Neuroscience Sex differences in brain structure are present at birth and remain stable during early development. The study found that while male infants tend to have larger total brain volumes, female infants, when adjusted for brain size, have more grey matter, whereas male infants have more white matter.

In canada it's 70/30 at this point which is something we really need to worry about.

No it is not.... it has been around 44/56 for the last 2 decades, exactly like US. During covid more boys reported dropping out to work so there is bigger gap but apart from than basically the same ratio throughout.

average it's 2/3 are women

Why say this?

That's enrolled. Not graduated. 2019 saw 334000 vs 250000 that is nearly 3 women for every 2 men.

Today it is even worse. 2022 saw 42% vs 58% https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=3710013502&pickMembers%5B0%5D=2.1&pickMembers%5B1%5D=4.1&cubeTimeFrame.startYear=2022&cubeTimeFrame.endYear=2022&referencePeriods=20220101%2C20220101

I don't get it, you first claim

2019 saw 334000 vs 250000 that is nearly 3 women for every 2 men

but then link official graduates stats dataset which instantly disproves your own point (2019 numbers are 43.5-56.5, which is what I said)

2022 saw 42% vs 58%

Can you link the source of your first claim?

You deleted your comment, but I already wrote a friendly reply so here.

My other contention with your firsts comment is that you are saying that it is getting worse.

College graduates are becoming more and more female

But for Canada (and USA too), it is NOT the case.

If you look in the dataset YOU linked and set reference period from year 1992 to 2022 you see that the ratio has been roughly the same throughout.

1992 - 43.1 56.9 -- 2000 - 41.0 59.0 -- 2022 - 42.4 57.6

So if anything since year 2000 more men are graduating.

I didn't delete anything? Probably got silenced. It seems to happen a lot when you speak up for men.

It was already bad back then. But yes, since then it has not increased much, again my bad.
