(CNN) - A new U.S. Census report found that in 2009, the Southern part of the country had the highest rate of divorce, and couples in the Northeast had the most staying power.
Researchers said this is because more people get married in the South, and couples in the Northeast get married later in life.
The statistics are part of the Marital Events of Americans: 2009.
The study examines marriage, divorce and widowhood in America.
The national divorce rate was 9.2 for every 1,000 men and 9.7 for women.
In the South, the divorce rate was at least one point higher for both sexes.
