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

With this straightforward unit chart, wcd.fyi 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.

Redefining Old Age

What is old? When it comes to subjects like health care and retirement, we often think of old in fixed terms. But as people live longer, it's worth changing the definition. Read More

Finding the New Age, for Your Age

You've probably heard the lines about how "40 is the new 30" or "30 is the new 20." What is this based on? I tried to solve the problem using life expectancy data. Read More

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.
