I'll also say that your table doesn't say much, only the ages for divorced people were when they married. Nothing that puts it in any context such as at what age most of the population is when they get married (your linnk is dead so I can't see anything). Look at this chart:
It's only in recent years that marriage has been getting pushed back farther. Your data says that 64% of women married before 25 get a divorce eventually and 50% of men married before 25 get a divorce. Well it just happens to be that the
median (as in half above, half below) only went above 25 quite recently. Around the 70's (which is when most of our parents were married) it was 23. I'd like to see more informaiton about the data in your stats but based on that the divorce rates might not be significantly higher for couples that marry before 25 (since my graph shows that most people are married by the age of 25).
We are talking mean vs median so the basis is different, mine also only includes first marriage yours doesn't specify which marriage number it is so there are things to consider. Still I think my link definitely puts some context iinto the discussion.
This is completely speculative but we could also consider whether people that get married later may be more likely to stay in a bad marriage because the threat of growing old alone may be enough to keep them from starting over again (sometimes I wonder if that is the only thing keeing my parents together).
