UFO Reports & Hotspots

Many UFO reports are located within the same area therefore resulting in 'UFO Hotspots'. These areas of high 'alien activity' are where most 'extraterrestrial experts' go to collect findings.

However, this map is not in direct correlation with the following:

As you can see, the first map shows the highest activity in the west whereas this is the opposite for the one above where most are reported in the east. This may be because the studies were performed in different years or it may be completely biased.

UFO reports from 20 towns across America have been categorised by the number of sightings reported alongside the percentage of sightings per population. As you can see, the percentage per population is miniscule and makes you wonder whether these sightings are true or simply a hoax.

These are the UFO 'hotspots' across the UK. They are categorised by the number of UFO sightings per county since 1961; however, 34 in West Yorkshire, for example, the highest activity on the map, is such a small number of reports in a total of 50 years.
