Here is an interesting article from Touchstone by the author Frederica mentions. His numbers come from George Barna surveys.http://touchstonemag.com/archives/article.php?id=14-01-026-f
Missing Fathers of the Church
The Feminization of the Church & the Need for Christian Fatherhood
by Leon J. Podles
You may have noticed that, in general, men are not as interested in religion as women are. There are usually more women than men at Sunday mass, and there are far more women than men at devotions, retreats, and prayer groups. The men who do come are often there because wives or girlfriends have put pressure on them to attend. In fact, if men speak honestly, they will tell you that men have a general feeling that the Church is for women. They may add that women are more emotional than men are, or that religion is a crutch that a man doesn’t need, as Jesse Ventura, the candidate of young white men, said in Playboy.
[further on he writes:]
Nor do women simply join churches more than men do. They also are more active and loyal. Of Americans in the mid-1990s, George Barna writes that “women are twice as likely to attend a church service during any given week. Women are also 50 percent more likely than men to say they are ‘religious’ and to state that they are ‘absolutely committed’ to the Christian faith.”4 The differences seem to be increasing rapidly. In 1992, 43 percent of men attended church; in 1996, only 28 percent.5 Patrick Arnold, a Jesuit of liberal theological leanings, claims that at churches he has visited, “it is not at all unusual to find a female-to-male ratio of 2:1 or 3:1. I have seen ratios in parish churches as high as 7:1.” Women are more active in all activities of the church, both in public and social activities, such as peace and justice committees, and in spiritual activities, such as prayer and Bible study.
Church attendance in the United States is about 60 percent female and 40 percent male. The more liberal the denomination, the higher the percentage of females. Fundamentalists are almost evenly divided, but the only religions that sometimes show a majority of men are Eastern Orthodoxy, Orthodox Judaism, Islam, and Eastern religions such as Buddhism. Men say they believe in God as much as women do, but the more Christian a practice or belief becomes, the fewer men will own up to it. Men go to church less than women do, they pray far less than women do, and they believe in the afterlife and heaven and hell far less than women do.
