Actually, the percentages of registrations are much higher...approaching 40% now that many other units have been forced or have chosen to recharter with unaffiliated churches or organizations.
In this article, they state 38%...but it varies.
[Just for edification, not every Scout unit is chartered with a church. It does make it convenient and is quite helpful in espousing and teaching a solid moral foundation, but not mandatory.]
What I can tell you is that in my experiences, the actual number of participants is a fraction of that, yet the LDS pay for ALL youth registered in the church as members, active or not. Unless a parent opts their child out, all boys 8-18 in the LDS church are registered automatically.
It’s the LDS church’s youth “program” for boys.
Mormons are the most conservative voting block in the country. They must also be the most unconcerned about their children, too. It doesn’t fit.
