Yep... I loved that chapter. If the sports leagues are really interested in finding the best players regardless of birthdates, they could do a sliding cutoff that changes 3-6 months every year.

That way the "January" kids would sometimes be the oldest in their group, and would sometimes be the youngest. Depending on how they did it, a kid might either spend two seasons in one age group, or skip an age group altogether.

Divide the data by hemisphere. It would be really interesting.

As a economist, was going to say that. This is partly inconclusive data. It’s need to be crossed like you said with average births per month maybe across healthy males between 8-18 years of age and 18-35, to differentiate if this affects only in youth or in adulthood as well

It would be easy to enough to adjust for birth year. Instead of just birth month, it would be number of months older than the minimum.

For instance, someone who turns 17 on Sep 1 of their senior year (12th grade) would be considered "0 months" old. The typical range would be 0-12 months if everyone was born in that year, but someone who was held back and turned 18 two months before their senior year started would be "14 months". Your range might be as much as 0-24 instead of 0-12.

I’m very sad you think this way. I always try to be factual with my vizzes and while sometimes I have some hidden jokes or gimmicks on my vizzes this time I was very aware that there is of course no place for such thing so it is a very plain representation of the data which I do not own. I have all the sympathy for the victims and I deeply condemn any violence. That’s all I can say

So? I assume you've adjusted the Y axis to try and show a correlation, but I honestly can't think of any reason why central bank balance sheets (assets?) would be correlated with movements in Bitcoin's (exchange rate?). The movement of Bitcoin is so much more volatile it doesn't fit within the graph. I would try plotting changes in an aggregate of stock indices against changes in Bitcoin. Regulatory thinking is that crypto should be considered a security, so that might be interesting.

Sooooo completely unrelated?

Compared to “outside the US.”

It’s not the cheapest, but considering the US’ large size I’d say middle of the pack is pretty good.

Was just going to say this!

Malcom gladwell did an update on his podcast and observed that many parents are using his data as a reason to hold their children back a year to give than an academic advantage.

Idk if any relationship between pretend money and real money is statistically significant but the "conventional wisdom" would be an inverse correlation.

He’s done an update on his podcast recently. Now some parents are using his data to intentionally hold their Children back a year to give them an academic advantage. Enough to start skewing the data.

Edit - I don’t think gladwell came up with this idea but he did make it more mainstream.

This is why I have a big problem. Gun control people love to say "School shooting" but then they use this incredibly loose term and mental gymnastics to scare parents to voting away gun rights.

Even Vox, who's far left and supports gun bans, called them out.

Nope. I can fly around the EU for almost nothing compared to a flight from New Orleans to Atlanta.

You can't really tell because you don't know what data is the driver. They've agglomerated the balance sheets of five central banks in to one and you don't know what the percentages mean or what's driving them, neither do you know what's driving the bitcoin price, which could be completely different.

Nice relationship! Is this statistically significant?

Malcolm Gladwell wrote about this phenomenon in his book "Outliers"... great read.

This just backs up what I've been saying for YEARS about children's sports.

It has NOTHING to do with talent, and EVERYTHING to do with maturity.

Your kid isn't "good" at sports, they're just bigger than most people they're playing against.

If you mature early (like I did), you will likely be "good" at sports. (I was 5'10" in 8th grade.) You will be pushed to do sports more than someone who matures later, so, by the time that talent DOES come into play, you have many many more hours of training than someone who didn't start playing until a few years later.

It's relatively rare that someone matures late or is small and their talent alone carries them to the furthest levels of sports. (Think of people who were the "wrong" size for their sport. Generally someone who is very small in most american sports.)

9 months before September is December, most people take a lot of December off because of the holidays. It's also the end of the year when people reflect on their lives and what they may want to do next so I think it makes sense that a lot of people try for a baby around this time of year.

Need to normalize by total number of people born in each month, I assume it’s not uniform

Yeah, it's so metal!

But, instead of a circle, maybe each dot could be a child with some blood coming out?

Compared to where?
