While studying for my Algebra mid-term, I came across some sobering formulas:

d = 4n + 5  percent of divorced at a given year of marriage for women who married                                             before age 18 (<18 yoa)

d = 2.3n + 1.5  percent of divorced at a given year of marriage for women married                                             after age 25  (>25 yoa)


Let’s calculate for the likelihood of divorce at 10 years for each equation:

we will let n = 10 years of marriage

d = 2.3n + 1.5  (% likelihood of divorce, >25)

d = 2.3 (10)+ 1.5

2.3 x 10 = 23 + 1.5 = 24.5% likelihood of divorce at 10 years if female marries at >25 yoa


d = 4n + 5  (% likelihood of divorce, <18)

d = 4 (10)  + 5

4 x 10 = 40 + 5 = 45% likelihood of divorce at 10 years if female marries at <18 yoa


Yikes!  And I have heard that subsequent marriages double these statistics!

People in high-stress careers can also have a difficult time maintaining the marriage relationship.
