There was a poll about firstborns.
That poll shows a remarkable result, the number of people that are the oldest sibling outnumber those who have older siblings 2:1.
There are also twice as many only children in that survey as in the U.S. population in 1980, but that is a known effect.
More than 3:1 even. I speculated a bit here.
