Shrinkling
Since leaving the LDS faith and researching many other faith traditions to understand how my identity was so intertwined with the church I have been collecting some data.
I have attended the Unitarian, Lutheran, Evangelical, Catholic, Protestant (basic), Anglican, and Pagan outdoor churches near me. Many, many have aging congregations. But! The more liberal the church the less (!) congregants and the higher the ages. The more high demand and fundamentalist the group the more and younger the congregants got! I was surprised.
My hypotheses for these are 1. The rise of Christian Nationalism makes evangelicalism popular now 2. Uncertainty - political, economic, societal causes people to seek hierarchical structures with strong male patriarchal leadership 3. White flight - Racism and fear of LGBTQ issues might cause too much cognitive dissonance and ethical questions about God, theology, history might arise threatening ego, so going to a congregation where group think happens feels good.
With this info, maybe The LDS church restricting and keeping a tight grip on obedience and fundamentalism may be a short term strategy that works.
Ultimately it felt like religion was on a sharp decline overall. Small congregations, very few youth and children, and empty parking lots were the norm. The Wild Church movement that included meditation, walks in nature, and sharing time seemed to get the most participation from children/youth/parents/elderly all together.
