I'm confused about the populations. For example, it mentions the population of Kansas City is 143K. Wikipedia says 482,299, and "greater" KC is closer to a million. What exactly is measured here?
They probably should've used metro area, but that might've been a data challenge if they lacked lat/lon for each property.
EDIT: Looks like they're using the wrong Kansas City! That 143K population number is for Kansas city, Kansas, which is much less than half of the total city.
The other half, Kansas city, MO is 482,299, and in the top 50, unlike Kansas City, Kansas.
Probably a bug.
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.
