An interesting piece of Monfort's visualization are the maps showing where UFO sightings are reported. Among the countries that see the most UFOs, you find Canada, Mexico, Australia, and Scandinavian nations. For many countries on the low end of the scale, internet access is probably a factor.
However, with this map, it's worth noting Monfort capped the data to keep a readable scale. That's because the U.S. has an insane number of UFO sightings. Americans report seeing UFOs at a rate 300 times greater than any other nation.
