    This article is written in honor of the Pidyon HaBen of Amita Yaakov, the author’s great-nephew.

    A Pidyon HaBen is a ceremony that is somewhat rare, and only occurs in 1 out of X births. It is difficult to estimate how common they are, but let’s give it a shot. What follows is an exercise in halacha, math, and medical statistics. We are solving for X, of course.

    According to the 2020 Pew Research Center study, Orthodox Jewish families have approximately 4.1 children each.  Since  a PH is done only for male children, so far, we have 1 out of 8.2 births.

    A PH is not done if the baby was born by C-section.  The rate of primary C sections in the US according to the CDC ( is about 20.6% so we divide 8.2 by .794 and we get 1 out of 10.33 births.

    The next factor, sadly, is the percentage of first births that come after a miscarriage.  Technically, in order for a baby to be exempt from a pidyon haben after a miscarriage the first baby that was lost had to fulfill two requirements – 1] it must have been more than 40 days into the pregnancy and 2] it must have had formed limbs.  [See Shulchan Aruch YD 305:22-23].  Practically, Rav Moshe Feinstein zt”l ruled that one may hold a Pidyon HaBen with a bracha if the miscarriage happened up until ten weeks of the pregnancy.  This author’s calculations are that approximately 6% of pregnancies miscarry after ten weeks.  So we divide our 10.33 by .94, and we get 1 in 11 average births.

    The final factor is whether the child’s father is a Kohain or Levi or if the mother was a daughter of a Kohain or a Levi.  Since the incidence of Kohanim and Leviim is about 4% each and we add these factors together, we would divide our 1 in 11 by .84 and we would get 1 in 13 births.  This figure is assuming 4.1 children per family.  The rule of thumb is that you take the average family size and multiply that by 3.2.

    I made a PH for my son. He made a PH for his son. And his son made a PH for his son.
    My daughter made a PH for her son.
    3 of my daughter’s children made PH for their sons.
    3 children of my other son made PH for their sons.

    This makes it a total of 10 Pidyan Habens in my immediate family.

    I wish such simchas for ALL of KLAL YISROEL….

    I had one, and I have the bencher to prove it. Fortunately, my parents chose to redeem me. Not sure they got the better of the deal. 🙂

    Under normal circumstances, Pidyon HaBen is not performed if the mother was a daughter of a Kohain.

    But, if a daughter of a Kohain is physically intimate with a non-Jew, then her first-born-son is no-longer-exempt from Pidyon HaBen.

    I actually knew a Baal Teshuvah who never got Pidyon HaBen because his mother was a daughter of a Kohain.

    I never told him that he is not exempt from Pidyon HaBen, because his father was not Jewish.

    I feared the he might accuse me of conflict-of-interest, because I am a kohain myself.

    Even more so, I also feared that he might go off-the-derech, if I told him that he is not exempt from Pidyon HaBen, because his father was not Jewish.
