I use an intergenerational data set that is uniquely suited to estimat
ing the magnitude of religiosity inheritance. Interviews with 471 pare
nts in 1980 and their adult offspring in 1992 address three related is
sues: (1) What are the effects of childhood, parental, and family infl
uences on the religiosity of adult offspring? (2) What factors conditi
on the ability of parents to transmit their religiosity? (3) How do th
e recent experiences of adult offspring modify earlier family influenc
es on religiosity? The results suggest that three sets of variables ai
d the transmission of religiosity-parental religiosity, quality of the
family relationship, and traditional family structure. One's religios
ity is determined largely by the religiosity of one's parents. Parent'
s marital happiness, parent-child support, moderate strictness, and a
working husband/nonworking wife increase the ability of parents to tra
nsmit their religious beliefs and practices. Although the recent exper
iences of adult offspring affect their religiosity, these experiences
do not reduce the influence of parents and family context.
