I think the granularity of this map is far too coarse grained. Forks, WA and Seattle are in the same bucket. Same with San Jose, sharing the same bucket as Ukiah. The "Greater Portland Area" stretches all the way to the southern border of Oregon.<p>That said, there's still some surprising results. I would have expected NYC to be on par with Western Washington and the Bay Area, but it's significantly less, ~190K vs ~260K.
