While the overall divorce rate in the U.S. has been declining, "gray divorce" is on the rise, accounting for about a quarter of all divorces. A half century ago, less than 3 percent of people in this country over 50 were divorced. Currently, more than 15 percent of people in that age group have ended their marriages.
The overall acceptance of divorce is no doubt one reason for this phenomenon. Further, by the time many people reach their senior years, they've already been through one or two divorces. That puts them at greater risk for yet another one.
