(statistics pulled from an old post of mine)
Deer tags issued every year: 110,000 (average)
Deer killed by hunters: 22,000-33,000
Number of people in the mountains, all at the same time, chasing after those 22k-33k deer: more than 450,000
Deer killed by vehicles in 2006: 11,000 (estimated)**
Deer dying of old age every year, in the Salt Lake Valley or adjoining canyons, because there is no hunting, or the archery-only areas are incredibly hard to access: more than 3,400 (not counting vehicle kills, poisoning from people feeding them, predation, or anything else - that's just "natural causes")
**(In the year that this number was reported, the state estimated that they only knew of about 12% of the vehicle kills. When you apply that figure to the known kills, you get a result that says 91,000+ deer die to vehicles every year. ....That's really hard to believe, since Utah's herd usually hovers around 165k-195k animals. Somebody needs to check their math again.
