We’ve all heard that 50% of marriages end in divorce. This statistic seriously undermines the institution of marriage. After all, how important can marriage be if it’s success can be predicted by a coin flip?
Defining the divorce rate for first time marriages is more complicated than it would seem. The average is probably between 42% and 45%  but it varies wildly based on certain risk factors. For example, if you are over 25 years old, college educated, have an annual household income over $50,000, have a strong common faith, and have not lived together prior to marriage; your chance of divorce is close to zero.
On the other end of the spectrum, if you and your spouse are significantly different in age, have lived together prior to marriage, have only a nominal faith, and both smoke; your chance of divorce is significantly higher than 50%.
