A GIS-Based Examination of UFO Sightings Across the Contiguous United States (1910–2014) and Their Links to Population Density, Population Movement, and Military Proximity

To the point

A GIS-based study of UFO sightings from 1910 to 2014 across the contiguous United States finds more sightings where population density is higher, timing patterns are unclear, and links to military bases are mixed.

A GIS-Based Examination of UFO Sightings Across the Contiguous United States (1910–2014) and Their Links to Population Density, Population Movement, and Military Proximity

Hannajane Prichett's master’s research, advised by Chris Lukinbeal, uses GIS-based exploratory spatial analysis of UFO sightings across the contiguous United States from 1910 to 2014 to examine relationships with population density, population movement over time, and proximity to military installations, finding a positive association with higher population density, inconclusive temporal patterns from a mean-center analysis, and mixed links to military installations, thereby illustrating the value of GIS approaches in studying extraterrestrial phenomena.
