Jumping off a bridge?

[Willdieby30]

does anyone know the probability of death if one jumps off a bridge, or statistics on the matter? I would be falling into water.

It depends on the fall distance. The Golden Gate Bridge is like 220 feet, and about 2% of people survive that fall.

it would be more like 100ft

it would be more like 100ft

Its possible youd die, but 100 ft onto concrete would be a better option.

Maybe if it was cold cold water, so even if you survive youd lose the feelings in your limbs soon after entering the water.

I'm looking at a height of just under that, from research I have been told just make sure you fall right and aren't drunk,

Jumping off a high building - Lost All Hope

Whilst jumping from height can be a very effective method of suicide (providing it is from sufficient height), it does not account for a particularly high percentage of suicides in either the US or the UK. Having said that, in Honk Kong it accounted for over half of all suicides in 20061, so...

Jumping off a high building
Whilst jumping from height can be a very effective method of suicide (providing it is from sufficient height), it does not account for a particularly high percentage of suicides in either the US or the UK. Having said that, in Honk Kong it accounted for over half of all suicides in 20061, so easy access to tall buildings seems to impact the propensity to use this method.
The most important factor in suicide by jumping is height. Stone2 states that jumping from 150 feet (46 metres) or higher on land, and 250 feet (76 metres) or more on water, is 95% to 98% fatal. 150 feet/46 metres, equates to roughly 10 to 15 stories in a building, depending on the height of one story. 250 feet is the height of the Golden Gate Bridge in San Francisco.
Ideally, anyone jumping on land should try and land on their head, as this maximises the chances of fatal head injuries. In a study by Goonetilleke3, head impact was the most frequent landing area in fatal falls. If a person is jumping from lower heights, going head first becomes even more important, as the chances of death reduce the shorter the drop, and brain haemorrhage is the most frequent cause of death for jumpers.
It should go without saying that great care should be taken when jumping to not land on any person, or anything that might break the fall. It is also important to land on something hard, and not a forgiving surface like soft grass or sand that might cushion the fall. High cliffs with rocky landings are likely to fulfil the requirement for height, a hard landing and not having anyone underneath. Beachy Head in East Sussex, UK, is a notorious suicide spot for this reason.
Although the causes of death by jumping off a height into water differ to those on land, jumping feet first should be avoided as a perfect entry into the water may end up in survival, but with significant spinal injuries. Jumping from 250 feet means the speed of impact to the water is over 70mph, but whilst deceleration on a hard surface is instant, in the water deceleration is slower, and death tends to be caused from fatal chest injuries4. Really, jumping from this height it should not make an enormous difference what part of the body enters first.
There is one essential point to be made when considering jumping as a method of suicide - jump from too low, and there is significant risk of non-fatal injuries. Stone2 presents worrying statistics from a number of studies showing a high percentage of people jumping from four stories or less. Of those, a high percentage survive, invariably with fractures to spine, pelvis or major bone. Landing on the head can cause brain damage. Even jumping from seven stories can have a decent survival rate.
Jumping off the Golden Gate Bridge still does not guarantee death, as a study of 885 jumpers found that 19 (around 2%) survived5,6, although it is likely some (undiscovered) suicides did not even make it to the statistics, meaning the likely true percentage of survivors is less than 2%. Still, the point is that it is possible to survive even jumping from a renowned suicide spot. Jump off a lower bridge and the chances of survival will be much higher.
Possibly the reason jumping is not a popular suicide method is that self-preservation instincts can prevent someone from making the jump, and there can be time to reflect and decide against jumping on the journey to the chosen jump site, or even on the edge of it. So anyone considering this method needs to consider this, and plan their location for jumping very carefully.
Providing the jump is from sufficient height, certainty of death is very high. Jumping from insufficient height gives a fair chance of survival, with high probability of significant, and often long term, physical injury, plus possibly brain damage. As such, this method is not recommended for a suicidal gesture.
Whoever discovers or has to identify the body is likely to be faced with a particularly gruesome corpse, especially if the jump has been on land."

I know it's not specific but maybe it helps.

so basically headfirst

Its possible youd die, but 100 ft onto concrete would be a better option.

idk about getting to a roof top... a bridge is easier for me tbh

Obviously easier said then done.

Survival following a vertical free fall from 300 feet: The crucial role of body position to impact surface - Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine

We report the case of a 28-year old rock climber who survived an "unsurvivable" injury consisting of a vertical free fall from 300 feet onto a solid rock surface. The trauma mechanism and injury kinetics are analyzed, with a particular focus on the relevance of body positioning to ground surface...

Heres is a link from a biomedical journal which suggests the falls from anything above 100ft carry 90% plus fatality rate. But there are so many factors that can affect that too. Incidentally the case study is actually on a woman who survived a 300ft fall from a rock cliff face. So there's that...

Oh, good grief! All of that misery just to climb a bunch of rocks?! Rock climbing or jumping takes a lot more nerve than I have - the original born-again chicken. Am really in awe of you courageous ones who are considering jumping! I suppose if I had been on one of the top floors on 9/11 with fire at my back, there would have been no choice. Poor souls!

 

[Soulless_Angel]

so basically headfirst

Yep, not quite sure how to ensure you go head first but hey ho... I am sure if you jump right it can happen, more research I need to do!

is this from that book by geo stone?

It was from the lost hope website. The article on the website itself, cites a couple of different references. But yes, Geo Stone is one of them.
