Does it seem like you have been attending a lot of birthday parties recently? Could there really be more births in some months than in others?

According to the National Center for Health Statistics, the birth rate in the United States reaches its height during the months of July, August, and September. And, it isn’t just because these three months have the most days; the rate remains even after adjusting for this. Couples are simply more likely to get busy during the months of October through January, when these babies are conceived, than during the other months. It is speculated that the cold weather leads to more stayin’ in and more lovin;’ although, you probably already figured that out.

And, it’s not just cold weather that leads to new babies, very hot weather in seasonal climates also seems to be related to births nine months later. What have you been doing this summer? The lowest birth rates occur from November through March, so apparently, "spring fever" doesn’t apply to making babies.

When is your birthday? Does the month in which you were born really mean anything? Well, you might be surprised. Here’s a list of things that have been studied or actually found to be related to the month or season of one’s birth: temperament, maturation rate, lifespan, neurological disorders, narcolepsy, epilepsy, multiple sclerosis, schizophrenia, brain cancer, and rates of diabetes in children.
