> For Americans in the top third income bracket, 64% are in an intact marriage, meaning they have only married once and are still in their first marriage. In contrast, only 24% of Americans in the lower-third income bracket are in an intact marriage

Is this age corrected, because people tend to be in a low income segment earlier in their careers, and I don't think that “people are more likely to have gotten married the older they are” is surprising.
