For sample persons under 6 years old whose respondent is their biological mother and whose mother had previous miscarriage, PGMISCARYTIM reports the length of time between the person's birth and her/his biological mother's most recent miscarriage. If the person's biological mother did not report ever having a miscarriage, they are recorded as "no known miscarriage."
