It's not always a choice, even for a parent. I live 30 miles away from a city of 20-30K people. they have one hospital, and there's another 30 miles away, in the town I live in. The hospital in the larger city, however, is a Catholic hospital, which means that they won't do abortions, they won't do vasectomies, and most importantly to this discussion, any baby born there is circumcised without asking the parents. The small hospital in the town I live in is not, so many people will come from the larger city to have their kids born here, or get vasectomies, etc.
