Are Entrepreneurs Getting Older Or Is Society Getting More Entrepreneurial?

Paul Kedrosky has a post that links to a new report on the average age of entrepreneurs. Surprising to some, the age skew is much older than expected.

This makes me wonder is it's actually part of a more general trend. With the rise of what Richard Florida calls the creative class, the growing emphasis on quality of life, and the fact that people are changing jobs and careers more often than ever, it might indicate a shift from traditional companies and workplaces unable to hold employees who are going to be leaving for start ups and more creative opportunities regardless of their age.

And it begs the question, are entrepreneurs getting older or are we as a society getting more entrepreneurial?
