These areas of the country are attracting the most new residents and seeing the fastest economic expansion in the U.S., according to a new analysis.

The city of Provo, Utah, is the biggest boomtown in America, gaining the most new residents and experiencing the sharpest economic expansion in the nation, according to a new analysis by background check company Checkr. In fact, Utah claims four of the biggest boomtowns in the U.S.

Checkr’s analysis defines a “boomtown” as a city that has experienced rapid economic growth and development in a short period of time. Using data from the Census Bureau and the Bureau of Economic Analysis, Checkr factored in metrics like growth in population, workforce, housing units, personal income and businesses to compile its list of America’s biggest boomtowns in 2023.

Besides Provo, cities in Utah that made the list include St. George (number five), Logan (number eight) and Ogden (number nine). “Utah has fostered a business-friendly environment that has attracted companies from various industries, including technology, finance, health care and outdoor recreation,” researchers note. “This has led to job opportunities and a steady influx of professionals and skilled workers seeking employment in these thriving sectors.”
