I know not representative but those odds are 50/50, I am sure there are Cirrus forced landing's that are successful that we never get to here about, we always here about the botched ones.
At least in the US, off airport landings usually make the local press and thereby the COPA forums. Statistically, I don't think anyone argues that the odds are in the pilot's favor during an off airport landing. They do seem to decrease as airplane performance goes up. Big jets rarely do well. The BRS record, however, is excellent. Many off airport landings still total the plane even though the passengers survive. The argument gets to be increased risk of death or injury balanced against the chance of saving the plane.
