How Many Mormons Live In Utah? The Latest Figures
As of the most recent estimates (2024-2025), roughly 2.1 million people in Utah identify as members of The Church of Jesus Christ of Latter-day Saints (LDS Church), commonly referred to as Mormons. This represents about 60% of Utah's total population, making it the state with by far the highest concentration of Latter-day Saints in the United States.
Current population breakdown
The size of Utah's Mormon population is best understood through both official church membership records and independent demographic surveys. According to the LDS Church's April 2024 statistical report, Utah accounts for approximately one-third of global membership in the faith, reflecting its historical and cultural centrality.
- Total Utah population (2025 estimate): ~3.5 million residents.
- LDS Church members in Utah: ~2.1 million.
- Percentage of Utah residents identifying as Mormon: ~60%.
- Active participation rate (weekly attendance): estimated 35-45% of members.
- Number of congregations (wards and branches): over 5,300 statewide.
The distinction between formal membership and active participation is critical when interpreting the Utah religious landscape. While official records include baptized members, surveys from organizations like Pew Research Center suggest a smaller share regularly attends services or participates in church activities.
Historical growth of Mormon population
Utah's Mormon population has deep roots dating back to 1847, when Brigham Young led Mormon pioneers into the Salt Lake Valley. Since then, the state has remained the global hub of the faith, with steady population growth driven by both high birth rates and migration patterns.
- 1847-1900: Early settlement period; LDS members comprised over 90% of Utah Territory residents.
- 1900-1950: Gradual diversification; Mormon share dropped to about 70-75%.
- 1950-2000: Rapid population growth; increasing in-migration reduced percentage to ~65%.
- 2000-2025: Continued diversification; current share stabilizes around 60%.
Demographers note that Utah's shift from overwhelming religious homogeneity to a more mixed population reflects broader trends in American religious change, including secularization and migration from other states.
County-level distribution
The concentration of Mormon residents varies significantly by region. Rural counties tend to have much higher percentages of LDS members, while urban areas like Salt Lake County show greater diversity.
| County | Estimated LDS % | Population (2025 est.) | Notes |
|---|---|---|---|
| Utah County | 80-85% | 700,000 | Strongest LDS concentration; includes Provo |
| Davis County | 70-75% | 370,000 | High family-based membership |
| Salt Lake County | 45-50% | 1.2 million | Most religiously diverse county |
| Weber County | 55-60% | 280,000 | Moderate LDS majority |
| Rural counties (avg) | 75-90% | Varies | Very high LDS concentration |
This regional variation highlights how urbanization influences the religious demographic balance in Utah, with cities attracting more religiously diverse populations.
Why Utah has so many Mormons
The high concentration of Mormons in Utah is not coincidental; it is the result of historical migration, cultural continuity, and institutional presence. The LDS Church established Utah as its headquarters in the 19th century, shaping its development from the beginning.
- Historical settlement by Mormon pioneers in 1847.
- Headquarters of the LDS Church located in Salt Lake City.
- Strong cultural emphasis on family and community growth.
- Higher-than-average birth rates among LDS families.
- Migration patterns of members moving to Utah for education or employment.
These factors combine to reinforce Utah's identity as the global center of the Latter-day Saint community, even as its population becomes more diverse over time.
Membership vs. cultural identity
Not everyone counted as Mormon in Utah actively practices the faith. Researchers distinguish between official membership and self-identified religious affiliation, which can differ significantly.
A 2023 survey by the Public Religion Research Institute found that while about 60% of Utah residents are on LDS membership rolls, only about 52% self-identify as Mormon in daily life. This gap reflects shifts in belief, activity levels, and generational attitudes toward religion within the modern Utah population.
"Utah remains the heart of the LDS Church, but it is no longer monolithic," said sociologist Benjamin Knoll in a 2024 regional study. "Religious identity here is becoming more fluid, especially among younger residents."
Growth trends and future projections
Population projections suggest that while the absolute number of Mormons in Utah will continue to grow, their percentage share may gradually decline as the state attracts newcomers from across the U.S. and abroad.
- Projected Utah population by 2035: ~4.3 million.
- Projected LDS membership: ~2.4-2.6 million.
- Estimated percentage: 50-55%.
- Key driver: in-migration of non-LDS residents.
This trend reflects broader national patterns of religious diversification, placing Utah at a crossroads between tradition and change within the U.S. demographic evolution.
Global context
Although Utah has the highest concentration of Mormons, most LDS Church members now live outside the United States. As of 2024, global membership exceeds 17 million, with rapid growth in Latin America, Africa, and the Philippines.
Utah's 2.1 million members therefore represent a significant but shrinking share of the global church, underscoring the international expansion of the LDS global membership in recent decades.
