Bigfoot lives out west and prefers Missouri to Kansas: All reported Sasquatch sightings since 1921 are plotted on just one map A new map that plots out every reported Bigfoot sighting in North America for the last 92 years reveals some very interesting patterns, whether you believe in the mysterious beast or not. PhD candidate Josh Stevens mapped out the 3,313 possible Sasquatch spots since 1921 and people do seem to glimpse the hairy creature much more in some regions than others. The map and data collated by the Bigfoot Field Researchers Organization show, for example, that Bigfoot has supposedly been spotted three times more often in Missouri than neighboring Kansas. Spotting a sasquatch? There are regions of U.S where sightings are very common, despite a low population. And most of them are in the West Stevens explains on his website: 'Right away you can see that sightings are not evenly distributed. At first glance, it looks a lot like a map of population distribution. This makes sense - by a law of averages you would expect an area with more people to report more possible Sasquatch viewings. Even so, there are some very bright spots around the Ohio River Valley, Mississippi River Valley, the Sierra Nevada mountains, central Florida and the Pacific Northwest. Yet it gets intriguing when Stevens maps the relationship between reported sightings and population density (right). As he notes: 'There are distinct regions where sightings are incredibly common, despite a very sparse population. On the other hand, in some of the most densely populated areas sasquatch sightings are exceedingly rare. Most of these Bigfoot hot spots are in the Western United States. Stevens acknowledges that 'terrain and habitat likely play a major role in the distribution of reports.' Proof? There is still debate over the existence of the sasquatch and grainy photos such as this one are often dismissed as hoaxes He notes that the population data is based on Census figures that only take into account where people live, not where they vacation or travel. Stevens also says that the reporting mechanism is not hugely precise as the Bigfoot Field Researchers Organization (BFRO) only allow spotters to enter the nearest city. If you're keen to see a sasquatch yourself, the BFRO offers four-day expeditions into the North American wilderness to try and find the mysterious ape. In 2013 there are still spots left on the trips in British Columbia, North Carolina, Georgia, and a major sasquatch hotspot - Missouri.
