<p>Clearly individual boys and girls will not fit into the generalities. But as a rule, the girls do not tend to do as well in the math type subjects, and the boys tend to dislike writing. Boys tend to mature more slowly than girls. Boys tend to be more physical. Boys tend to have more learning disabilities and issues.</p>
<p>Again, all generalities. There are girls who excell in math and go into engineering. Some boys love to write (my youngest falls into this category) and dislike sports and rough housing. When they hit adulthood, some of these differences iron out. </p>
<p>However, young men are a group of high risk. They have more car accidents, get thrown into jail more, drop out of school more, die more. They are outnumbered by the girls at colleges these days. These are all realities, not opinions. Perhaps it is because they do mature more slowly, and those testosterone surges are not always matched with gray cell growth. I don’t know whether a single sex environment cuts down on their risks or increases them (I think about gangs–they are all boy). It’s hard to say, because the few single sex schools around are private, usually Catholic. So they do not represent the general population. There a handful of inner city public schools that have and are considering going single sex, but not enough and not long enough to come to a definite conclusion that having boys in a single sex school is overall beneficial. The same with girls. It is clear that there are kids who benefit, and those that are happier and do well in a coed environment. My guess is there are many that would do the same in either, or would have pros and cons that would balance each other out.</p>
