Affiliation with the Catholic faith delays marriage (t = –3.4); the probability of having entered first marriage by age 20 is only 0.05 for Catholics, compared to 0.09 for mainline Protestants. The point estimate for a Jewish upbringing yields an even more pronounced effect: a probability of marriage by age 20 of only 0.02. However, the number of Jews in the sample is small (n = 22), and the coefficient attains significance only at the 15% level. In contrast, two groups display a pattern of very early entry into first marriage: conservative Protestants (t = 4.3) and Mormons (t = 2.5); the probability of marriage by age 20 is fully 0.17 for members of these groups, almost twice the value for the reference category.
