Tree rings to compare life expectancy in your state

The Washington Post goes with a tree ring metaphor to compare life expectancy in your state. Enter your sex, age, and state. The inner white circles represent how old you are, the middle yellow circles represent how many expected years you have left, and the outer red circles represent the expected years of those with the same age and sex but in Japan.

The rings are a lead-in graphic to more statistical charts. I kind of wish they went all in with the rings, but that’d probably be limiting in the points they could get across.

Shifting causes of death over the decades

Saloni Dattani, for Our World in Data, used a set of heatmaps to show how causes of death changed by time (on the horizontal axis) and age (on the vertical axis) in France. Each panel represents a cause category.

The code is on GitHub, in case you want to make similar charts for your own country.

Increasing alcohol-related deaths

Alcohol consumption, based on ethanol volume estimates, has been rising over the past couple of decades. The pandemic appears to have sped that up, leading to more deaths. For The Washington Post, Caitlin Gilbert, David Ovalle and Hanna Zakharenko report:

At the same time, the number of deaths caused by alcohol skyrocketed nationwide, rising more than 45 percent. In 2021, alcohol was the primary cause of death for more than 54,000 Americans, causing nearly 17,000 more deaths than just a few years before, in 2018, according to data from the Centers for Disease Control and Prevention.

Full scope of gun deaths in the U.S.

As I’m sure you know, mass shootings, which gain attention because the scale of their severity is so high, make up only a fraction of total gun deaths. Several tens of thousands of people die from gun shots every year in the U.S. The Washington Post describes the full scope, covering purchases, restrictions, race, and geography.

Lives cut short by Covid

Alyssa Fowers and Leslie Shapiro, for The Washington Post, used the stories of 114 individuals to show weekly Covid deaths. Each story is “cut short”, making the length of each fragment match counts for the corresponding week.

My brain was slightly confused by the metaphor at first. The lower the count, the more an individual’s story is cut short, but my intuition expected that more deaths would mean stories were cut short more.

That said, the sentiment is in the right place. Maybe the stories didn’t need to be tied to weekly counts? I’m imagining something closer to Periscopic’s piece from 2013 on lives cut short by guns.

Behind the million

Sergio Peçanha and Yan Wu, for The Washington Post, used a combination unit chart with individual icons to represent the scale and weight of the near million Covid deaths in the United States.

Compare this with NYT’s particle-based charts and Axios’ scaled squares. It’s kind of in between the two in level of abstraction, but all three carry similar messages, with a focus on the one-million mark.

Reaching 1 million deaths

The New York Times narrated the path to one million Covid deaths in the United States. They start with one million dots, each one representing a death. As you read, the dots arrange into trends and significant events over these past years.

As we have talked about before, it’s impossible to communicate the true weight of a single death, much less a million, but the individual dots provide a visual foundation to better understand abstract trends.

Scale of one million deaths

The United States is about to reach one million confirmed Covid deaths, or already passed the mark if you consider excess deaths. There’s no way to truly feel that number, but Axios visualized the scale, with comparisons against city populations and historical events.

A diamond shape represents counts, and as you scroll, shapes fill the screen until you only see the tips. The shapes overflow beyond what we can or want to understand. The time series line on the bottom shows cumulative deaths over time, leading towards the one-million mark.

Increasing mortality baseline

There was a time not that long ago when a hundred covid deaths seemed like a lot, but now the United States is getting closer to one million deaths with over a thousand deaths per day. The country is unmasking and re-opening. For The Atlantic, Ed Yong discusses the shifting baseline and our perception of these big numbers:

The United States reported more deaths from COVID-19 last Friday than deaths from Hurricane Katrina, more on any two recent weekdays than deaths during the 9/11 terrorist attacks, more last month than deaths from flu in a bad season, and more in two years than deaths from HIV during the four decades of the AIDS epidemic. At least 953,000 Americans have died from COVID, and the true toll is likely even higher because many deaths went uncounted. COVID is now the third leading cause of death in the U.S., after only heart disease and cancer, which are both catchall terms for many distinct diseases. The sheer scale of the tragedy strains the moral imagination. On May 24, 2020, as the United States passed 100,000 recorded deaths, The New York Times filled its front page with the names of the dead, describing their loss as “incalculable.” Now the nation hurtles toward a milestone of 1 million. What is 10 times incalculable?

Death rates by vaccination booster status

Our World in Data continues their important work on providing and showing up-to-date Covid data. Most recently, they updated death rates in Switzerland by vaccination plus booster status. The rates for the unvaccinated are expectedly much higher, but also the rates for those with a booster are multiples lower than those fully vaccinated with no booster.
