The internet has severely slowed the "potential" growth of the org. What's the first thing someone that is interested does after an inspiring introduction at the door from a witness? They either get online and see what's really up, or if they're too old to get online (and/or don't know how to do that), they call their sons or daughters and scare them that their mom is interested in this strange religion and THEY get online and then report back to their mom to stay away.
The mom then starts hiding from future visits and/or politely tells them she's not really interested.
You can substitute "mom" for "dad" in this example.
Most of the new ones are coming from underdeveloped countries right?
The only new ones are family of ones that are already "in" in our circuit.
