Oh... I get to validate what you posted.
Heh. Wouldn't you regardless? Anyway, I found the divorce rate among those who use NFP.

And I found an article by Msgr. Pope regarding Catholics and divorce, however, it's not based at all on daily Mass Catholics which is what I was referring to, so while the divorce rate is better than Protestants, it still is not good:

I could get in touch with Msgr. Pope requesting the divorce rate of daily Mass Catholics who attend together, but he might answer, "What divorce rate?"
Actually, there were some on the chart I saw many years ago, but the percentage was very slim. Under 4%, more like 3 or 2 .... but again, I can't remember exactly. But look to the NFP numbers; they'll tell you what you need to know. Following Catholic teaching will allow you to be healthier and happier.
