Just checked out a website called, DivorceRate.org and saw very interesting statistics:

64.2 % of women that get married at age 24 or younger will get divorced. 50.5 % of guys that get married at age 24 or younger will get divorced. According to this site it progressively gets lower percentages. For instance, the divorce rate for women who get married between ages 25-29 is only 16.4% and those who get married between ages 30-34 is only 8.4%.

The ages of 18-24 is clearly an identity formulation stage of life. Do you think that contributes to this?
