What is the age at which first marriages tend to break up?

[bluestateguy]

Since 50% of all marriages end in divorce, I was wondering if there is an age group at which divorces tend to be particularly high.

1. Eight years

According to the Boston Globe, recent U.S. census data showed that the median amount of time before a first marriage ends in divorce is eight years, with separation happening after seven years.

2. as long as it takes to have enough money to afford it.

In my case, 20 years.
