SBF:AuldSoul had it right when drawing to your attention that I was refering to the 2002-2006 period.
I left the JWs January 6th 2002, and later that Summer I was invited to speak at the SU I refered to. Four years later I was asked to speak again and the attendance was a poor week at over 80. Meanwhile I had kept an interest in how they were doing, and had those figures reported to me. They regularly get over 100 in attendance.
You're correct in stating that the church has been in general decline, but the last four years has seen a resurgance that your figures don't reflect given that, while they are the most up to date comprehensive study, they only reflect up to 2002. I recall seeing those figures towards the end of 2002 when attending a multi-denominational Evangelical conference in Stirling, where I got to discuss such concerns with some of the hundreds of Ministers in attendance. It was a real issue, and stirred them to action. It appears that action is bearing fruit, whereas selling dusty magazines doesn't inspire the just-around-the-corner movements.
Are you disgruntled to find that Christianity is enjoying a different providence to JWs in Scotland? You certainly came across as though someone had peed in your chips...
