I am sorry, but I do not understand what the distribution means. For example, does 1 in 624 mean 1 out of 624 drivers of all vehicles at all times of the day and night? Or is it 1 of 624 motorcyclists between the hours of 5 and 8 am during summer months? How does one know? I hope that one can at least look at the states comparatively, but if each state provided it's own data, how does one know that the criteria for reporting is the same for each state?
Also, I am sure others have also considered that the statistics here are represented by an insurance company which may have a vested interest in over representing deer strikes to rationalize higher driver premiums.
Once again, sorry to bring this up. I am potentially very influenced by data such as this, as other drivers may irriate me but potential collisions with animals such as deer worry me. However, it's hard to be impressed by the data representation, without more information.
