How teenagers’ job ambitions have changed

The Programme for International Student Assessment (PISA), run by the OECD since 2000, surveys teenage students to estimate the quality of education around the world. One of the questions asked: “What kind of job do you expect to have when you are about 30 years old?” For Vox, Alvin Chang walks through how the responses changed over the past two decades, which appears to suggest that students are less certain about what the future holds.

There are some tricky spots in explaining misalignment between ambition and preparation, but Chang does a good job of moving along step-by-step.

Why South Koreans grew taller so quickly

As a world population, we’re growing taller, but South Koreans seemed to grow a lot quicker over the past century. Vox breaks down height distributions and explains the increased rate in South Korea in their Vox-y combination of paper, slides, and digital. Wealth and improved food supply appears to have helped things along.

There’s one part when the narrator Alvin Chang says he has to adjust the vertical axis to see the change in height better. My chest might have tightened as my mind went to bar-charts-start-at-zero land, but the bar chart in the video switches from height to change in height, so it was all okay. Phew.

Inflation explained with eggs

The prices of everything seem to be rising a lot lately. Why? For Vox, Emily Stewart uses eggs as a case study to explain:

“There are different ways of thinking about the inflation issue, and economists by default tend to think about macroeconomic issues such as inflation in macroeconomic terms,” said Isabella Weber, an economist at UMass Amherst. “In this current situation that we are facing, we basically have very strong micro dynamics, that is dynamics on the level of specific sectors that translate into a more general kind of price pressure.”

Eggs don’t paint the full inflation picture in the US, but they do a part of it — it’s more expensive to feed chickens and move eggs around, so it’s more expensive to produce and move eggs, so it’s more expensive for consumers to buy eggs.

Stat-driven view on how American conservatives shifted against vaccine

As we know by now, conservatives in the U.S. are more commonly against getting vaccinated for Covid, but it wasn’t always like that. Vox shows how ideas shifted to get to where we are now.

The 1990s elementary school aesthetic with markers and overhead projector slides works well here. The choices guide you step-by-step through the data points.

How the 3-point line changed basketball

Vox shows how the 3-point line is “breaking” the game.

The basic math says a 3-point shot is more efficient for scoring points than a 2-point shot if the team can make a high enough percentage of attempts. It’s why the mid-range shot has fallen out of favor.

But it’s more an evolution than a breaking. Defense adapts, and then offense adjusts to that, etc. Stephen Curry making double-digit threes is still way more exciting than Curry not making threes.

How online school ratings are flawed

Standardized ratings are a challenge, because they often try to encapsulate many variables into a single variable. On the upside, a single score is quick and easy to see, but on the downside, variance goes into hiding and people/things that don’t fit a defined standard get dinged.

Vox looks at these challenges in the context of online school ratings.
