No doubt, small businesses are a powerful force in the U.S. economy in terms of job creation and innovation. And, according to a recent study from the Kauffman Foundation, it looks like things are still going strong, despite the slowing economy. For example, every month, about 500,000 new businesses are started (of course, there are certainly a good number that fail as well).

So, what are some of the key trends? Well, interestingly enough, there is quite a bit of growth from immigrants. In fact, they are more likely to start businesses than native-born Americans.

Something else: men are twice as likely to start a business then women. Actually, I think this is unfortunate because diversity certainly allows for stronger growth.

However, looking at the next decade or so, I suspect we'll see much more entrepreneurial activity. Why? It's when the Baby Boomers will reach their prime years for new business formation. They will have the wisdom and resources to take a flier. What's more, a new business may actually became an interesting way for Baby Boomers to essentially change the definition of "retirement" -- that is, leaving the rat race and doing what they really want.
