Of the total membership of AA in Finland with at least 1 yr of sobriety, close to 90% continued as sober members for another year.
Of those having reached 1 yr of sobriety, about two-thirds survived to the next year.
The survival rate of members with between 2 and 5 yrs of sobriety was about 85%.
Among members with more than 5 yrs of sobriety, the survival rate was above 90%.
The sober membership of AA represents between one-third and one-fifth of general population survey estimates of the number of abstaining former frequent drinkers with concerns about losing control over their drinking behavior.
