Marriage facts, studies, and statistics are regularly compiled and studied by government agencies, psychologists, and sociologists.  The following list was drawn from research and studies on marriage about intimacy, conflict management, extramarital affairs, and other topics. After reviewing this page, you may want to review marriage books as well that tell about how to resolve relationship issues.


  1. About marriage and money: Married adults at any income level were as likely, if not more likely, to report being happy than even the wealthiest unmarried adults. (Warner)
  2. About marriage and divorce: Younger people in the U.S. who are marrying for the first time face roughly a 40-50% chance of divorcing in their lifetime. (U.S. Bureau of the Census, 1992, p. 5).
  3. About divorce and extramartial affairs: 80% of those who divorce during an affair regret the decision. (Hein)
  4. About divorce frequency: A couple gets divorced every ten to thirteen seconds. (Hein)
  5. About the length of marriage: Of first marriages that end in divorce, many end in the first 3 to 5 years. (U.S. Bureau of the Census, 1992, p. 4).
  6. About marriage and happiness: About 64% of married people say they are very satisfied with the way their personal life is going, compared with 43% of singles. (Warner)
  7. About divorce and anger: For ten years following a divorce, 50% of women and 33% of men remain angry. (Hein).
  8. About marital conflict and stress: Poor conflict management in marriage predicts both marital distress and negative effects on children (e.g., Gottman, Markman & Hahlweg, Clements, Stanley, & Markman, 1997, Cowan & Cowan, Grych & Fincham).
  9. About relationships after divorce: After divorce, it is more difficult for women to start new relationships than for men. (Hein)
  10. About marital problems and work: When spouses have marital problems, they tend to work less efficiently on the job, particularly men (e.g., Forthofer, Markman, Cox, Stanley, & Kessler).
  11. About issues before marriage: Studies show that issues present before a couple gets married can predict which couples stay together with accuracies of 80% up to 94% (e.g., Clements, Stanley, & Markman, ; Fowers, Montel, & Olson; Gottman; Karney & Bradbury; Kelly & Conley; and Rogge & Bradbury).
  12. About infidelity that ends a marriage: Affairs that end marriages are subject to the same emotional stresses as the marriage but are twice as likely to split.  (Hein)
  13. About intimacy and infidelity: Affairs die for the same reason as marriage, lack of intimacy. The average affair lasts two to four years. (Hein)
  14. About happiness and finances: While 72% of respondents with incomes of $75,000 or higher report being very satisfied with their personal life, only 36% of those with an annual income of $30,000 or less say the same. (Warner)
  15. About extramarital affairs: More than 50% may be involved in a current affair, yet only 25% cite an affair as an actual reason for divorce. (Hein)
  16. About living together before marriage: Many more couples live together prior to marriage than in the past–recent estimates are in the range of 60+%. Couples who live together before marriage are less likely to stay married. (Stanley & Markman, Bumpass & Sweet).
  17. About problems in marriage: Married couples claim to argue most about money and secondly about children. (Stanley & Markman).
  18. About divorce rates and infidelity: For marriage partners in an affair, the divorce rate is much higher. (Hein)
  19. About marriage and health: Married men and women in all age groups are less likely to be limited in activity due to illness than single, separated, divorced, or widowed individuals (National Center for Health Statistics).
  20. About marriage and happiness: At least one comprehensive study indicates that people are no more happy after marriage than before. Psychologists who conducted the study explain that after major life events (good and bad), most people return to their normal levels of happiness. (Lucas)
