Ten percent of Arkansans have been married 3 times or more. Five percent of all Americans have been married that much.
I think that explains the famous "50% divorce rate," which is puzzling since most marrieds never divorce. The small numbers of serial divorceniks do it so often that they bring everyone's average down to what seems like a crap shoot.
This reminds me of the solution to the statistical puzzle of the higher intercourse rate of men than women. Gay men account for a small portion of the gap. A bigger part of the gap is closed by a small number of women who have sex with many men - that is, prostitutes.
I think it would be helpful to calculate two divorce rates, one for all marrieds, and one for all marrieds except those who have divorced multiple times.
