There is no specific distance from which a person can fall and have it said they will survive or not survive. There are simply too many variables that will dominate the factor of "distance."
In 1971, flight attendant Vesna Vulović fell 10,160 meters (~33,300 ft) and survived without a parachute. On the other hand 556,000 people died in 2013 from slip-and-fall accidents from essentially 0 meters.
Any studies I could find cite too many variables such as your physical condition, what you land on, the orientation of how you land, any obstacles that may have changed the way you fell, how fast; even what you are wearing can change survivability.
Anecdotally, pole workmen and tree arborists seem to cite 9 meters (~30 ft) as the "cutoff" for fatality in a fall — that is, most who fall from thirty feet or higher die. Figure that after only 27 meter (~90 feet) of free fall, you are traveling over 80 km/h (~50 mph). Survivability at those speeds is just not that high.
