Keeping one's vows till death do you part is a challenge for even the most happily married couples—but the odds might be greater depending on where you live.

To find out which states have the highest and lowest rates of divorce, 24/7 Wall St. examined a Census Bureau survey to compare how many US citizens were married in 2015, and then how many divorced the following year.
