"Latter-day Saints still have more children"

That study has 7 to 12% error ranges for the LDS group. Even with that, the share of LDS women with a child at home is 50% more than non-LDS. Lastly, there's a huge difference in rate of decay when a group is at, above, or below replacement rate. If everyone's declining, but they're declining far slower, that still proves my point that the composition of these communities in 80 years could be far different if current rates hold.

Utah has one of the most expensive housing markets in the country, and average children per women is 1.8 in the state. It’s always hard to predict the future, but I argue the evidence is clear LDS fertility rates will rapidly coalesce with others within the next few years, maybe faster if young followers leave the church faster.

US Gen Zers and millennials are leaving the LDS church, data confirms - https://religionnews.com/2025/12/10/us-gen-zers-and-millenni... - December 10th, 2025

> In 2007, according to Pew, the LDS church retained 70% of childhood members in the U.S. (n = 581) In 2014, that was 64% (n = 661), and in 2023–24 it had declined still further to 54% (n = 525).

> That 54% current retention rate looks better than the GSS’ 38%, so that’s potentially good news for LDS leaders. But once again, we’re witnessing a clear drop from the fairly recent past. Both major U.S. surveys that track childhood affiliation are saying that more people are leaving than used to.

> What’s more, this is being driven by younger adults. In the general population, younger adults are noticeably more likely to have no religious affiliation than older adults — either because they’ve left religion or they grew up without one. It shouldn’t surprise us that it’s true in Mormonism as well.

So, the cohort leaving the church the fastest are the ones with fertility. What does this do to LDS fertility rate trends? It likely bends them downward.
