Divorce Predictor #1: You are a married American.

If you are a married American, your marriage is between 40 and 50 percent likely to end in divorce. Although the national divorce rate has steadily dropped since peaking at 50 percent in the 1980s, the prevalent public opinion is still that half of all marriages end in divorce. According to The National Marriage Project’s “State of Our Unions” Report for 2009, modern marriages are getting more and more resilient because people are getting better and more careful about picking their significant others.
