About how many pidyon haben ceremonies are required to be performed per 1000 Jewish births in the past few decades?
The requirements for a pidyon haben are:
- Both parents are Israel, not Kohen or Levi.
- Son is firstborn of the mother.
- No miscarraiges (after day 40 or 39) or stillbirths before the son.
- Vaginal birth.
One way to approximate this figure would be to multiply those statistics:
(PIsrael)2 * Pmale * (1−Pearlier miscarraige or stillbirth) * Pvaginal birth
Or, perhaps a better formula...
(PIsrael)2 * Pfirstborn is a male live birth * Pvaginal birth
Anyone have numbers on these?
