More than half of Utahns live in a city with a population of 50,000 or more for the first time in state history, according to a population report. It comes as 172 communities across Utah gained population between mid-2024 and mid-2025, while the rest either didn’t experience any changes or lost population, the Utah Population Committee, which is overseen by the University of Utah Kem C. Gardner Policy Institute, noted in a subcounty population estimate report on Tuesday.
