Just a reminder that the Priceonomics blog is self-promotion designed to show clients they can get people online to viral-market the website/brand/service for them. The data and how it is presented may or may not be true, but it will definitely be about profitable content. As most of the consumers here seem to respond to the content by clicking through, upvoting, adding personal anecdotes, (perhaps sharing on FB or Twitter?) I'd guess this will be a successful advert. Perhaps somebody trained in handling data could explain why 10 responses is enough to reflect the rest of a states population. Is it significant that out of 60,000 private data sets the company didn't have 10 from Vermont or South Dakota? If we're drawing conclusions based on geography, shouldn't we be able to determine which states have over 1000 responses, and which have less than 100?
