In case anyone is curious

> In 2016 in the US, adult women averaged a weight of 170.3 lb. The median adult woman weighed 161.3 lb.

> For men in the United States 18 or older in 2016, average weight was 197.1 lb. Men had a median weight of 189.4 lb.

I guess it makes sense that even the median weight would lead to an overweight BMI (assuming average height), since 74% of the US is overweight or obese.
