About the circuit I grew up in:
Last decade, a congregation was dissolved.
Last year, about a half a dozen or so congregations meeting in a double-hall got re-orged and it works out to one less congregation. They received all new territories, bodies of elders, publishers. The identity of the former congregations got put into a giant “theocratic” blender.
This year, two congregations that met in one hall were merged.
Of course, I’m relatively out of touch with the circuit, since I’ve been faded for over a year. However, in the last decade, the congregation is three less congregations (at least). I believe it is indicative that in the US English-speaking territories, there is a gradual decline.
From what I've gathered, re-orgs are now common in many places.
How about in your area? Any signs of decline?
