Not noted is how many of each group are in the top 3-5 percentile bracket, which is where all the physicists, engineers, mathematicians and technologists live. The usual ratio is at least 3-to-1 in favor of males.
The ratio of girls to boys in my son’s national honor society organization is 2 to 1. Just a spot sampling and our last meeting.
My son’s school is your typical public High School.
