Question: What is the success rate of Alcoholics Anonymous? I have never seen it published.
Answer: Every few years, Alcoholics Anonymous does a survey of its members.
In 1992, a random survey of 6,500 A.A. members in the United States and Canada revealed that 35 percent were sober for more than five years, 34 percent were sober from between one and five years and 31 percent were sober for less than one year.
