Yes and no. Look at this overlay of population density and Hum locations. Population density is given as the density of red regions on the map, showing of course the very high densities in New England, Los Angeles, and so on.
There is a striking overall correlation between Hum locations and population density in North America. There is a distinct north-south line that divides the highly populated East with the less populated mid-west. That line runs roughly from Winnipeg, Manitoa to Laredo, Texas and Hum reports follow that same line.
There are other obvious tight correlations, but there are also some notable exceptions. For example, look at Regina, Saskatchewan, Canada (population 180, 000), and Saskatoon, Saskatchewan, Canada (population 202, 000). There isn’t a single Hum report among the almost 400, 000 people in those two cities, and only one report for the entire province. This cannot be attributed to lack of access to internet technology or lack of exposure to national stories involving hums or unusual noises. There are places with significantly proportionately more Hum reports, in more isolated locations. For example, Plymouth England (population 256, 000).
And if you look, you can see other population density – Hum report discrepancies. Yes, there are other explanations for such discrepancies, but it seems to make sense to go with what we do know, as opposed to what we don’t know.
With a few thousand more map points, I think the picture will become clearer, but there is of course the possibility that the Hum is blanketing most of the planet’s surface.
