There are lots of sources for data on Covid-19. Many of them just take data from government or hospital sources, and let you compare them however you want to. Others are a little more careful. Financial Times data journalists outline some of the problems:

Comparing the spread of coronavirus in different countries is difficult using the data being released by governments. Confirmed case counts depend heavily on the extent of countries’ very different testing regimes, so higher totals may simply reflect more testing.
Deaths are somewhat more reliable, but remain problematic because countries have different rules for what deaths to include in their official numbers.
It is important for us to appreciate the challenges facing education around the world, particularly in developing countries. Following a recent post by Monday Osagie Adenomon, “Data speak louder than words” (22 June 2021), I decided to add to the conversation, by reflecting on my experiences as an educator in another African country.

On August 2, 2021, the US government announced it had met its goal of 70% vaccinated. But what does that mean? 70% of what? And what does vaccinated mean? Well, they meant that 70% of US adults has received at least one dose of vaccine. That actually means 59% of the population in the United States has received at least one shot (and thereby are fairly well protected against the COVID-19 disease with the possible exception of the delta variant). It corresponds to 69% of those 12 and over (who are eligible for the vaccine in the US). But in terms of the entire population, those fully vaccinated (with one or two doses, depending on the vaccine used) make up 50%. The risk of catching the disease for vaccinated people is relatively low, but much higher for unvaccinated individuals.

More exposure means more opportunities to mutate. More selection pressure means more variants. This is certainly true for COVID-19 and it might also be true for political rhetoric. The many additional news conferences, press briefings and talk radio slots brought on by the pandemic are perfect conditions for breeding new sound bites and rhetorical tricks. Angry journalists and members of the public provide the selection pressure, weeding out the phrases that fall flat.

Early in the pandemic, people started speculating about potential effects on birth rates. I started talking about news and research that asked the question, “Will coronavirus cause a baby boom, or is that just a myth?” At the time, I ended with a not-so-satisfying “we’ll know in about 9 months.”

It’s a cliché at this point for news articles to compare COVID spread to a wildfire. But the start of meteorological summer in the northern hemisphere this past week coincides with the start of the north American wildfire season, and COVID still rages across the planet, so bear with me a moment for another take on this metaphor.

When we think about massive migrations and humanitarian crises in the last five to ten years, we probably first picture the migrant waves caused by the conflict in Syria that started in 2011. After 10 years of civil war, 6.6 million people have been forced out of that country, and, according to the UN Refugee Agency (UNHCR), 6.7 million more remain internally displaced. More than 90% of Syrian migrants have found refuge in the neighboring countries of Egypt, Turkey, Lebanon, Jordan, and Iraq. Migrants also flee to European countries like Greece, Germany, and Sweden. This unfortunate and sad episode of human suffering might eclipse the second largest migratory movement and humanitarian crisis of recent years: the Venezuelan diaspora.

To open or not to open? that is the question:
Whether ’tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles
And by opposing end them.William Shakespeare, Hamlet
Did Hamlet wish for better data?

As the United States makes progress towards a state of “normality,” the country has set an incredible pace for vaccine production and distribution. But what information is lost in the big picture?
