I came into the AA fellowship in 1984. There were some 4 Groups at that time in Bangalore, with some 15 active members or thereabouts. Since then AA has grown in leaps and bounds in membership in some pockets of India while lagging behind in others. But it has grown in geographic reach to cover most states and many cities and towns, even some rural areas.
Yet the "service structure" of the fellowship has neither adapted to the geographical reach, decentralising to be effective, nor has it promoted the 12 steps of recovery, resulting in less than about 7-10% of members remaining active after a year or two. The percentage of drop outs has been unhealthy to say the least.
