The effects of religiosity on reproductive timing were somewhat mixed, with findings difficult to interpret. Religious affiliation was associated with earlier first childbirth for women and men in the older cohort. However, weekly church attendance was associated with delayed reproduction, although for neither women nor men was the association significant. For women in the young cohort, religious affiliation was also associated with earlier childbearing after age 24, but delayed childbearing before age 24. For men, a slight, but nonsignificant delay was observed. In the young cohort, weekly church attendance was associated with earlier first childbirth for both women and men. Not surprisingly, never marrying was strongly predictive of delayed childbearing for men and women in both cohorts.
