TK on Jan 21, 2014 ▲ 1 ▼ I'd search for a business selling business statistics based on business licenses (only way to get proprietorships in the mix that I know of). I don't think every business in the US is on Yelp...yet... Anon E Mouse on Jan 21, 2014 ▲ 6 ▼ I would contact the Yelp PR department to help me track down that information.

Jevan Pipitone on Jan 27, 2014 ▲ 0 ▼ What I mean is, it says "Showing 991-1000 of 83350" when searching for san francisco CA, but down the bottom it says page 100 of 100 and the last business number listed is 1000. http://www.yelp.com/search?find_desc=&find_loc=San+Francisco%2C+CA&ns=1&ls=f89b8737a9e121df#find_loc&start=990 Jevan Pipitone on Jan 27, 2014 ▲ 0 ▼ just ask Google.com Adikin on Feb 2, 2014 Interviews > Software Engineer > Factual Add Answers or Comments To comment on this, Sign In or Sign Up.
