The numbers don’t add up where I live. I would say that 25 percent of the congregations have closed in Canada in the last 20 years and the Kingdom Halls have been sold off.
The borg hasn’t reported numbers decreasing but where are all the people? Our circuit used to have 2 assemblies with 800 attending each side. We now have one assembly with 1100 to 1200 attending. That indicates a 25% decrease at least where I live.
