The Heritage Foundation has a new website (at least it's news to me) called Family Facts. This website is a great resource for all sorts of findings related to marriage, family, children's issues, religion and faith.
Worth checking out are their top ten lists. This month's list, answering the question, "What Influences the Quality and Stability of Marriage?" is particularly good. You can find it on the front page.
Also, check out the video they produced on the topic.
