I’d like to know if there is any connection between birth order and choice of occupation later in life. I’ve read that most U.S. presidents were firstborns, but this might not be that surprising when you consider that almost all of them were WASP’s who tend to come from smaller families. Are there any studies that have shown that members of a particular profession are disproportionately firstborns (or lastborns)?
I was hoping for something factual, like “70% of physicians are firstborns, whereas only 30% of the general population are firstborns.” I realize that even if such a link were to be established, we still wouldn’t know if it was because firstborns are more “goal-oriented” or if it was due to parental favoritism toward firstborns in allocating time/resources. But it would at least be a start.
