a month (usually around the middle of the month), and you can view them in their official reports here.
Age Data for Scotland/Wales/Northern Ireland
Unfortunately, the same level of age data isn’t released for the rest of the UK as it is for England. There are some figures, but they aren’t released in the most friendly to use format, and due to small population sizes the credible intervals for Scotland/Wales/Northern Ireland are normally very large.
As with the local data, I don’t think there is too much benefit in adding these figures to the page. Especially as the trend of the age figures in Scotland/Wales/Northern Ireland normally follows the same general pattern as in England. Although the ONS does release some age figures, and you can view them in their official reports here.
I aim to update this page every Friday for 6pm. Although unfortunately, this isn’t always possible due to data not being released on time, or something else in my life taking priority.
But it is updated by 6pm or shortly after most of the time! If a delay or more than 10-15 minutes is expected, I will put out a tweet to let people know.
On public holidays, the amount of data being released can vary, so the page will only be partially updated, or potentially not updated at all. I’ll include a header banner on this page to let people know when/if that is occurring.
The actual data is released by the ONS each Friday at noon.
