Utah County added the most people, with 21,853 new residents. That’s been the pattern for the past five years. The institute reported Utah County saw 43% of the state’s population growth in the 2024 estimates. Salt Lake County came in second with 12,113 new residents and 57% of its population growth was due to natural increase.

No longer the state with the highest birth rates in the U.S., Utah's population continues to grow — but slowly.

State growth slowed down some, but its population still surpassed 3.5 million in 2024, according to a new state population report.

Utah County has seen the biggest population increase in the state over one year, according to the Kem C Gardner Policy Institute.
