Covid Update: 31 August

A brief bit of housekeeping, your author will be taking a brief holiday during which I won’t be posting. But I should return to posting next week.

Last week we looked at some relatively good news in terms of the spread of Covid-19 in the states of Pennsylvania, New Jersey, Delaware, Virginia, and Illinois. We had been watching some recent data that suggested some of the five states had begun to see a real and measurable slowdown in the rate of increase of new cases.

Where are we this week? Did those trends continue?

Kind of…

Starting with the bad news, we have Virginia. Old Dominion is now in the throes of a Covid wave worse than what it saw back in the Spring, and fast nearing the heights—maybe depths—of the winter wave. That wave peaked just under 6,200 new cases per day. (And fell to as low as 129 per day in mid-June.) Presently Virginia reports just under 3,200 new cases per day, or nearly half that previous peak. Unfortunately, we do not yet see any significant decline in the rate at which those case numbers have increased. The line in the graphic above is no longer curving upwards, instead you can describe it as more a straight line.

Somewhere below Virginia in that it’s not bad news, but it’s also not great news, we have Delaware and Illinois. In both states the unfortunate news remains that new cases continue to increase. But at present we can also see that new cases have begun to slow. In these states the curves have begun to flatten out, though they still tilt positive.

Contrast that to New Jersey, where we have good news. The Garden State looks similar to Delaware and Illinois, but the difference is the curve in New Jersey may have peaked. The line is now tilted negative. Of course, this is a very recent development and we would want to see this trend continue for a week or so before we begin to speak of New Jersey’s wave cresting.

But between New Jersey, Delaware, and Illinois, I would not be surprised if by the end of next week we begin to see new cases peaking and beginning to decline.

But what about Pennsylvania? Initially I would have placed the Commonwealth with Delaware and Illinois as it clearly had not peaked, but it did exhibit evidence that its curve was beginning to flatten. In recent days, however, as one can clearly see in the chart, the average has begun to shoot back up again. But as I cautioned last week, that’s not uncommon. Consequently, I want to see another week’s worth of data before we begin to talk about what direction Pennsylvania is taking.

In all this though, we do have one wildcard. This weekend we in the United States begin our Labour Day holiday. Will Labour Day gatherings and parties lead to increased spread of the virus? Will we have super-spreader events? Unfortunately we will not know for about a week or week and a half after the holiday.

As all this has been happening, we also have the death rate.

Death curves for PA, NJ, DE, VA, & IL.

Last week I noted that we had begun to see rising numbers of deaths. This made sense given that deaths lag behind new cases. Early in the pandemic it often—not always—took a few weeks before people needed hospitalisation. Then a few weeks later is often—not always—when people would die. So a few weeks after the fourth wave began to take hold we continue to see rising numbers of deaths in all five states.

In Virginia and Illinois we see two of the most significant increases. In fact in the third wave, Illinois peaked at just under an average of 32 deaths per day. As of Tuesday the seven-day average was at just over 25. And with the current trend pointing towards increasing death, it’s possible we could see the fourth wave be more lethal in Illinois than the third.

Compare that to Virginia. Old Dominion saw a smaller death rate in the third wave, peaking at 18 deaths per day. However, just yesterday the state reached an average of 21 deaths per day. In other words, Virginia’s fourth wave has become more lethal than its third wave. Unfortunately, like in Illinois we continue to see deaths climbing and there is no evidence yet that deaths are slowing down.

In the tri-state area we see some slightly better news by comparison. In Pennsylvania and New Jersey deaths remain below their third wave peak. For example, in the third wave, Pennsylvania peaked at nearly 50 deaths per day. Yesterday the average was just below 20. Despite both states being below their third wave peaks, however, deaths do continue to climb.

Delaware is the exception here. With such a small population, it reached a third wave peak of about two deaths per day. At present it’s just reached three. But I would not say that three is significantly greater than two.

Overall, however, I expect to see deaths continue to climb over the next week or two until these slowing rates of new cases begin to create slowing death rates. And so I am hopeful that in the coming few weeks we will begin to see the new case rates slow, peak, and begin to decline by about mid-September. That’s more likely in places like New Jersey, Delaware, and Illinois, but if we’re lucky those patterns or similar will soon begin to emerge in Pennsylvania and Virginia.

Big Beer

A few weeks back, a good friend of mine sent me this graphic from Statista that detailed the global beer industry. It showed how many of the world’s biggest brands are, in fact, owned by just a few of the biggest companies. This isn’t exactly news to either my friend or me, because we both worked in market research in our past lives, but I wanted to talk about this particular chart.

Not included, your home brew

At first glance we have a tree map, where the area of each “squarified” shape represents, usually, the share of the total. In this case, the share of global beer production in millions of hectolitres. Nothing too crazy there.

Next, colour often will represent another variable, for market share you might often see greens or blues to red that represent the recent historical growth or forecast future growth of that particular brand, company, or market. Here, however, is where the chart begins to breakdown. Colour does not appear to encode any meaningful data. It could have been used to encode data about region of origin for the parent company. Imagine blue represented European companies, red Asian, and yellow American. We would still have a similarly coloured map, sans purple and green,

But we also need to look at the data the chart communicates. We have the production in hectolitres, or the shape of the rectangle. But what about that little rectangle in the lower right corner? Is that supposed to be a different measurement or is it merely a label? Because if it’s a label, we need to compare it to the circles in the upper right. Those are labels, but they change in size whereas the rectangles change only in order to fit the number.

And what about those circles? They represent the share of total beer production. In other words the squares represent the number of hectolitres produced and the circles represent the share of hectolitres produced. Two sides of the same coin. Because we can plot this as a simple scatter plot and see that we’re really just looking at the same data.

Not the most interesting scatter plot I’ve ever seen…

We can see that there’s a pretty apparent connection between the volume of beer produced and the share of volume produced—as one would (hopefully) expect. The chart doesn’t really tell us too much other than that there are really three tiers in the Big Six of Breweries. AB Inbev is in own top tier and Heineken is a second separate tier. But Carlsberg and China Resources Snow Breweries are very competitive and then just behind them are Molson Coors and Tsingtao. But those could all be grouped into a third tier.

Another way to look at this would be to disaggregate the scatter plot into two separate bar charts.

And now to the bars…

You can see the pattern in terms of the shapes of the bars and the resulting three tiers is broadly the same. You can also see how we don’t need colour to differentiate between any of these breweries, nor does the original graphic. We could layer on additional data and information, but the original designers opted not to do that.

But I find that the big glaring miss is that the article makes the point despite the boom in craft beer in recent years, American craft beer is still a very small fraction of global beer production. The text cites a figure that isn’t included in the graphic, probably because they come from two different sources. But if we could do a bit more research we could probably fit American craft breweries into the data set and we’d get a resultant chart like this.

A better bar…

This more clearly makes the point that American craft beer is a fraction of global beer production. But it still isn’t a great chart, because it’s looking at global beer production. Instead, I would want to be able to see the share of craft brewery production in the United States.

How has that changed over the last decade? How dominant are these six big beer companies in the American market? Has that share been falling or rising? Has it been stable?

Well, I went to the original source and pulled down the data table for the Top 40 brewers. I took the Top 15 in beer production, all above 1% share in 2020, and then plotted that against the change in their beer production from 2019 to 2020. I added a benchmark of global beer production—down nearly 5% in the pandemic year—and then coloured the dots by the region of origin. (San Miguel might not seem to fit in Asia by name, but it’s from the Philippines.)

Now I can use a good bar.

What mine does not do, because I couldn’t find a good (and convenient) source is what top brands belong to which parent companies. That’s probably buried in a report somewhere. But whilst market share data and analysis used to be my job, as I alluded to in the opening, it is no longer and I’ve got to get (virtually) to my day job.

Covid Update: 23 August

Last week I mentioned how there was some initial evidence showing the rapid, near-exponential spread of the virus was beginning to slow down. One week later, where are we?

The good news is that those initial signals do appear to be true, i.e. not noise. You can see it if you look at the very end of the charts for all but Virginia.

New case curves for PA, NJ, DE, VA, & IL.

We can see the slowing spread rate most easily in Illinois and New Jersey. The shape of the curve now resembles more like the top of a hill rather than the beginning of a roller coaster. To be clear, this doesn’t mean Covid-19 is no longer spread—that is not the case at all. Rather, just the speed at which people are spreading the virus has slowed from that initial rapid acceleration.

In the last week, however, despite the good news for Illinois, we can also see that this fourth wave, driven by the Delta variant, has now exceeded the third wave we saw earlier this spring. Virginia still remains the only other state joining Illinois in that auspicious category, but Delaware is edging ever closer.

However, Delaware as well as Pennsylvania can both join Illinois and New Jersey in seeing slowing rates, though it’s not nearly as evident as in the other two states. Delaware continues to approach its third wave peak.

Virginia is the one state where we might just now be seeing the beginning of a slowdown. Though it’s probably the hardest state in which to see it. Yesterday, after a weekend of no data updates, the state reported over 7,000 new cases. That’s bad. But jumping from 5,900 new cases last Monday to yesterday’s 7,100 is comparatively good. Compare Monday to Monday, four weeks ago the increase was 91%. Three weeks ago it was 88.8%. Three weeks ago it fell to 30.9%. And then two weeks ago it was 26.8%. Yesterday’s increase was only 20%. Again, not great, but that’s a slowdown.

The hope in all five states is that we can begin to actually peak perhaps in early- to mid-September before the seven-day average begins to decline. The question then will be what do things look like as begin to head into flu season, which is when last winter’s deadly surge began in earnest.

What about deaths though?

Death curves for PA, NJ, DE, VA, & IL.

Last week I discussed how we were seeing death rates hold fairly steady with only small increases to the seven-day averages. Unfortunately this past week we saw more significant increases. Nothing too dramatic, to be clear, but increases all the same.

Take Pennsylvania, for example. Two weeks ago we went from an average of 7 deaths per day due to Covid-19 to just 9 last week. But yesterday that number jumped up to 16. Illinois, which had went from 12 to 13, climbed from 13 to 20 as of yesterday.

This is also not terribly surprising. As we are now several weeks into this wave, we would expect to see hospitalisations increase, which we had been seeing, before, sadly, deaths followed suit. We may now be entering that phase where deaths, again, a lagging indicator, begin to rise.

I do not think, however, that we will see numbers near to the extremes we saw this past winter. Even to reach levels we saw this past spring will be difficult. However, I’d be remiss if I didn’t point out that Illinois has reached nearly half its third wave peak number of deaths.

We will need to continue observing these death rates over the coming week to see if they continue to increase. I suspect they will before, like new cases, they begin to slow down before then peaking.

Rarely Shady in Philadelphia

After a rainy weekend in Philadelphia thanks to Hurricane Henri, we are bracing for another heat wave during the middle of this week. Of course when you swelter in the summer, you seek out shade. But as a recent article in the Philadelphia Inquirer pointed out, not all neighbourhoods have the same levels of tree cover, or canopy.

From a graphics standpoint, the article includes a really nice scatter plot that explores the relationship between coverage and median household income. It shows that income correlates best with lack of shade rather than race. But I want to focus on a screenshot of another set of graphics earlier on in the article.

On the other hand, pollen.

I enjoyed this graphic in particular. It starts with a “simple” map of tree coverage in Philadelphia and then overlays city zip codes atop that. Two zip codes in particular receive highlights with bolder and larger type.

Those two zip codes, presumably the minimum and maximum or otherwise broadly representative, then receive call outs directly below. Each includes an enlarged map and then the data points for tree cover, median income, and then Black/Latino percentage of the population.

I don’t think the median income needs to be in bar chart form here, especially given the bars do not line up so that you can easily compare the zip codes. The numbers would work well enough as factettes or perhaps a small dot plot with the zip codes highlighted could work instead.

Additionally, the data labels would be particularly redundant if a small scale were used instead. That would work especially well if the median income were moved to the lowest place in the table and the share charts were consolidated in one graphic. Conceptually, though, I enjoy the deep dive into those two zip codes.

Then I wanted to highlight some great design work on the maps. Note how in particular for Chestnut Hill, 19118, the outline of the zip code is largely in a thicker, black stroke than the rest of the map. At the upper right, however, you have two important roads that define the area and the black stroke breaks at those points so the roads can be clearly and well labelled. The other map does the same thing for two roads, but their breaks are shorter as the roads run perpendicular to the border.

Overall this was just a great piece to read and I thoroughly enjoyed the graphics.

Covid Update: 16 August

In last week’s update we looked at how in Pennsylvania, New Jersey, Delaware, Virginia, and Illinois the numbers of new cases of Covid-19 were trending in the wrong direction. This past week they continued to do much the same.

This week I want to begin with New Jersey, because last week I noted how the growth in the number of new cases was holding steady. In other words, the number of new cases, whilst growing, was growing by roughly the same number of cases each day. We contrasted that with the other four states where we witnessed increasing numbers of new cases each day.

New case curves for PA, NJ, DE, VA, & IL.

New Jersey’s continued to see similar growth, fairly flat, though it has increased ever so slightly. And in the other states we continue to see increasing numbers of new cases, but that accelerating growth may be tailing off. That doesn’t mean we are seeing new cases decline—far from it. Instead we are seeing the number of new cases become slightly smaller each day. And if you look ever so closely at the tails of each chart above, you can see how the slope of the line, the seven-day average, is no longer bending upward but is straightening out to a line instead of a curve or, in some cases, maybe even beginning to flatten out as one does as one would approach a peak.

This doesn’t mean we are at the point of seeing this fourth wave peak, but the first indication of such a thing happening would be a slowdown in the numbers of new cases. And so moving forward over the next two weeks or so, we’ll want to see if that continues.

In absolute terms, I mentioned last week that I wouldn’t be surprised if Illinois surpassed its springtime seven-day average peak of 3390 new cases per day. Fortunately, we haven’t yet hit that milestone. We are, however, just under 200 new cases per day away from that. This can speak to that slight slowdown in the numbers of new cases.

We also looked at how in the tri-state area all three states were well below their springtime peaks. That continues to be the case. However, Delaware is nearing that peak.

When we look at deaths, we also see very much the same story as last week.

Death curves for PA, NJ, DE, VA, & IL.

Delaware continues to be the exception where we saw deaths climb by just one. But when we look at the other four states, the concern last week was Illinois where we saw a significant jump in the rate. Fortunately that has slowed down over the past week and deaths climbed from 12 per day to just 13 per day. Similarly, the rate in Pennsylvania and Virginia has also slowed down slightly with 9 and 7 people dying each day in those states, respectively.

The good news is in New Jersey. There the death rate has slowed so much so that the average hasn’t changed. Last week it was 6 per day. As of yesterday’s data update, it’s still sitting on 6.

And we need to mention again that these deaths and the hospitalisations that we don’t track are almost all happening solely in the unvaccinated population. If you haven’t been vaccinated yet, you really need to. Because these vaccines have been proven safe; they’ve been proven effective; and they’re free if you’re worried about cost.

The Pandemic of the Unvaccinated

Get your shots.

It’s pretty much that simple. But for just under half the country, it’s not getting through. So I went looking for some data on the breakdown of Covid-19 cases by vaccinated and unvaccinated people.

I found an analysis by the Kaiser Family Foundation (KFF), a non-profit that focuses on health and healthcare issues. They collected the data made available by 24 states—not all states provide a breakdown of breakthrough cases—and what we see across the country is pretty clear. If you want more details on their methodology, I highly recommend you check out their analysis.

Breakthrough cases

In all but Arizona and Alaska, vaccinated people account for less than 4% of Covid-19 cases. In most of these states, it’s less than 2%. For the states that we regularly cover here—Pennsylvania, New Jersey, Delaware, Virginia, and Illinois—we have New Jersey, Delaware, and Virginia represented in the data set.

Delaware leads the three with vaccinated people accounting for just 1% of Covid-19 cases. Virginia is 0.7% and New Jersey is just 0.2%. In other words, in New Jersey almost nobody vaccinated is catching Covid-19 over the observation period.

And when we look at the vaccinated population, we can see what breakthrough events—cases, hospitalisations, and deaths—they are experiencing.

In almost all states, less than 0.5% of vaccinated people are getting Covid-19. Only in Arkansas do we see a number greater than that: 0.54%. In no state do we have more than 0.6% of vaccinated people requiring hospitalisation. And with that number so low, it won’t surprise you that in no state do we have more than 0.01% of vaccinated people dying.

In other words, the rapidly climbing numbers of new cases and slowly rising deaths that we looked at yesterday, that’s almost all in people who haven’t yet gotten vaccinated.

Get your shots.

Covid Update: 9 August

Late last week I provided a brief update on the Covid-19 situation in Pennsylvania, New Jersey, Delaware, Virginia, and Illinois. Today I wanted to circle back to my statement that I’d update everyone again early this week. Of course, we had to wait until states began reporting their Monday data to get a better sense of where we are at in terms of new cases and deaths.

Spoiler: nowhere good.

Let’s start, as usual, with new cases.

New case curves for PA, NJ, DE, VA, & IL.

We can see just from the tail end of the charts above that new case growth is accelerating in nearly all five states. Nearly because New Jersey’s growth has remained fairly constant, in other words the number of new people getting infected is not becoming larger each day but remaining relatively flat. That said, compared to 28 July, my last more thorough update, the seven-day average for new cases is still up by 66%.

In the other four states we see accelerating growth, i.e. the number of people infected grows daily. Virginia and Illinois are perhaps in the worst positions. Consider that earlier this spring during the Third Wave, Virginia peaked with a seven-day average of 1615 new cases per day. Yesterday the seven-day average reached 1625. This Fourth Wave is making more people sick now than they were in the spring. Illinois is not yet at the peak of its Third Wave, 3390 new cases per day, but yesterday the Land of Lincoln reached 2713. It’s not far from that ugly benchmark. Can Illinois’ seven-day average see an increase of about 600 new cases per day in a week? Consider that one week ago the average was at 1914. That’s an 800-new case increase. I would expect that if my next update is next Tuesday we will find Illinois in a worse position now than it was in this past spring.

What about the last two states of the tri-state area? Fortunately—for now—both Pennsylvania and Delaware remain below, roughly by half or so, their springtime peaks during the Third Wave. In part, that’s because—along with New Jersey—the Northeast has some of the highest rates of vaccination. But none of those states are near the levels we would need for herd immunity, especially given the increased transmissibility of the Delta variant.

In Pennsylvania the seven-day average for new cases is now just shy of 1500 new cases per day. Interestingly, if we halve the Monday data that includes both Sunday and Monday the daily numbers of new cases have declined for five consecutive days. I wouldn’t expect that trend to continue given the rampancy with which Delta is spreading throughout the Commonwealth, but that would be the signal in the data we would be looking for when this Fourth Wave breaks.

Delaware reports much the same. Cases are significantly up, but now so much so as to outpace the Third Wave. The First State’s seven-day average now sits at 185 new cases per day, but for the past four days the daily number has exceeded 200. Unlike Pennsylvania, that’s not the signal we would want to see to give us a sense the wave might be breaking.

What about deaths? Last week I mentioned we were seeing those numbers begin to creep back up despite falling during the initial weeks of the Delta wave.

Death curves for PA, NJ, DE, VA, & IL.

The tail ends here, with the exception of Illinois, are far harder to see. In Illinois, on 28 July the seven-day average for deaths bottomed out at 4 deaths per day. Deaths have climbed ever since, tripling to 12 deaths per day. Prior to yesterday, the state had seen double-digit daily deaths for five consecutive days for the first time since early June. These are signs that deaths are heading in the wrong direction. But if we want to try and find a glimmer of hope, those deaths started at 18 on 4 August, but have dropped each day landing at 10 on 8 August and just 6 yesterday. Fingers crossed?

In the remaining states the picture is similar in that deaths are rising, but not nearly as badly as they are in Illinois. In Illinois the death rate tripled, but to be fair it also did so in Delaware. Though that meant climbing from 0.1 to 0.3. In the states where we are seeing deaths from Covid-19, the rates have not even doubled. Pennsylvania and New Jersey are the two closest to hitting that grim number. Their seven-day averages of 3.6 and 3.7, respectively, have reached only 6.6 and 6.4, respectively. Certainly not good, but perhaps we can be cautiously optimistic given the states’ relatively high rate of vaccination.

In Virginia we have seen the death rate climb from an average of 4.4 per day, nearly the same rate as Illinois, which has a lower overall rate of vaccination, to only 5.6 deaths per day as of yesterday.

It is important to note that vaccinations are doing a good job at keeping the vaccinated from needing to go to hospital or even dying. The phrase “pandemic of the unvaccinated” is very accurate. Whilst the vaccinated can become infected, most suffer very mild symptoms or are asymptomatic. The reason for masking is that the Delta variant can infect the vaccinated to such a degree that, whilst not sick, they can infect the unvaccinated.

If you have not been vaccinated yet, it is critical that you do so. They are safe. They are effective. And they are free. There are only a few valid reasons for not receiving the vaccination. And “not wanting it” or “not needing it” or “not trusting the government” or “not sure whence the virus came” are not valid excuses.

Covid Update: 5 August

Note: This was supposed to post Friday morning. But it didn’t for technical reasons. Throwing it up late because I’ll probably wait until Tuesday and the release of Monday data to do another update. And I want people to have the latest charts for the weekend.

Unfortunately, I don’t have a lot of time to write up my usual analysis of the charts. Maybe I’ll do that for Monday, we’ll see. But I do want to post the latest Covid-19 data on cases and deaths before we head into the weekend.

The overall picture is that things are continuing to get worse. You can see that in all states the fourth wave, driven largely by the Delta variant, is here.

New case curves for PA, NJ, DE, VA, & IL.

When we look at deaths, last week I had mentioned how deaths were still trending down. But as a lagging indicator it was just a matter of time before the new cases led to new hospitalisations led to new deaths. And that moment appears to have just arrived.

Death curves for PA, NJ, DE, VA, & IL.

I should point out that Delaware appears to have folded in their probable deaths in with their confirmed deaths, as many states had done months ago. So that spike of 135 new deaths isn’t “real” as in those deaths happened a long time ago. The pre-probable death number was the same as afterwards.

Covid Update: 28 July

Another week, more bad news when it comes to Covid-19 in the states of Pennsylvania, New Jersey, Delaware, Virginia, and Illinois. Last week I wrote about how the slight upticks in new cases in the states were not so slight. This week it’s more of the same, though it would be fair to say that the spread of Covid is beginning to accelerate, although in some states more quickly than others.

To start, the most basic of refreshers. Pennsylvania, New Jersey, and Delaware are all in the Northeast. Virginia is in the South. Illinois is in the Midwest. At a broad level, Covid is beginning to strike places with low vaccination rates and in particular has been hitting the South and Midwest fairly severely. You might say that Virginia has the northern suburbs of Washington and Illinois has Chicago, but in both states simply head south and west and you’ll very quickly find yourself in an entirely different culture, almost a different state in both. And it is in those parts of the states where the increase is most noticeable.

Conversely, the Northeast has had some of the highest rates of vaccination and the new Delta variant is taking longer to take root. Because, that’s the entire point of the vaccination process. We want to starve the virus of potential host bodies. But we needed to reach much higher than the 50-odd percent of the states to be fully vaccinated. So where are we? Let’s take a look.

New cases curves for PA, NJ, DE, VA, & IL.

The recent tails are curving up now and it’s plain to see. Two weeks ago the tails were barely noticeable in most states. You had to really look at the numbers to see the differences. Even last week in Pennsylvania and Delaware the tails were still fairly flat. This week is unmistakable. You may be over the pandemic and done with Covid, but the pandemic isn’t over and it’s not done with us.

In both Virginia and Illinois the seven-day averages for new cases rose by nearly 50% in the last week. Yesterday Illinois reported more than 2,000 new cases, the first single-day report that high since the beginning of May. And in Virginia we had more than 1,000 cases yesterday, again the most in a single day since the end of April.

In the tri-state area we also saw increases over the last week, albeit not as great as in Virginia and Illinois. Though they weren’t off the pace by much. In fact, at this rate, I would not be surprised if next week I write how both Pennsylvania and New Jersey see more than 1,000 cases in a single day. Neither state is there yet, as New Jersey reported 830 yesterday and Pennsylvania only 645—though it reported 986 on Tuesday. Both states’ seven-day averages are also a bit behind Virginia and Illinois, but again, I would not be surprised to see them nearing 1,000 though maybe not surpassing it this time next week.

I cannot overstate this next part, however. The virus is primarily infecting, sickening, and killing the unvaccinated amongst us. If you have not received your vaccine shots yet, please, please do. The vaccines have been proven safe. They have been proven effective. And they are free.

The good news, if we want to find some, is that the death rates largely continued to fall overall.

Death curves for PA, NJ, DE, VA, & IL.

Largely. Keep in mind as I noted above, the deaths are almost all occurring in those who have not been vaccinated. Now in Virginia we are seeing the death rate increase, though not yet dramatically. Last week the seven-day average was three per day. This week we are at four.

But compare that to three of the other four states. (Delaware continued to have almost deaths and its average is zero.) Last week both Pennsylvania and New Jersey had averages of 5 deaths per day and this week they area at 4. And in Illinois the average fell from 7 to 4.

What I will be watching over the next week or two is whether these death rates begin to increase beyond Virginia. I mentioned before how deaths are a lagging indicator and we are beginning to reach the point at which, during earlier waves, where we could begin to see increasing numbers of deaths.

But again, the key is for any and all my readers who are unvaccinated, please make an appointment to get your shots as soon as possible.

Olympic Recap/Retro

Every four years (or so) I have to confess that I think fondly back upon my former job, because I worked with a few wonderful colleagues of mine on some data about the Olympics. And the highlight was that we had a model to try and predict the number of medals won by the host country as we were curious about the idea of a host nation bump. In other words, do host countries witness an increase in their medal count relative to their performance in other Olympiads?

We concluded that host nations do see a slight bump in their total medal count and we then forecast that we expected Team GB (the team for Great Britain and Northern Ireland) to win a total of 65 medals. We reached 64 by the final day and it wasn’t until the women’s pentathlon when, in maybe the last event, Team GB won a silver medal bringing its total to 65, exactly in line with our forecast.

Probably the most Olympics I’ve ever watched.

Of course we also looked at the data for a number of other things, including if GDP per capita correlated to Olympic performance. We also looked at BMI and that did yield some interesting tidbits. But at the end of the day it was the medal forecast that thrilled me in the summer of 2012.

So yeah, today’s a shameless plug for some old work of mine. But I’m still proud of it two olympiads later.

If you’d like to see some of the pieces, I have them in my portfolio.
