One statistic that I do remember reading about a few years ago is that less people of both genders are getting married and staying married for more than a few years. I think the article said something about 23% less people below age 30 are getting married in the 2000s and 2010s than they were in the 80s and 90s.

I will check out those sources that were posted later today but I have to leave shortly and I don't use PC on my smartphone due to privacy concerns.
