Anecdotal observation from my child's experience is nearly everyone who dropped out dropped out as a cub scout. That was a very large fraction. Those who crossed over are typically Eagle Scouts. But for one of those kids, they were all highly scheduled. But for a different one, they were each complying with parental wishes.

My child was over Cub Scouts by Bears.

But more than a decade later, my grown-ass child hangs out with several of the Eagles. They are close friends.
