Some interesting stats from Pew Research Center. I’ve just included some highlights which I’m directly quoting from their website and have included the links so you can look at the stats more in depth if you want.
Number of People Never Married on the Rise

“Since the first Religious Landscape Study was conducted in 2007, the share of Americans who are married has continued to decline, while the share of adults who have never been married has risen sharply. In fact, recent analysis of census data shows that the share of Americans who have never been married now stands at an all-time high.”
Interfaith Relationships
“Interfaith relationships are common among married people and those living with a romantic partner, and interfaith marriage appears to be on the rise.”
“Interfaith relationships are far more common among unmarried people who are living with a partner (49% of whom have a partner with a religion different from their own) than among married people (31% of whom are in a religiously mixed marriage). Even among married people, however, mixed-faith relationships appear to be growing more common. Nearly four-in-ten married people who were wed since 2010 have a spouse who identifies with a different religious group.
These patterns strongly suggest that intermarriage has been rising, but it also should be noted that some research indicates that “in-marriages” (marriages between people of the same religion) tend to be more durable than intermarriages.”
More Women Identify with Christianity than Men
http://www.pewforum.org/2015/05/12/chapter-4-the-shifting-religious-identity-of-demographic-groups/
“Women are far more likely than men to identify with Christian groups (75% vs. 66%). Men, by contrast, are more likely than women to describe themselves as religious “nones” (27% vs. 19%).
But both men and women have become less Christian and more unaffiliated since 2007, by roughly equal amounts. The share of men who identify with Christianity has shrunk by eight percentage points since 2007, and the share of self-identified Christians among women has declined by seven points. Meanwhile, the share of “nones” is up seven points among men and six points among women.”
