John Nelson of IDV Solutions has made a map illustrating where UFO sightings have happened the most across the US. He also made visuals to describe how the sightings relate to an area's population density, what times of year UFOs are seen the most, and the trends of UFO shapes over the years.

Most UFOs are seen on summer nights, and while the flying disk was really popular in 1970, aliens have been preferring the fireball in recent years.
