Where the figures come from
The Church of Jesus Christ of Latter-day Saints reports its membership to the U.S. Religion Census by county: members of record and their children, attached to local wards and branches. It is a membership record kept by the church, not a survey of belief or attendance.
A Mountain West church
The church's share of the population falls off sharply with distance from Utah. After Utah and Idaho come Wyoming, Arizona (6.1%) and Nevada (5.9%), all bordering states of Utah or of Idaho. Hawaii (5.2%) is the exception, far from the Mountain West. In half of the states the share is below 0.8%, and across much of the Northeast and the Great Lakes it is at or near 0.4%1.
In Utah and Idaho the church is the largest religious body by a wide margin: it accounts for 85.4% of all adherents counted in Utah and 47.6%1 in Idaho. It is the largest body in no other state.

By number of members
Counts favor large states. California has the second-largest membership (756,507) even though Latter-day Saints are only 1.9% of its population. Texas (362,037) and Washington (289,479) also have more members than many Western states with higher shares. Arizona, with 436,521 members, has nearly as many as Idaho1 on a population almost four times as large.

Growing in number, not in share
Between the 2010 and 2020 studies the church's membership in Utah rose to 2,126,216, up from 1,910,504 in 2010, but its share of Utah's residents went down from 69.1% in 2010: the state's population grew faster than the church. Idaho's membership went up from 409,265 in 2010. Nationally the church counted 6,721,031 members, up from 6,144,582 in 2010, and its share of the population was unchanged from 2.0% in 20101. The 2010 figures come from the separate 2010 study file, measured against the 2010 Census population.
Pitfalls
- Membership records. The count covers everyone on the church's records in each ward, children included, whatever their level of participation; it is not a measure of how many residents practice the faith.
- Residence. Members are counted where their ward meets, which can differ from where they live near state lines.
- Other Restorationist churches. The Community of Christ and smaller related churches reported congregations only, so they are not in any adherent figure here.
- Survey figures differ. Surveys that ask adults their religion give different shares; see the religion overview for how the two kinds of data compare.
Questions about Latter-day Saints by state
What percent of Utah is Mormon?
The Church of Jesus Christ of Latter-day Saints counted 2,126,216 members in Utah in 2020, 65.0% of the 2020 Census population. That share is down from 69.1% in 20101, because Utah's population grew faster than the church's membership there. The count is the church's own membership record, not a survey of what residents call themselves.
Which states have the most Mormons?
By number, Utah (2,126,216), California (756,507), Idaho (462,069) and Arizona (436,521). Utah alone has 31.6%1 of the church's members in the United States.
Is "Mormon" the same as Latter-day Saint?
This page uses the church's full name, The Church of Jesus Christ of Latter-day Saints, and calls its members Latter-day Saints; "Mormon" is the word many people search for. Other churches with roots in the same movement, such as the Community of Christ, are separate bodies and are not included in these figures.
