Communicating effectiveness of boosters

Statisticians David Spiegelhalter and Anthony Masters for The Guardian on reframing risk estimates: An earlier UKHSA study estimated two Pfizer/BioNTech doses gave around 99.7% (97.6% to near-100%) protection against Delta-infected hospitalisation, but after 20 weeks that effectiveness waned to 92.7% (90.3% to 94.6%). This estimated decline for people over 16 may not sound much, but if we look at it in terms of “lack of protection”, their estimated vulnerability relative...

Visual guide to redistricting

Gerrymandering continues to be an important thread that I think many people still don’t understand, mostly because it’s called gerrymandering. The Guardian provides a visual guide to explain how creative redistricting can lead to favorable votes. If you’re still not sure, see also the game District by Christopher Walker which walks you through what gerrymandering is and how it works. Tags: gerrymandering, Guardian, redistricting

Measuring centuries-old droughts through tree rings

To measure drought in the present day, we use data from sensors that constantly record environmental conditions, such as soil moisture, precipitation, and snow water content. But to measure drought thousands of years ago, researchers can use tree rings. Alvin Chang for The Guardian shows how the researchers line up old rings to gather historical data and then do that across a region. Tags: Alvin Chang, drought, Guardian, tree ring

Melting glaciers

Niko Kommenda for The Guardian used small multiples to show 90 of the largest glaciers in the world and how they have melted over many decades. The animation transitions between two time periods for each glacier, showing what was there earlier and what is left. Tags: climate change, glaciers, Guardian, Niko Kommenda

Visual guide for the fires in Australia

For The Guardian, Niko Kommenda and Josh Holder provide a visual guide to the bushfires in Australia: Satellite data from Nasa showed a stark increase in the number of fire detections in November and December compared with previous years. Satellites detect fire “hotspots” by measuring the infrared radiation emitted by the blazes. In previous years, between 2,000 and 3,000 such hotspots were recorded each December in the south-east, while in...

Getting to zero coal in Britain

For The Guardian, Niko Kommenda shows the decrease in coal usage for power since 2012. As of this writing, it’s been just under 11 straight days with 0% of power generated by burning coal. The data comes from Gridwatch, which in turn scrapes reports using the Balancing Mechanism Reporting Service from Elexon. Is there a US equivalent? Tags: coal, energy, Guardian

Midterm shifts versus the 2016 election

The Guardian goes with scaled, angled arrows to show the Republican and Democrat swings in these midterms for the House compared against those of 2016. It reminds me of the classic wind-like map by The New York Times from 2012, but the angles seem to give the differences a bit more room to breathe. Tags: difference, election, Guardian

Endangered species that could fit in a train car

There are endangered species where the remaining few in the world could fit on a single car train. Mona Chalabi for The Guardian imagined such a scenario. Usually when we talk about scale and putting numbers into perspective, it’s about imagining the large ones. What does a million look like? A billion? Chalabi’s illustrations take it the other direction. Tags: animals, endangered, Guardian, scale

Day of the year companies stop paying women

One way to think about gender pay gap is to imagine women receive the same pay as men each working day until they reach their salary. At some point during the year, women effectively work for free. With a new law that requires companies in Great Britain with 250 or more employees to report pay gap, The Guardian provides a calendar view into the newly reported data that shows the...

Facebook logs calls and text messages

Woo. Woo. Alex Hern reporting for The Guardian: In at least one previous version of the Messenger app, Facebook only told users that the setting would enable them to “send and receive SMS in Messenger”, and presented the option to users without an obvious way to opt out: the prompt offered a big blue button reading “OK”, and a much smaller grey link to “settings”. Nowhere in the opt-in dialogue...
