The most significant thing is the number of Unitarian congregations. Although you would have thought this kind of thing is what would be included in the General Assembly Annual Report, and discussed at the Annual Meetings, it's actually in the Directory that you get a clearer picture of the health of the Unitarian community.
So 2010-2011 Directory tells me that there are 173 member congregations in Great Britain. This is down 2 from last year. And trawling through the pages you can work out that Bournemouth Unitarian Church has died in the last year, as well as Exeter Unitarian Fellowship.
I've only been getting directories for five years but I can tell you that in five years 8 Unitarian congregations have died.
I'm not prepared to say "this is a terrible thing, we should do all we can to make sure no more close down" because I'm not sure that's a good use of national resources. If a congregation's within 5 years of dying, then I'm not sure it's a good use of resources to try to extend that life. The question is what congregations could survive, grow, and prosper if they received appropriate support? And which ones need to be left to slip away?
And when do we consider the possibility of starting new congregations?
