<p>If there's any relationship, I think it would be the reverse of what you said. Since kids born in the early months tend to better academically because of developmental advantages, their younger peers have to work harder to keep up. When the several month age difference becomes negligible, they find themselves ahead while their older classmates, used to being ahead of the game effortlessly, fall behind.</p>
<p>I actually be really interested to see hard numbers on something like this, because there are decent arguments on both sides. Either way, statistics can obviously oversimplify an issue. There will always be really smart younger members of a class and really smart older members of a class. All statistics can do is make a generalized statement.</p>
<p>Most people, regardless of academic prowess, are born in the early months of the year (February-May), and this is because it's much more fun gettin' it on in the summer when you can go outside and don't have the the burdens of school and sometimes work. 9 months + April-August = February-May.</p>
<p>I would argue the reverse because when it's cold outside, people stay indoors more, you can snuggle for warmth, and there's one boredom-busting/heat-generating activity you can almost always do with a partner... Plus, what better way to celebrate the New Year/Valentine's Day? Therefore: more babies born in August-December.</p>
<p>nah - i've read/heard that more babies are born in late winter/spring than in the rest of the year. besides that, it seems that way from personal experience. my mom's birthday is january (well, today, actually), mine's february, i have another 3 friends with feb. birthdays, and another 3 or 4 with birthdays in the spring also. I can only name about 3 friends/family with winter/summer birthdays.</p>
<p>^ is that the stats just for the US or for the entire Northern hemisphere? (if it was the same for the entire world then that kinda debunks the theory about ppl getting it on in the summer since Southern hemisphere summer is our winter)</p>
