Things to note:
• Daily covid data is extremely noisy and implies false precision
• This is why we use a rolling average. Watch for general trends. Focus on slopes, not specific daily numbers
• Read Tuesday’s thread for more on this

We’ve also changed our data sourcing recently.

I’m no longer happy using Worldometers, so now sourcing all data directly from official country sources (health ministries etc).

This takes longer, but given my concerns over data quality on covid, I think this is important.

Here’s a video where I explain why we’re using log scales, showing absolute numbers instead of per capita, and much more:

And a new chart showing why we're using absolute numbers rather than population-adjusted rates:

Please email [e-mail] with feedback, requests & subnational data.

All of these are invaluable, and we incorporate your suggestions and data every day.

We’ll keep getting back to as many people as possible.

Goodnight, one and all :-)

And I do mean the above. We reply to 100s of queries each week and take on board all feedback. In fact that’s now pretty much a full time job!

These charts cover a complex & critical subject, and there are dozens of legitimate questions to be asked of them. Please keep asking 🙂
