It is easier to pump up numbers in 3rd world countries. "Open air" kingdom halls using benches for seats. No internet or groups like this one in the native language. Wider acceptance of what a "publisher" is- many semi-illiterate members fuzzy on exactly WHAT the doctrines are. ie: everyone "partakes".
From personal observations and local feedback in California, about half of the publishers miss most or all meetings since COVID, pretending to tune in online. The majority of JW kids have drifted away. The 4th generation of my 200+ JW family is mostly gone.
Quakers once common, are rare. Christian Scientists are rare. In time, JWs will be rare in the USA. IMO.
