Having merged three main datasets of UFO sightings, we observe that there have been several incidents of such sightings in the last 100 years. As a major component of our dataset is the sightings reported in the US, we see that it is dense here. Further sightings in the UK are also dense, but turn to be more sparse in countries like India, China, and countires in South America.
