And I don't mean, "full of Ben and Jerry's."
Ran some numbers: if every state (including D.C. and the Virgin Islands) was as densely populated with Unitarian Universalists as Vermont (in the #1 position), there would be more than 950,000 members in Unitarian Universalist congregations today. Think of it as food for thought rather than a meaningful fact. States aren't fungible.
I've left out Puerto Rico because, unlike the others, there are no Unitarian Universalist Association member congregations there, though there is an emerging congregation.
The 52nd position? Hawaii.
