While the relationship between religion and marriage and family is widely documented in sociological literature, limited research examines how a person's religiousness is related to the age at which she or he marries. The studies that look at this topic document a relationship between identifying as an adherent to certain religious traditions and marrying earlier than those who are not religious. However, these studies only state that a relationship exists and do not attempt to explain this correlation. Using data from the National Study of Youth and Religion (NSYR), various religious and demographic factors are used to examine how religious emerging adults differ from their non-religious peers on the measure of ideal age of marriage. I find that young emerging adults' ideal age of marriage is correlated with identifying as religious, although this relationship can mostly be explained statistically by attitudinal and demographic variables. Stating that faith is important to one's daily life, being female, supporting the male breadwinner model in marriage, and remaining sexually abstinent before marriage also help explain some of the relationship between religious tradition and ideal age of marriage. However, identifying as mainline Protestant or Mormon are significantly related to a younger ideal age of marriage, even after controlling for multiple other factors.
