A better question might be
"How many acres per hunter in the area you hunt within the square mile (or greater) where you hunt?"

I'd rather have just 25 acres to hunt bordering 575 non-hunted acres (600 acres per hunter), than have 600 acres being shared with 9 other hunters (60 acres per hunter).

Keep in mind the average range of any particular deer is commonly somewhere in the neighborhood of 1 to 2 square miles. So unless you have several thousand exclusive acres, they are really never "your" deer like so many of us like to think.

Most quality deer management hunting clubs will use a baseline rule of thumb of 100 acres per hunter, such as a 1,000-acre tract with 10 hunters.

More important factors can include how many days those hunters actually hunt annually, how many days an area is even open to deer hunting. Look at President's Island ---- public land with quite a few hunters per acre, but very little hunting annually. Might find better hunting there with 25 acres per hunter than somewhere else with 500 acres per hunter.

Most of the areas I hunt are either large tracts or bordering large tracts, where there is at least a square mile or two with approximately 1 hunter per 125 acres. But the real pressure may be more determined by how much and how hard those nearby hunters actually hunt, as well as what they kill or don't kill.
