Does your area have a lot of\u00a0sole proprietors -- have you ever wondered? \u00a0And what about startups -- will you find other startup entrepreneurs in your chosen city? Using the ZoomProspector website I ran some heat maps that show concentrations of\u00a0sole proprietors and startups across the United States.\u00a0 The results were surprising. Let me start with the sole proprietors.\u00a0 Here is\u00a0a heat map\u00a0showing the sole proprietors\u00a0across the U.S. --\u00a0the lighter the\u00a0yellow color, the\u00a0fewer sole proprietors; the darker the red color, the more there are: For comparison, I then ran a heat map showing the population density across the U.S.: As you can see, the two maps\u00a0look almost the same. At first I thought there was a mistake. But upon closer examination I do see some slight differences.\u00a0 What this means is that sole proprietors are pretty evenly dispersed\u00a0in ratio with\u00a0the population density. Sole proprietors truly seem to be representative of America, insofar as location. Then I ran a heat map showing startups per 10,000 people.\u00a0 It shows a much different picture: You may not be surprised by the concentrations of startups on the coasts.\u00a0 However, all those wide open spaces in the Western states do seem to attract more than their share of entrepreneurs starting businesses.\u00a0 And surprisingly, there are fewer startups per 10,000 people in places like Silicon Valley, than in places in "the middle of nowhere," as the saying goes. Who says you have to be in Silicon Valley to start a business? To see what else you can do with the information in the ZoomProsector site, I'll point you to John Tozzi's article at BusinessWeek.com called\u00a0"Best Cities for Startups."\u00a0 Using the site, BusinessWeek gathered together 11 data points to come up with the rankings for\u00a0their take on the best city in each state to start a business.\u00a0 The factors they looked at were: ... "based on a formula weighing the following 11 factors: workers with at least a bachelor's degree (2008); white-collar workers (2008); "young and educated" population (2005-07); workers in "creative" professions (2005-07); international talent (2005-07); universities (2007); patents (2007); venture-capital funding (2006); small businesses per capita (2008); sole proprietors per capita (2005); and startups per capita (2004-05). All data was compiled by ZoomProspector." You may just be surprised. For instance, in California, it's not San Jose or Cupertino or Palo Alto or San Francisco that BusinessWeek rates as the best city for a startup. It's Irvine.
