Age generations in the U.S. Senate, over time

With this straightforward unit chart, shows which generation each Senate member belonged to, from 1947 through 2021. Each rectangle represents a senator, and each column represents a cohort.

As time moves on, the generations inevitably shift. In 2021, we have the first Millennial senator in Jon Ossoff from Georgia.

This Age is the New Age

30 is the new 20. Wait. 40 is the new 20. No, scratch that. 50 is the new 20. Or is 50 the new 30? Here’s what the Google says, so you know it must be true.

Grandpa Chad distribution

xkcd crossed a rough age distribution of people becoming grandparents with people named “Chad” and “Jason” to highlight the dawn of a new era. The time is now.

Timelines to make you feel old

One of the best ways to feel old is to look to your past and realize how long ago it was. Wait Buy Why demonstrates with a bunch of timeline splits. For example: “Remember when Jurassic Park, The Lion King, and Forrest Gump came out in theaters? Closer to the moon landing than today.

I feel like there was an xkcd comic about this, but the closest I could find in my notes was a tweet from Neil deGrasse Tyson: “Just an FYI: The year 1980 is as far in today’s past as 1947 was to 1980.”

Update: From xkcd, there was one on Movie Ages and another on Timeghost. (Thanks, @ilarischeinin and @CultureOverTime.)

Yay. We’re all old. Eventually.

Pitch speed distribution, a decrease with age

Pitch speed starts to decrease with a baseball player’s age at some point. This makes sense. That’s why athletes retire. The Statcast pitch distributions show when this happens for individual players, categorized by pitch type. I like the transparent distributions for past seasons as a mode of comparison.

Ages in Congress, from the 1st to the 115th

As I watched Google’s CEO Sundar Pichai field questions from the House Judiciary Committee it was hard not to feel like there was a big gap in how the internet works and how members of Congress think it works. Many suggested the gap was related to age, so I couldn’t help but wonder how the age distribution has changed over the years.

You can see the median age shifting older, but I’m not totally sure what to make of it. After all, the population as a whole is getting older too. On the other hand, the internet changed a lot of things in our lives, and the hope is that those forming the policies understand the ins and outs.

Heatmap shows deaths by age in different countries

This interactive heatmap by Jonas Schöley shows mortality rates by age. Just use the dropdown menu to see the data for various countries. You can also compare male and female populations and countries.

As you might expect, you can see mortality rates decrease steadily, especially in the younger ages. Spikes or abrupt color changes might indicate war or disease. [via @maartenzam]

Why time flies when you’re older

Why time flies

When you're a kid, a year seems like forever. Appending "and a half" to an age seems significant and necessary. But as you get older, the years seem shorter. Heck, I can't even remember how old I am half the time. Maximilian Kiener uses an interactive timeline to argue why this is. The more years you're alive, the lower the percentage a year actually is of your life. And eventually, one year is just a tiny sliver.

Turning 30, explained with charts

Turning 30

You get older as time passes. (That's how age works last time I checked.) You change, the people around you change, and you care more about different things and less about others. Cecilia Rabess describes the difference a decade makes in a series of humorous charts.

It's funny because it's true.

Excuse me while I get an IcyHot pack for my lower back and schedule an eye appointment. And why do they have to play that music so darned loud? [via @albertocairo]
