There are a number of interesting points to this graph.
* People tend not to be born on certain holidays, especially Christmas. This is probably due to the scheduling of induced births. * Only a quarter of the normal number of people are born on leap day, because it happens only once every four years. * The highest point of the year is just about 9 months after New Year's Eve. Wonder how that happens, lol.
Somewhere I read, but can't remember where, that people born in the warm months are longer lived than those born in the coldest months. Don't know what would account for that either.
There was another interesting graph showing that people in northern climates are more likely to be born in the spring, and that as you go south, the most frequent birth month consistently shifts to later in the year, to a maximum in September for the tropics.
All the dips in the graph are due to the propensity of the medical profession to artificially induce birth on days that are convenient for themselves and the hospital rather than natural for the mother. Sometimes the mother's wishes may also play a role, I think Feb 29 is a day that they all wish to avoid, and maybe also the other holidays. The father? Nobody cares what the father wishes. Her body, her choice is the mantra.
