The Golden Gate Bridge is not only the most popular place to commit suicide in the United States but the most popular in the entire world…At such a speed, water has proven to take on properties similar to concrete. Because of this, most jumpers die on their immediate contact with the water. The few who survive the initial impact generally drown or die of hypothermia in the cold water.
People have been known to travel to San Francisco specifically to jump off the bridge, and may take a bus or cab to the site; police sometimes find abandoned rental cars in the parking lot.
The fatality rate of jumping is roughly 98%.
