Interesting... I heard something similar about Schizophrenia except their births are clustered more around Spring and early Summer.
I was born in mid September, as were 4 others of my 8 sibs. This tells me my parents liked to have New Year's Eve sex. Eeeew.
I would think to do a proper study, you would need to see if the months of conception were actually cold that year. Is it the weather or the alignment of the planets?
I have a hypothesis that there are times when people tend to have less sex, and when they finally do, they impregenate with old sperm. The male should have several ejaculations prior to impregnation to ensure fresh sperm. I was born in late February, putting me conceived in late May. But I am an Irish twin, conceived two months after my older brother's birth. This seems to fit. I think the problem may be strongly correlated to cold months but may not have a direct causal relationship. I have a similar theory about why astrology holds to the degree it does. It has nothing to do with the stars themselves, but the consistent correlation of months and constellations.
