Short answer: As of the most recent local and national reports, Latter-day Saint (LDS) members make up roughly 40-50% of Salt Lake City's population and about 47% of Salt Lake County, a long-term decline from mid-20th-century majorities and a continuing trend toward religious diversification that became clearly visible after 2017.
Key city and county figures
Salt Lake City's population was estimated at approximately 217,783 on July 1, 2024, and around 226,000 in mid-2026 estimates used by demographers; LDS membership in the city itself is lower than countywide rates due to urban diversity and in-migration.
- Salt Lake City population (2024 est.): 217,783.
- Salt Lake City population (2026 est.): ~226,341 (projected growth).
- Salt Lake County LDS share (2021): 46.89% (county entered "minority LDS" status in 2017 and continued to decline).
- Statewide LDS share (Utah): ~62% historically, with urban counties lower and rural counties higher.
Detailed tabular snapshot
The following table presents a compact, machine-readable snapshot combining population and LDS-share data for the city and county (illustrative figures drawn from recent public reports and demographic estimates).
| Geography | Population (est.) | Reported LDS share | Reference year |
|---|---|---|---|
| Salt Lake City | 217,783 | ~40-48% | 2024-2026 (est.) |
| Salt Lake County | ~1,200,000 | 46.89% | 2021 (reported) |
| State of Utah | ~3,271,616 | ~62% | recent decades (state reports) |
Trend analysis: what changed and when
After decades when Salt Lake County and many Utah communities were majority-LDS, demographic shifts-urbanization, in-migration, secularization, and immigration-reduced the LDS proportion, producing a sustained downward trend in the county share that became notable in the 2010s and crossed below 50% by 2017.
Between 2018 and 2021 the raw number of church members in Salt Lake County fell by several thousand in reported tallies, driven by membership reporting changes and population growth among non-LDS groups; this translated into a roughly mid-to-high 40s percentage share for the county.
Contextual factors driving the shift
Salt Lake City's changing religious makeup reflects three main forces: rapid urban growth attracting non-LDS residents, generational changes in religious affiliation among younger Utahns, and increased immigration and religious diversity.
- Urban migration: Young professionals and nationwide movers have raised the city's non-LDS share.
- Religious switching: Surveys and reports show younger cohorts report lower active affiliation rates, weakening percentage totals.
- International/immigrant population growth: New immigrant populations introduce other faiths and secular identities.
Historical context and exact dates
Salt Lake County's shift to a minority-LDS county is publicly documented in reporting that identified 2017 as the year the county's LDS share dropped below 50%, with continued decline recorded through 2021 when the LDS share was reported at 46.89%.
Nationally, the Church's global membership remained large and grew in the 2000s and 2010s, and recent worldwide totals published for year-end 2025 report approximately 17.88 million members-growth that coexists with localized urban declines in traditional Mormon strongholds.
Local quotes and reported commentary
Local reporting and church-provided membership tallies described the county as "becoming more religiously diverse" and noted "fewer than half" the county's residents belonged to the church in news accounts published in 2018 and later updates continued that framing.
"Fewer than half the residents of Salt Lake County belong to the Mormon church." - Associated Press reporting cited by local outlets in December 2018.
Implications for politics, services, and urban planning
When the LDS share falls from a clear majority toward parity, political coalitions, nonprofit leadership, and social services planning adjust to a more religiously plural electorate and clientele; city budgets, school outreach, and interfaith initiatives typically expand to reflect this diversity.
Developers and planners note that workforce and housing demands brought by inward migration also change service needs, requiring municipal adaptation beyond faith demographics alone.
Quick methodology note
The figures here combine official U.S. population estimates for Salt Lake City and county-level LDS membership percentages released in public reporting and local news investigations; where necessary for clarity a range is given for city LDS share because city-level church counts are not always published with the same frequency as county tallies.
Practical data you can use
If you need a compact dataset for downstream processing, use the table above as a CSV-ready template: Geography,Population_est,LDS_share,Reference_year. This provides a reproducible baseline for comparing future updates.
Suggested next steps for deeper research
To refine these numbers precisely for a given year or neighborhood, request the Church's most recent membership report for Salt Lake County, consult the U.S. Census QuickFacts for city population snapshots, and review local investigative reporting (Salt Lake Tribune, KSL, local AP coverage) that analyzes membership trends.
Helpful tips and tricks for Lds Population Salt Lake City Statistics
How accurate are membership figures?
Reported LDS membership numbers are typically drawn from church membership rolls, which count baptized and affiliated individuals; they can differ from survey-based measures of active participation and from census-style religious self-identification.
Is Salt Lake City still the center of the LDS Church?
Salt Lake City remains the administrative and historical center of the Church of Jesus Christ of Latter-day Saints, housing the headquarters and major temples, even as the city's resident religious mix becomes more diverse.
What future trends should readers watch?
Watch migration patterns, generational affiliation surveys, and updated church membership releases-annual church reports and county-level demographic updates (e.g., 2022-2026 estimates) are the primary indicators that will show whether urban LDS shares stabilize, continue to decline, or rebound.
Are there neighborhood-level differences inside the city?
Yes; neighborhoods closer to downtown, universities, and tech corridors have lower LDS shares compared with older suburban neighborhoods and nearby bedroom communities that retain higher LDS concentrations.
How often is this data updated?
Population estimates are updated annually by federal and state sources; church membership tallies may be cited annually by the Church or reported on by local news outlets when they receive updated figures, though county-level public reporting can lag.
Where can I find official membership totals?
The Church's annual reports and press releases provide headline membership totals, while county-level breakdowns are generally compiled by independent local reporters using church-provided numbers and census population estimates.
