Wife's congregation is much smaller than it used to be. She even told me that the hall feels empty now. It's not empty but definitely less in attendance. I should drive by to check the parking lot during a meeting.
I've got relatives from the Midwest that told my wife, not me of course, that their meeting attendance has gone down a lot in the past few years. They're older and concerned their hall will be sold and they'll have to travel a lot farther.
I've heard a lot more witnesses are using the call in option and listening to the meeting. Probably depends on congregation.
