I've seen it but don't have it on hand. Urban prices certainly seem to have disconnected quite hard from suburban/rural ones, but even suburban/rural might not capture it. I grew up in a not-all-that-wealthy town in Maine about the same size as Watertown, NY--a little smaller actually; an empty half-acre lot there costs more than $120K. (I'd love to move back there, but a house the size of my Boston-area house costs the same as my Boston-area house...)
