SmartAsset’s latest study looks at which cities and states in the U.S. are seeing the biggest influx of Millennials moving to them. And can you guess the most popular destination for Millennials in Arizona?

Key Findings

• Tempe is the top city to which Millennials in Arizona are moving. Relative to the local population, the one-year influx of Millennials to Tempe is 9%  — a total of 17,134 people.
• After Tempe, the second biggest destination for Millennials in Arizona is Scottsdale, while the least popular is Goodyear.
• Nationwide, Oxnard, California was the least popular destination city for Millennial migration in the last year measured, white Cambridge, Massachusetts was the most popular.

Millennials now make up an estimated 36% of the workforce, making this cohort highly valuable to any local economy. With more flexibility than ever due to remote work and rapidly developing technologies, many Millennial households opt to move locations in pursuit of job opportunities, higher pay, preferable lifestyles, and family considerations, among other reasons. Locations that can attract Millennials may benefit from stronger and more diverse workforces, disposable income flowing to local businesses, and additional tax revenue. On the other hand, it can also lead to more competitive housing markets and a change in the business mix for preexisting locals.

With this in mind, SmartAsset ranked 254 of the largest U.S. cities based on the relative popularity among Millennials (those aged 25 to 44) who moved to that city in 2024.
