Arizona’s population has grown 6% since 2020 and is up 1.5% between 2023 and 2024, according to the latest estimates from the U.S. Census Bureau.
The state’s total population sits at almost 7.6 million people. Arizona is 10th for percent growth and eighth for numeric growth over the last year, which saw more than 109,000 new resident arrivals.
Nine states added more than 100,000 people each between July 2023 and July 2024. The national population rose 1%, with Texas leading growth and adding 563,000 people. California led additions in the western region with more than 232,500.
Despite California’s population gains, it is also one of the primary contributors of new residents to Arizona. In the past decade, 630,000 Californians – 173/day – have relocated to Arizona.
All the state’s new residents have made marked contributions to the Arizona economy. The median household income rose from $72.6K in 2023 to nearly $76.9K in 2024. Maricopa County, which is the primary home for new arrivals, saw its median household income rise from $80.7K to $85.8K.
New tax filers in 2021 and 2022 contributed $1.8B to Maricopa County, according to IRS and Census Bureau information. (Source)
