Is it any coincidence that as the credit crunch bites and negative equity is around us again that the divorce rate is at its lowest for 26 years?

Figures just released show the divorce rate fell to 1.19% in 2007 down from 1.22% in 2006.

Could the main reason for this being couples not being able to sell  their homes and therefore having to stay together, where as previously they would have divorced?

Is negative equity slowing down the divorce rate by creating negative matrimony ?
