His analysis is drawn from mountains of statistical research combined with a keen understanding of how both families and congregations actually work. The best predictor of church attendance for young adults is marriage. Wilcox cites Princeton sociologist Robert Wuthnow's report that decreases in marriage and childbearing among young adults were "by far the strongest predictors" of a decline in religious attendance. As a matter of fact, Wuthnow argues that American churches would now have 6.3 million more young adults attending if marriage and childbearing rates had not fallen so precipitously.
Wilcox suggests what observers of young men already know -- "the link between religious attendance and family life is particularly strong for men." As Wilcox explains:
Currently, men are 57 percent less likely to attend church regularly if they are not married with children, compared to men who are married with children. Women are 41 percent less likely to attend church regularly if they are single and childless. Marriage does more than bind a man to one woman; it also ties a man to a local congregation.

For men, marriage, fatherhood, and churchgoing are a package deal. Men's comparatively fragile faith often depends on wifely encouragement to flower. More important, fatherhood often awakens in men a sense of paternal responsibility that extends to their children's religious and moral welfare. Men are much less likely to identify with and be able to fulfill the responsibilities of fatherhood--including the religious ones--if they are not married to the mother of their children. This is why divorce is much more likely to drive men away from church than it is women.
This makes a great deal of sense and a look at congregational life will tell the story. Marginalize marriage, depreciate childbearing and fatherhood, and say goodbye to young adult men in church.
In a fascinating analysis, Wilcox suggests that evangelical congregations have done relatively well in attendance and draw considerable numbers of young adult men precisely because those congregations tend to support, honor, and encourage the establishment and health of intact families.
Liberal Protestantism, on the other hand, has swallowed something of a poison pill. They have embraced trends weakening the family and have encouraged "alternative lifestyles" -- trends that have been disastrous for their own attendance.
