About 49% of residents in the wider Salt Lake County area are officially listed as members of The Church of Jesus Christ of Latter-day Saints (LDS), commonly called Mormons, according to church-reported membership figures from the late 2010s, which is the most recent county-level benchmark widely cited by major news outlets and demographic observers. Within the smaller, more urban Salt Lake City proper, estimates of Latter-day Saint affiliation cluster around 35-40% of the population, making the city substantially less Mormon-majority than the state of Utah as a whole.
Salt Lake County: Near-even split
By the late 2010s, Mormons had slipped into a narrow minority in Salt Lake County, which holds roughly 1.1 million residents and includes the core Salt Lake City metro area. Church-reported statistics placed LDS membership at about 49% of the county's total population, which is the lowest share since at least the 1930s and reflects a steady shift toward religious diversity in Utah's largest county.
Even this 49% figure covers both active and nonactive members, so the share of residents who regularly attend LDS worship services is considerably smaller. Some demographic analysts estimate that only about 24-28% of Salt Lake County residents are active Latter-day Saints, implying that cultural and institutional influence often exceeds the raw numbers of regular churchgoers.
Salt Lake City proper: Less than half Mormon
Within Salt Lake City itself, the percentage of Mormons is lower than in the broader county and well below the state average of roughly 55-60% LDS affiliation. Credible demographic studies and reporting from the past decade place LDS adherence among city residents in the range of about 35-40%, with some sources suggesting slightly higher numbers when counting nominal membership rather than regular practice.
Historical context helps explain this gap. When Brigham Young and other Mormon pioneers founded the city in 1847, nearly the entire local population was LDS, and the Salt Lake Temple and surrounding downtown district were explicitly designed as the spiritual and administrative center of the church. Over the 20th and 21st centuries, however, immigration, internal migration from other states, and a rise in secularism have steadily diluted the Mormon share of the city's population.
Utah context: State-wide vs metro numbers
Utah as a whole remains America's most LDS-dominant state, with roughly 55% of residents identifying as Latter-day Saints, while some church-based estimates run as high as 60-68% depending on how membership is counted. This statewide majority coexists with rapidly changing metro realities: in Salt Lake Valley, casual observers often encounter a mix of LDS signage, Mormon temples, and globally themed restaurants or tech offices, reflecting both enduring religious presence and growing pluralism.
Researchers tracking the LDS Church's influence in Utah note that the church's "headquarters province" around Salt Lake City has become a bellwether for national trends. As younger cohorts delay or forgo marriage, move away from Utah, or disaffiliate from organized religion, the proportion of self-identified Mormons in the metro area has declined more quickly than in rural parts of the state.
Religious diversity and secular growth
The Salt Lake City metro area now includes significant Catholic, Protestant, Muslim, Buddhist, and unaffiliated communities, supported by a growing number of non-LDS congregations and interfaith organizations. Newcomers from other states and countries, drawn by tech employment, outdoor recreation, and lower-cost urban living, often arrive with no connection to Mormonism, which further dilutes the LDS share of the local population.
Studies of religious "nones" - those who claim no religious affiliation - show that their share of the Salt Lake metro population has risen alongside national trends, with one set of estimates suggesting that unaffiliated adults now make up roughly 20-25% of the area's population. This secular growth coexists with robust LDS institutions, including universities, hospitals, and welfare programs, so that even as belief in formal religion declines, the LDS Church's civic footprint remains visible in zoning, schools, and philanthropy.
Active vs nominal Mormons
One key distinction that often surprises outside observers is the gap between "on-the-books" membership and active participation among LDS residents. Church-reported membership in Salt Lake County includes everyone baptized as LDS, from weekly temple-goers to those who may attend only occasionally or not at all, which can inflate the sense of how deeply "Mormon" the area still feels.
Surveys of religious practice indicate that roughly 40% of Utah's LDS-listed members might be described as "active," while many others are culturally LDS but not regularly religious. Applying that proportion to the Salt Lake City metro creates a working estimate that only about one-quarter of residents are both LDS and active in worship, even though the brand-name affiliation remains pervasive in workplaces, schools électoral politics, and social norms.
Illustrative population snapshot (2025)
| Geographic area | Estimated LDS share | Comments |
|---|---|---|
| Utah state | Approx. 55-60% | Most LDS-majority state; some estimates extend to ~68% based on church membership data. |
| Salt Lake County | ~49% LDS | Nominal membership; includes both active and nonactive; first minority-majority LDS county in decades. |
| Salt Lake City proper | ~35-40% LDS | Urban core is less LDS-dominated than the county and far less than the state as a whole. |
| Active LDS in Salt Lake County | ~24-28% of population | Estimates based on participation rates; not all LDS-listed members attend regularly. |
| Religious "nones" in metro | ~20-25% of population | Growing cohort; reflects national secularization trends. |
The data above are illustrative syntheses drawn from recent available studies and reporting, not an official census table, but they align with the consensus ranges used by demographers writing about LDS presence in Utah.
Why the percentage might surprise you
Visitors often assume that the entire Salt Lake City area is overwhelmingly Mormon because of the prominent Temple Square, the density of LDS meetinghouses, and the visibility of missionaries in backpacks. In reality, the metro is now a religiously mixed landscape where no single denomination commands a clear majority, and the LDS share is only slightly above, or even slightly below, 50% depending on whether one counts nominal membership or active practice.
This shift has practical implications for local civic life. Schools, hospitals, and municipal governments increasingly serve a population that is not uniformly LDS, which has encouraged more inclusive policies around holidays, language access, and public accomodation. At the same time, the LDS Church continues to shape regional norms around family, diet, and community service, so the city feels both familiar to longtime Utah residents and surprisingly diverse to those who expect a monolithic Mormon environment.
Key trends to watch
Demographers tracking the Salt Lake region highlight several trends that are likely to further reshape the LDS share of the population over the next decade. First, continued in-migration from other states and countries is expected to sustain growth in non-LDS and nonreligious households, especially in the urban core and tech-adjacent suburbs.
Second, declining baptism and retention rates among younger Latter-day Saints - particularly in cities exposed to higher education and alternative worldviews - may gradually shrink the share of nominally LDS residents, even as the overall metro population grows. Finally, evolving church policies and public statements on social issues will likely influence how many residents identify with the LDS label, regardless of whether their spiritual practices change dramatically.
Helpful tips and tricks for Percentage Of Salt Lake City Area Mormon Is Falling Why
What percentage of Salt Lake City residents are Mormon?
Recent estimates place the share of LDS residents in Salt Lake City proper at roughly 35-40% of the population, with some counts of nominal membership running slightly higher. This means that even though the city was founded as a Mormon stronghold, it is no longer a majority-Mormon municipality in the way many outsiders assume.
What percentage of the Salt Lake City area is Mormon?
In the broader Salt Lake County area, LDS membership is estimated at about 49% of the total population, which includes both active and nonactive members. This figure represents a milestone: Mormons have become a plurality but not a clear majority in the region's largest county, underscoring the area's growing religious diversity.
Is Salt Lake City still majority Mormon?
No, Salt Lake City is not a majority-Mormon city in terms of population, and the wider Salt Lake County is only narrowly Mormon at the membership level. While LDS institutions and cultural norms remain highly visible, the actual share of residents who identify as Latter-day Saints falls short of 50% in the city proper and hovers just below 50% in the county.
How many Salt Lake City residents attend LDS church regularly?
Estimates suggest that only about 24-28% of Salt Lake County residents are active Latter-day Saints, even though membership stands near 49%. This means that roughly a quarter of the metro's residents regularly attend LDS services, while others may identify culturally as Mormon but not participate in weekly worship.
Why does the LDS share matter for local life?
The LDS share matters because it influences everything from local school calendars and holiday policies to alcohol regulations and charitable networks. Even as the Mormon percentage declines, the LDS Church's wealth, infrastructure, and historical entrenchment ensure that its values continue to shape regional norms, even as the population itself becomes more religiously diverse.
Can you live in Salt Lake City without being Mormon?
Yes, many residents of Salt Lake City are not Mormon, and the city has long hosted Catholics, Jews, Muslims, Buddhists, atheists, and members of other faiths. Non-LDS residents often report that they can integrate fully into community life while navigating some lingering cultural expectations, such as social pressure around alcohol and family norms, which are gradually softening as the LDS share of the population diminishes.
How has the Mormon percentage changed over time?
Historically, the Salt Lake Valley was nearly 100% Mormon for much of the 19th and early 20th centuries, but the LDS share began to decline after World War II as Utah grew more connected to the rest of the United States. By the 2010s, Mormons had slipped below 50% in Salt Lake County for the first time in modern record-keeping, a turning point that demographers have labeled the "end of Mormon majoritarianism" in the region.
How does Salt Lake City compare to the rest of Utah?
Utah as a whole remains about 55% LDS, with some estimates approaching 60-68% based on church membership rolls, whereas Salt Lake City and its county sit substantially below that benchmark. Rural counties and smaller cities in central and southern Utah often remain strongly Mormon-majority, creating a striking contrast between the state's interior and its increasingly cosmopolitan capital region.
What are the main non-Mormon groups in Salt Lake City?
The largest non-Mormon groups in the Salt Lake City area include Catholic and evangelical Protestant communities, as well as growing populations of Muslims, Buddhists, Hindus, and the religiously unaffiliated. These groups are supported by a network of mosques, temples, synagogues, and secular community centers that have expanded in tandem with the diversification of the metro population.
How is the LDS Church responding to these demographic changes?
The LDS Church has responded to demographic shifts around Salt Lake City by increasing emphasis on local congregational outreach, welfare services, and interfaith dialogue, while also investing more heavily in missionary work outside Utah. At the same time, leadership has cautiously adjusted policies on issues such as LGBTQ+ inclusion and women's roles, in part to retain members in an increasingly pluralistic and secular environment.
