I'm not sure where that first link is getting its numbers, or why they're so outdated, but the US Small Business Association puts the number of small businesses in the US at around 31.7 million [0], or just over 100 per 1,000 people, which would top that list (excluding Indonesia, which, BTW why is it so high?)
