This sounds like good news. Normally I feel that I am in a very small majority trying to get my mortgage paid off while my children are still in grade school.
Gallup has a few polls regarding Mortgages and Home Equity Loans and Lines of Credit.
The first one that I wanted to mention says that "59% of the people have a fixed rate mortgage and 9% of the people have a variable rate mortgage." (April -May 2005)
Another Gallup Poll indicates that "85% of the people aged 30-49 have a 1st lien mortgage; 78% of the people aged 18-29; 61% of the people aged 50-64; and 24% of the people aged 65 or older." (October - December 2006)
