Utah’s Population Surges Past 3.55 Million Despite Slower Growth

Utah’s population has reached a milestone, surpassing 3.55 million residents as of July 2025. This figure represents an increase of 44,351 individuals from the previous year, according to estimates released by the Kem C. Gardner Policy Institute at the University of Utah. Despite this growth, experts indicate a noticeable slowdown in the overall rate of population increase.

The latest estimate reflects a decline in the growth rate from 1.5% in 2024 to 1.3% in 2025. The data reveals that the majority of this growth stemmed from natural factors, predominantly births exceeding deaths, rather than migration, marking a significant shift in demographic trends.

Changing Dynamics in Population Growth

“Our 2025 estimates reveal a moderation in Utah’s population growth,” stated Emily Harris, senior demographer at the Gardner Institute and lead author of the report. “A significant shift occurred this year, with natural change contributing the majority of new Utahns, making it the primary driver of growth for the first time this decade.” This trend signifies a return to historical growth patterns seen prior to the recent surge in net migration.

The Wasatch Front remains the focal point of Utah’s population expansion. Within this region, both Salt Lake and Utah County experienced the highest increases in numbers, with 8,281 and 15,914 new residents, respectively. Despite these figures, both counties reported “substantial decreases” in growth due to reduced net migration. Together, they account for approximately 56% of the state’s total population.

Utah County has consistently been the largest contributor to statewide growth, a title it has maintained for the last six years. The county’s population increased by 2.1%, adding nearly 16,000 new residents. In contrast, Tooele and Iron County reported higher percentage increases of 3%. Tooele County welcomed 2,466 new residents, while Iron County added 2,042.

Population Declines in Certain Areas

Despite overall growth, the report highlighted that only five counties in Utah experienced a decline in population: Daggett, Piute, Garfield, Wayne, and San Juan. Among these, Garfield County faced the most significant setback, losing 41 residents, which constitutes a 0.8% decrease in its population.

As Utah navigates these demographic changes, the implications for infrastructure, housing, and community services will likely become a focal point for policymakers. The data underscores the importance of understanding local population dynamics as the state adapts to both natural growth and migration trends.

In summary, while Utah’s population has reached a new high, the slowing growth rate indicates a crucial shift that will require careful consideration in planning for the future. The state’s ability to accommodate its residents will depend on how effectively it responds to these emerging trends.
