What Parts of Utah Are Growing the Fastest?

A current look at the Utah communities and counties seeing the strongest population growth, what is driving that growth, and what buyers should consider before choosing a fast-growing area.

Utah continues to add residents, but the growth is not spread evenly across the state. Some communities are expanding rapidly as new homes, infrastructure, jobs, and services follow population demand. For home buyers, understanding where growth is concentrated can help explain why certain areas are seeing new construction, changing neighborhoods, and increased demand.

The latest Utah Population Committee estimates show that Utah’s population increased by 44,351 people between 2024 and 2025, reaching an estimated 3,551,150 residents. The statewide growth rate moderated to 1.3%, but several counties and communities grew considerably faster than the state overall. Tooele and Iron counties were the fastest-growing counties by percentage at 3.0% each, while Utah County added the largest number of residents.

Utah County Is One of the State’s Biggest Growth Engines

Utah County stands out because of the sheer number of new residents it is adding. The Utah Population Committee estimated that the county added 15,914 residents between 2024 and 2025, accounting for roughly 36% of Utah’s total population growth during the year. That makes Utah County the largest contributor to statewide numeric growth.

The county also contains several communities that rank among Utah’s fastest-growing places. Saratoga Springs and Eagle Mountain led the state’s communities with populations of 20,000 or more in both absolute and percentage growth in the 2024–2025 estimates. Washington, Spanish Fork, and other Utah County communities also appear prominently among the state’s fastest-growing places.

For buyers, that growth can translate into a wider range of newer housing, new commercial development, expanding services, and changing commute patterns. But fast growth can also mean construction activity, traffic changes, evolving school and service needs, and neighborhoods that may look substantially different five or ten years from now.

New residential construction is one visible sign of population growth in expanding Utah communities.

Saratoga Springs Is Growing at a Remarkable Pace

Saratoga Springs is one of the clearest examples of rapid population expansion. The Utah Population Committee’s 2024–2025 estimates placed the city first among Utah communities with at least 20,000 residents for percentage growth, at about 8.4%, and it also led the state in the number of residents added.

The U.S. Census Bureau’s Vintage 2025 QuickFacts separately estimates that Saratoga Springs grew 62.8% from its 2020 population-estimate base to 61,397 residents in 2025. The two sources use different estimation approaches and comparison periods, but both point to substantial growth.

Its location along Utah Lake and within the broader Utah County growth corridor makes it a natural area for new residential development. For buyers, the attraction may include newer homes, planned communities, and access to outdoor recreation. At the same time, a rapidly developing market requires buyers to investigate commute times, future construction, local services, and neighborhood plans rather than judging a property only by how it looks today.

Eagle Mountain Remains One of Utah’s Fastest-Growing Cities

Eagle Mountain is another major growth center in Utah County. The U.S. Census Bureau ranked Eagle Mountain ninth nationally among cities and towns with 20,000 or more residents for percentage population growth from July 2024 to July 2025, with an 8.5% increase and a 2025 population estimate of 66,557. Utah’s population estimates also identified Eagle Mountain as one of the state’s top growth communities.

The growth story is closely connected to land availability, new housing, and the expansion of the broader Utah County region. For prospective buyers, Eagle Mountain can illustrate an important point: a fast-growing city may offer new housing opportunities, but the buyer should also think about distance to work, transportation, services, and how quickly surrounding infrastructure is developing.

Washington County Is a Major Southern Utah Growth Center

Growth is not limited to northern Utah. Washington County is one of the state’s strongest growth areas and has become a major population center in southern Utah. The Utah Population Committee estimated that Washington County grew 2.3% in 2025, while adding 4,751 residents. The county’s population reached an estimated 213,670 in the U.S. Census Bureau’s 2025 QuickFacts, representing an 18.5% increase from its 2020 estimate base.

St. George remains the county’s largest and best-known population center. The city reached an estimated 108,713 residents in 2025, according to Census QuickFacts, up 14.0% from its 2020 estimate base. Washington, another community in the county, was also among Utah’s fastest-growing cities in the 2024–2025 estimates.

Southern Utah offers a different lifestyle from the Wasatch Front, with warmer weather, red-rock scenery, outdoor recreation, and a growing service and residential economy. Buyers considering the area should evaluate water, heat, insurance, commute patterns, and the specific neighborhood’s future development plans along with the home itself.

Southern Utah’s expanding communities combine residential development with distinctive desert and mountain landscapes.

Tooele County Is Growing Quickly on the West Side of the Wasatch Front

Tooele County is another area worth watching. The Utah Population Committee estimated that Tooele County grew 3.0% in 2025, tying Iron County for the fastest percentage growth among Utah counties. The county also added about 2,466 residents, placing it among the state’s larger contributors to numeric growth.

The county’s position west of the Salt Lake Valley gives buyers a different combination of housing, land, commuting options, and community character. As more households move into the area, development can bring new homes and services while also increasing transportation demand.

A buyer considering Tooele should compare the purchase price with the total cost of ownership and the time required for daily commuting. A lower-priced home can become less attractive if a longer commute adds substantial time and transportation costs.

Iron County Is One of the Fastest-Growing Counties by Percentage

Iron County also recorded 3.0% population growth in 2025, matching Tooele County for the state’s fastest county-level growth rate. Cedar City, the county’s primary population center, ranked among Utah’s fastest-growing communities in the 2024–2025 estimates, with about 2.8% growth.

Cedar City can appeal to buyers who want a smaller community with access to outdoor recreation and a different pace from the Wasatch Front. As with any fast-growing area, buyers should look beyond population statistics and examine employment options, schools, services, housing inventory, and future development.

Other Communities Showing Strong Growth

The 2024–2025 Utah Population Committee estimates identified several other communities with notable growth. West Haven, Spanish Fork, Magna, Heber City, Tooele, Hurricane, and Cedar City were among the top ten communities by percentage growth for places with populations of at least 20,000. Utah County accounted for half of the top ten communities, reinforcing how important the county is to Utah’s current growth pattern.

The pattern is broader than just a handful of cities. The Gardner Policy Institute reported that 172 Utah communities grew between 2024 and 2025, with growth led by communities in Utah, Salt Lake, Washington, and Tooele counties. The same research found that smaller communities can also grow rapidly, with Salem, Mapleton, and Nibley leading the 5,000–19,999 population category.

New neighborhoods can expand quickly as population growth creates demand for additional housing.

Why Are These Areas Growing?

Population growth usually reflects several factors working together rather than one single cause. Utah’s Governor’s Office of Planning and Budget says the state’s growth has historically been associated with its economy and quality of life, while noting that growth has not been evenly distributed. It projects that urban areas, particularly the Wasatch Front and Washington County, will contain most of the state’s new residents over the coming decades.

Housing availability is another important factor. When land can be developed and new homes can be built, communities can absorb population increases more quickly. Transportation projects, employment centers, schools, retail, healthcare, and recreational amenities can then reinforce the appeal of an area.

For buyers, this means growth can create both opportunity and pressure. New construction may provide more housing choices, while population growth can also increase competition for desirable homes and put pressure on roads and public services.

What Fast Growth Means for Home Buyers

More new construction: Rapidly growing communities often have active residential development and a wider selection of newer homes.

Changing infrastructure: Roads, schools, utilities, retail, and public services may expand as the population increases.

Longer or changing commutes: A community can become more connected over time, but rapid population growth can also increase traffic.

Different investment dynamics: Growing neighborhoods can benefit from increased demand, but future appreciation is never guaranteed.

More choices, but more homework: Buyers should investigate planned developments, zoning, utilities, taxes, HOA costs, and neighborhood conditions.

A changing community character: The quiet edge of town today may become a much busier residential corridor in the future.

How Should Buyers Evaluate a Fast-Growing Area?

Population growth can be useful information, but it should not be the only reason to buy a home. A fast-growing city may be a great fit for one buyer and a poor fit for another. Start by comparing the things that affect your daily life: commute, housing budget, home style, lot size, schools, recreation, shopping, healthcare, and neighborhood feel.

Then look forward. Research planned roads, new subdivisions, commercial development, zoning changes, schools, utilities, and other projects that could affect the area. If you are considering a home on the edge of an existing community, ask what is planned around it. The surroundings can change considerably during a period of rapid growth.

Finally, compare the full cost of living in the area. A lower purchase price may be attractive, but taxes, insurance, HOA fees, utilities, maintenance, and commuting costs can change the financial picture.

Frequently Asked Questions

What part of Utah is growing the fastest?

Recent 2024–2025 Utah Population Committee estimates show Saratoga Springs and Eagle Mountain leading Utah’s larger communities in both absolute and percentage growth. At the county level, Tooele and Iron counties had the fastest percentage growth at 3.0% each in 2025.

Is Utah County still growing quickly?

Yes. Utah County added an estimated 15,914 residents in 2025, roughly 36% of Utah’s statewide population increase.

Is southern Utah growing too?

Yes. Washington County grew an estimated 2.3% in 2025, and St. George continued to add residents. Several southern Utah communities also appeared among the state’s fastest-growing places.

Does fast population growth mean home prices will rise?

Not necessarily. Growth can support housing demand, but home prices are influenced by interest rates, inventory, employment, affordability, construction, and broader market conditions. Buyers should not treat population growth alone as a guarantee of appreciation.

Should I buy in a fast-growing Utah city?

It can make sense if the community fits your budget, commute, lifestyle, and long-term plans. Research the current neighborhood and planned future development before making a decision.

The Bottom Line

Utah’s growth is concentrated, and the latest data show especially strong expansion in Utah County, Washington County, Tooele County, Iron County, and several fast-growing cities. Saratoga Springs and Eagle Mountain stand out among larger communities, while Spanish Fork, West Haven, Heber City, Tooele, Hurricane, and Cedar City also show meaningful growth.

For home buyers, the most useful question is not simply where the population is growing fastest. It is whether the growth pattern creates the right combination of housing, commute, services, lifestyle, and long-term fit for your household. Fast growth can bring opportunity, but it also requires more research.
