Couldn't agree more with this, from a recent @ChrisGiles_ story on economic literacy in the UK ft.com/content/938212…

Our job is to communicate clearly to people. If they are confused, that's on us much more than on them. Image
And no, this doesn't mean we should change our definition of things like unemployment and GDP to match what people [mis]understand, but it does mean we should provide explainers if we're using these terms when speaking to a mass audience.
It's the same in #dataviz. If someone doesn't understand my chart, that's mainly on me.

This is why we always included log scale explainers when sharing our trajectory trackers, for example.

We're hear to communicate, not to make pronouncements from on high and then walk away.
Almost without exception, people *want* to learn. Let them push at an open door instead of locking it and throwing away the key.

NEW: here’s the definitive chart on which parts of England have been hard-done-by or "let off" by the new tiers.

This one combines all the metrics the govt says it’s using:
• Cases (overall rate, rise or fall, and over-60s)
• Hospital occupancy & admissions
• Positivity rate
In summary:
• Tiers seem correct for majority of places. All high-risk areas are in highest tier
• "Harsh" decisions like Stratford typically areas whose neighbours have high risk
• Outer London has been "let off", but difficult to have outer & inner London in different tiers
The question some might ask is:

If places like Stratford were bumped up a tier because of high risk in surrounding areas, why was inner London not bumped up to tier 3 where parts of outer London appear to belong?

I think there are valid reasons, but it’s worth pondering.

NEW: here’s how England’s restriction tiers have changed from pre-lockdown

Tier 3 now runs from coast to coast across most of the north, plus Bristol, Kent & Slough.

Almost everywhere else is in Tier 2, except Cornwall, Scilly and Isle of Wight.
Some places might feel hard done by:

Inspired @carlbaker’s brilliant charts, here is a comparison of the latest case rates across areas in each tier.

👀 several outer London boroughs (Tier 2) have higher rates than places in Tier 3, such as Manchester, Leeds and Sheffield

NEW: mini-thread of maps & charts to watch for today’s UK tiers:

Here’s where we stand according to latest case data

Lots of blue on the right is good: rates falling almost everywhere. Some exceptions are outer London & south east, where rates are higher and may still be rising
Another way of looking at this is in scatter form, plotting current prevalence (horizontal) vs rate of change (vertical).

Note how inner London areas are in the bottom left: low rates and falling. But several outer London boroughs are above the average and possibly still rising
We can put that last chart into context by comparing it to how things stood on national lockdown eve.

Most areas in "very high" tier 3 had weekly rates above 400 at the time restrictions came in. Today no London borough is at that level, though parts of the south east are.

NEW: Tue 24 Nov update of Covid-19 trajectories

Main chart, including positivity rate + both hospital metrics + 5 new countries

• Poland’s peak was false: testing had dipped, so I’m now using positivity rate to judge peak prevalence
• Positivity falling in UK, ITA & ESP ✅ Image
Now UK nations & regions:
• Deaths appear to have peaked in NE & Yorks, but from the more granular data I can tell you that’s Yorks-driven. May still be rising in NE
• Cases & admissions appear to have peaked in the Midlands ✅
• Can’t clearly say southern regions peaked yet Image
Now the US state layout:

Still all eyes on the upper-midwest. Death rates in South Dakota higher than any state at any time and still climbing, but case rates in SD and neighbouring Iowa appear to have peaked.

Wyoming also concerning, and prevalence rising in most other states. Image

From today’s @ONS data we can state that week ending Nov 23 had 1,904 more deaths than the 5-year average

"But were they caused by Covid or lockdown?"
2,366 deaths involved Covid

"But did they die *of* Covid, or just *with* it?"
Covid was the underlying cause of death for 2,056
In other words, there are substantial excess deaths, and they were ~all caused by Covid-19

In fact, deaths caused by Covid are 152 *more than* total excess, suggesting the mild flu season (due in part to social distancing) is reducing other deaths and thus the overall excess
Indeed, deaths caused by flu or pneumonia have been around 100 below the 5-year average for the last couple of weeks fingertips.phe.org.uk/static-reports…

NEW: Monday 23 Nov update of Covid-19 trajectories

It’s been a while... but these are the charts I’m going to be using to track the rise and fall of autumn/winter outbreaks

This is not doom & gloom; these charts focus on highlighting when countries have passed the peak
The charts show 3 key metrics for assessing outbreak phase: cases, deaths & hospital occupancy.

You can see how cases flatten off first, then hospitalisations, and then deaths.

The Netherlands has passed all three peaks. Belgium has passed two, and deaths will stop rising soon.
Here’s the same thing in more detail, adding another metric for prevalence (positivity rate) and another for hospitalisations (admissions)

NB in all these charts I’m only showing cases from summer onwards to make sure no misleading comparisons are made between now and spring
