The WT org is very clear that it wants young born-in JW's to commit to membership by baptism before they become teenagers. Depending on the family situation, pressure is put on parents (by their parents and others in the congregation) to get their youngsters baptized.
As these kids become adults many stay 'active'. But these folks are very different from when my generation was that age. I call them 'floaters'. They get dressed and make the meetings and are sorta regular in field service. They've learned to stay under the radar - play by the rules and keep out of judicial trouble. They know the rules. They don't know the Bible.
They believe the major WT doctrines - but the end times dogma is downplayed to a 'maybe the end will come sometime soon'. They're all into social media, the new music, hipsterisms and psudo environmental awareness. They pose as the 'cool' Witnesses with edgy clothes, iPads & video games. They have limited education and minimal earning power. They continue to depend on their parents for emotional and/or financial support. They marry each other and have babies. The cycle continues.
