It appears to be using the data from KCK. If it's pulling the population data from there it might be a safe bet that everything else is from KCK, too. That being said, regardless, I think the entire bit about KC being ranked up near San Fran and NYC is way off. There's very reasonably priced housing in the greater metro area. I don't think the sample they're using on this site is very accurate at all. I find it really hard to believe that of all the midwestern places to live on this site, Kansas City is the most expensive in terms of Rent:Buy. 200-300k? This probably isn't true of some of the big swaths of outer KC I've driven through, and it definitely isn't true of the suburban areas. Aside from this little sampling problem, and it's easily fixed, no big deal, I think this site is really cool and a great way to look at affordable places to live.
