Provo is still Utah County's biggest city, at an estimated 114,527 people. The news in the Census Bureau's 2025 estimates is the next spot down: Lehi (95,313) has slipped past Orem (95,214), by 99 people, to become the county's second-largest city.
Every figure below is from the U.S. Census Bureau's Vintage 2025 city and town population estimates, released May 14, 2026, for July 1, 2025. Growth is measured from the Census Bureau's April 2020 estimates base. The Utah Population Committee publishes separate estimates that differ for some cities; see Utah County's fastest-growing cities in 2025 for both.

What stands out
Lehi's climb. In the 2020 estimates base, Orem had about 22,000 more people than Lehi. Five years later Lehi is ahead, having grown 25.6% while Orem shrank 2.9%. The margin is small enough that the next year's estimates could flip it back.
The west side carried the growth. Eagle Mountain and Saratoga Springs together added about 46,600 people since 2020, nearly half of the county's growth. The Census Bureau's release ranked Eagle Mountain ninth among the fastest-growing U.S. cities of 20,000 or more between 2024 and 2025, at 8.5%.
The south county is catching up. Mapleton (+43.3%), Santaquin (+38.4%) and Salem (+31.6%) grew faster than Lehi in percentage terms since 2020.
The core is flat. Provo, Orem, Pleasant Grove, Springville and Cedar Hills all lost people between 2024 and 2025 in the Census Bureau's estimates.

A note on the numbers
These are estimates, built from births, deaths, migration and housing data, not a count. The Utah Population Committee's own 2025 estimates differ for several cities; it put Eagle Mountain at 65,409 and Saratoga Springs at 60,351, for example.
