You're right, though; there are a LOT of positive and negative correlations you can find on this stuff if you do your homework (which I did). Caucasians seem to have more stable marriages than non-caucasians, for example. And marrying later boosts the probability of success by quite a bit.

Also, by the time you reach 45 years of age, you're no longer a spring chicken and aren't really incentivized to leave the marriage, anyway.

But you're wrong about the stats being inaccurate (perhaps not about them being "misleading"): I did my homework here, and overall it seems to be somewhere between 30-50% chance of dissolution in the first 25 years of marriage, depending on how you tweak the input variables. And that stat gets worse and worse on every Nth marriage after the first... which is exactly why many people whose first marriages don't work out ever get married again.

For what it's worth (and this is all anecdotal evidence), 100% of the numerous divorces I've seen in my circle were by college-educated people.
