General slip-and-fall doesn't seem like it would be highly gendered.

The amount of falls I'm guessing is fairly similar, but older women are a lot more likely to end up in the trauma ward from it. For one there are just more old women than old men in my area and they are far more likely to have osteoporosis.

Do you find pool injuries are overwhelmingly one sex?

I generally see a lot more young men and boys from injuries from the pool. More rough housing, diving, and running around on wet concrete.

My assumption would be that males would tend more towards risky behavior around a pool.

We just go to the local puddle during the rainy season, typically between January and December.
