Two interesting maps of Britain
One is just to say "holy shih tzu! Look at all that snow."
The other is this map from the Unitarian Communications blog which shows the location of every Unitarian congregation in Britain:
I find it really interesting to look at this distribution, which is so obviously uneven. A few observations:
You can see the "Black Spot" from space! (small rural area in west of Wales containing many Unitarian chapels)
It's obvious that there are many more congregations in the northwest than in the southeast, even though the population in the southeast is much bigger.
It's easy to spot places with no Unitarian churches. What do you do if you're a Unitarian in Carlisle? Or somewhere like Bedford when you're pretty equally far from Cambridge, Northampton, and St Albans?
Conclusion: There's a lot of scope for church-planting.
