Looking at the Hum Map can be misleading, because heavy concentrations of Hum reports typically correlate with higher population densities. The regions of interest are where hum reports do not follow population density. One place in particular caught my eye: Vancouver Island, shown in the map below (for reference, Seattle and Vancouver are included in the screen shot).
Vancouver Island is fairly big at over 31, 000 square kilometres (about 12, 000 square miles), but its population is only about 750, 000 people. This generates a per capita Hum report concentration of about 1 Hum report for every 17, 500 people.
Now contrast this with South Dakota:
Four Hum reports among 875, 000 people. That’s a concentration of roughly 1 Hum report for every 210, 000 people. And along with North Dakota, parts of this region are home to one of the best optical fibre internet networks (http://dakotafire.net/article/broadband/). Internet penetration into home ranges from 73% to 80%, depending on the source you use. It could be even higher.
On a state by state or province by province basis and only on this quick and narrow examination, South Dakota has the lowest concentration of Hum reports. But that’s just an initial look at the Map. I expect others to do in-depth looks at the data, and to report more rigorous results.
Do contact me if you notice any Map points that look suspect or are obviously incorrectly geocoded.
