They keep switch the territories around , so my guess is you have no idea if the borg is growing or declining. Our assembly had about 3500 in attendance with a population base of maybe 1.8-2 million people. It use to be one province, 1 million people and 5000 in attendance. Now they are starting to lump provinces together.
Still lots of young families which is something I find really sad. Even since covid , it doesn't surprise me. People want to believe in some against the grain narrative to feel special.
